Hibernate.dialect = net.sf.hibernate.dialect.SybaseDialect hibernate.showsql = true We will get back to executing this example shortly. What does Hibernate offer? Hibernate is an open source (released under LPGL) product for providing seamless persistence for Java objects. It uses reflections and yet provides excellent performance.
This class is designed for Java programmers with a need to understand the Java persistence provided by Hibernate or JPA framework and API. Students should have a good understanding of the Java programming language. A basic understanding of relational databases and SQL is very helpful. Object Persistence Persistence.
- Java Development Kit (JDK 1.8 or above)
- MySQL, includes MySQL database server, MySQL Command Line Client, and MySQL Workbench tool (MySQL 5.5 or above)
- Eclipse IDE (Neon or later) Here are the steps you will follow in this tutorial: 1. Overview of JPA and Hibernate Lets understand some fundamentals about JPA and Hibernate before writing code. Java Persistence API (JPA): JPA is a Java API specification for relational data management in applications using Java SE and Java EE. JPA defines a standard way for simplifying database programming for developers, reduce development time and increase productivity.When using JPA, you have to import interfaces and classes from the package javax.persistence.
JPA defines Java Persistence Query Language (JPQL) which is an object-oriented query language. The syntax of JPQL is similar to SQL but it operates against Java objects rather than directly with database tables.Remember JPA is a specification, and Hibernate is one of its implementations, among others such as EclipseLink and OpenJPA. Hibernate Framework: Hibernate is a popular Object Relational Mapping (ORM) framework that aims at simplifying database programming for developers.Hibernate was developed before JPA. And after JPA becomes a standard, Hibernate restructures itself to become an implementation of JPA.The Hibernate framework consists of several components: Hibernate ORM, Hibernate Search, Hibernate Validator, Hibernate CGM and Hibernate Tools. In this tutorial, we use Hibernate ORM which is the core component of the Hibernate framework, for mapping Java model classes to tables in a relational database. 2. Create MySQL Database Use the following statement to create a database named usersdb using MySQL Workbench or MySQL Command Line Client:Then create a table name users with 4 columns: user_id , fullname , email and password , using the following script:Using desc users command in MySQL Command Line Client, the structure of the table looks like this:Note that the column user_id is the tables primary key and it is auto-increment. 3. Setup Java Maven Project in Eclipse In Eclipse IDE, click File New Project and select Maven Maven Project in the New Project dialog. Then click Next .In the next screen, check the option Create a simple project (skip archetype selection) , and then click Next .In the New Maven Project screen, enter the projects information as follows:
- Group Id: net.codejava.hibernate
- Artifact Id: HibernateJPABeginner Leave other things as they are and click Finish . In the Project Explorer view, you see the project gets created with the following structure: Configure Maven Dependencies: Next, we need to add dependencies in Mavens Project Object Model ( pom.xml ) for Hibernate, JPA and MySQL Connector Java. Open the pom.xml file in XML mode and insert the following XML just before the /project tag:You see, here we add two dependencies for the project: hibernate-core and mysql-connector-java . Maven automatically downloads the required JAR files which are shown under the Maven Dependencies node in the project:You see, we just specify the dependency hibernate-core , but Maven can analyze and download all the dependencies of hibernate-core as well. Thats really helpful, right?Create a new Java package name net.codejava.hibernate under the src/main/java folder. Well put our Java classes in this package. 4. Code Model Class Next, lets create a domain model class named User . Then we will use JPA annotations to map this table to the corresponding table in the database.Heres the initial code of the User class:You see, this is just a POJO (Plain Old Java Object) class with some instance fields and its getter and setter methods. Now, lets use some annotations provided by JPA to map this model class to the users table in the database. @Entity This annotation indicates that the class is mapped to a database table. By default, the ORM framework understands that the class name is as same as the table name. The @Entity annotation must be placed before the class definition: @Table This annotation is used if the class name is different than the database table name, and it is must placed before the class definition. Since the class name is User and the table name is Users , we have to use this annotation: @Column This annotation is used to map an instance field of the class to a column in the database table, and it is must placed before the getter method of the field. By default, Hibernate can implicitly infer the mapping based on field name and field type of the class. But if the field name and the corresponding column name are different, we have to use this annotation explicitly. ThisIn our model class, the field name id is different than the column user_id , so we have to use the @Column annotation as follows:The other fields (fullname, email and password) have identical names as the corresponding columns in the table so we dont have to annotate those fields. @Id This annotation specifies that a field is mapped to a primary key column in the table. Since the column user_id is a primary key, we have to use this annotation as follows: @GeneratedValue If the values of the primary column are auto-increment, we need to use this annotation to tell Hibernate knows, along with one of the following strategy types: AUTO , IDENTITY , SEQUENCE , and TABLE . In our case, we use the strategy IDENTITY which specifies that the generated values are unique at table level, whereas the strategy AUTO implies that the generated values are unique at database level.Therefore, the getter method of the field id is annotated as follows:Finally, we have the model class User is annotated as follows: 5. Create JPA Configuration File (persistence.xml) Next, we need to create an XML configuration file for JPA called persistence.xml , in order to tell Hibernate how to connect to the database. This file must be present in the classpath, under the META-INF folder.Under the src/main/resources folder, create a new folder named META-INF (Right-click, select New Other Folder ).Right click on the newly created folder META-INF , select New Other XML XML File . Enter the file name as persistence.xml . And paste the following XML code:The root element persistence specifies the version of JPA to be used, and as you can see, we use JPA version 2.1.The element persistence-unit specifies a unit of persistence with a name. The name ( UsersDB ) will be looked up by Java code.Then we specify several properties for database connection information:
- javax.persistence.jdbc.url : specifies the JDBC URL points to the database.
- javax.persistence.jdbc.user : specifies the username of the account having privilege to access to the database. Flexi pro software .
- javax.persistence.jdbc.password : specifies the password of the user.
- javax.persistence.jdbc.driver : specifies the class name of the JDBC driver to be used. Here we use MySQL Connector Java so the name is com.mysql.jdbc.Driver .
- hibernate.show_sql : tells Hibernate to show SQL statements in standard output.
- hibernate.format_sql : tells Hibernate to format the SQL statements. So you may need to change the values for url , user , and password accordingly. 6. Understand EntityManager and EntityManagerFactory Finally, we need to code a test program to check if everything weve done so far is correct or not. But lets understand a couple of key interfaces in JPA first. EntityManager: An EntityManager instance is associated with a persistence context, and it is used to interact with the database.A persistence context is a set of entity instances, which are actually the objects or instances of the model classes.So we use the EntityManager to manage entity instances and their life cycle, such as create entities, update entities, remove entities, find and query entities. EntityManagerFactory : An EntityManagerFactory is used to create an EntityManager . And EntityManagerFactory is associated with a persistence unit. In Java SE environments, an EntityManagerFactory can be obtained from the Persistence class.And here are the typical steps to manage entity instances via JPA:
- Create an EntityManagerFactory from a persistence unit
- Create an EntityManager from the EntityManagerFactory
- Begin a transaction
- Manage entity instances (create, update, remove, find, query, etc)
Marks head bobbers and hand jobbers jada and will smith open marriage . - Commit the transaction
- Close the EntityManager and EntityManagerFactory Lets see the code details below. 7. Code a Test Program Now, lets write some code to create, update, find, query and remove User entity instances using JPA. Create a new Java class under src/main/java folder called UserDAOTest.java , with the main() method. Persist an entity instance: In the main() method, add the following code to create an EntityManager and begin the transaction:And write the following code to saves a new User object to the database:As you can see, we call the persist(Object) method of the EntityManager class to save the User object to the underlying database.And finally commit the transaction and close the EntityManager and EntityManagerFactory :So the complete program should look like this:Run this program, and you should see the following output in the Console view:You see, Hibernate prints the SQL statement which is nicely formatted. That means the program has been executed successfully. You can check the result by typing the command select * from users in MySQL Command Line Client tool:You see, a new row created and you dont have to write any SQL statement, right? Thats the power of using Hibernate/JPA for database programming.Lets see how to perform other operations. Update an entity instance: The following code snippet updates an entity instance which is already persisted in the database:As you can see, we need to specify the ID of the object and use the merge(Object) method of the EntityManager class. Find an entity instance: To find an entity from the database, we use the method find(ClassT entityClass, Object primaryKey) of the EntityManager class. For example:This code finds the user with ID = 1 in the database. Execute a query: The following code snippet shows you how to execute a query (JPQL):Note that the query looks similar to traditional SQL syntax but it is not. The difference is JPQL operates against entity instances (Java objects) rather than tables in database. Remove an entity instance: And the following code demonstrates how to delete an entity instance:As you can see, this code removes the User object with ID = 1 from the database, first by looking up a reference based on the class type ( User.class ) and primary key value (1), then remove the reference.Thats how to get started with Hibernate/JPA with Eclipse and MySQL. We hope this tutorial is helpful for you. Happy coding! References: You can watch the video version of this tutorial here: Other Hibernate Tutorials:

A high-performance data access layer must resonate with the underlying database system. Knowing the inner workings of a relational database and the data access frameworks in use can make the difference between a high-performance enterprise application and one that barely crawls. This book is a journey into Java data access performance tuning. From connection management, to batch updates, fetch sizes and concurrency control mechanisms, it unravels the inner workings of the most common Java data access frameworks. The first part aims to reduce the gap between application developers and database administrators. For this reason, it covers both JDBC and the database fundamentals that are of paramount importance when reducing transaction response times. In this first part, you'll learn about connection management, batch updates, statement caching, result set fetching and database transactions. The second part demonstrates how you can take advantage of JPA and Hibernate without compromising application performance. In this second part, you'll learn about the most efficient Hibernate mappings (basic types, associations, inheritance), fetching best practices, caching and concurrency control mechanisms. The third part is dedicated to jOOQ and its powerful type-safe querying capabilities, like window functions, common table expressions, upsert, stored procedures and database functions.

This book is a collection of developer code recipes and best practices for persisting data using Spring, particularly Spring Boot. The book is structured around practical recipes, where each recipe discusses a performance case or performance-related case, and almost every recipe has one or more applications. Mainly, when we try to accomplish something (e.g., read some data from the database), there are several approaches to do it, and, in order to choose the best way, you have to know the implied trades-off from a performance perspective. Youll see that in the end, all these penalties slow down the application. Besides presenting the arguments that favor a certain choice, the application is written in Spring Boot style which is quite different than plain Hibernate. Persistence is an important set of techniques and technologies for accessing and using data, and this book demonstrates that data is mobile regardless of specific applications and contexts. In Java development, persistence is a key factor in enterprise, ecommerce, cloud and other transaction-oriented applications. After reading and using this book, you'll have the fundamentals to apply these persistence solutions into your own mission-critical enterprise Java applications that you build using Spring. What You Will Learn Shape *-to-many associations for best performances Effectively exploit Spring Projections (DTO) Learn best practices for batching inserts, updates and deletes Effectively fetch parent and association in a single SELECT Learn how to inspect Persistent Context content Dissect pagination techniques (offset and keyset) Handle queries, locking, schemas, Hibernate types, and more Who This Book Is For Any Spring and Spring Boot developer that wants to squeeze the persistence layer performances.

Hibernate.dialect = net.sf.hibernate.dialect.SybaseDialect hibernate.showsql = true We will get back to executing this example shortly. What does Hibernate offer? Hibernate is an open source (released under LPGL) product for providing seamless persistence for Java objects. It uses reflections and yet provides excellent performance.
This class is designed for Java programmers with a need to understand the Java persistence provided by Hibernate or JPA framework and API. Students should have a good understanding of the Java programming language. A basic understanding of relational databases and SQL is very helpful. Object Persistence Persistence.
- Java Development Kit (JDK 1.8 or above)
- MySQL, includes MySQL database server, MySQL Command Line Client, and MySQL Workbench tool (MySQL 5.5 or above)
- Eclipse IDE (Neon or later) Here are the steps you will follow in this tutorial: 1. Overview of JPA and Hibernate Lets understand some fundamentals about JPA and Hibernate before writing code. Java Persistence API (JPA): JPA is a Java API specification for relational data management in applications using Java SE and Java EE. JPA defines a standard way for simplifying database programming for developers, reduce development time and increase productivity.When using JPA, you have to import interfaces and classes from the package javax.persistence.
JPA defines Java Persistence Query Language (JPQL) which is an object-oriented query language. The syntax of JPQL is similar to SQL but it operates against Java objects rather than directly with database tables.Remember JPA is a specification, and Hibernate is one of its implementations, among others such as EclipseLink and OpenJPA. Hibernate Framework: Hibernate is a popular Object Relational Mapping (ORM) framework that aims at simplifying database programming for developers.Hibernate was developed before JPA. And after JPA becomes a standard, Hibernate restructures itself to become an implementation of JPA.The Hibernate framework consists of several components: Hibernate ORM, Hibernate Search, Hibernate Validator, Hibernate CGM and Hibernate Tools. In this tutorial, we use Hibernate ORM which is the core component of the Hibernate framework, for mapping Java model classes to tables in a relational database. 2. Create MySQL Database Use the following statement to create a database named usersdb using MySQL Workbench or MySQL Command Line Client:Then create a table name users with 4 columns: user_id , fullname , email and password , using the following script:Using desc users command in MySQL Command Line Client, the structure of the table looks like this:Note that the column user_id is the tables primary key and it is auto-increment. 3. Setup Java Maven Project in Eclipse In Eclipse IDE, click File New Project and select Maven Maven Project in the New Project dialog. Then click Next .In the next screen, check the option Create a simple project (skip archetype selection) , and then click Next .In the New Maven Project screen, enter the projects information as follows:
- Group Id: net.codejava.hibernate
- Artifact Id: HibernateJPABeginner Leave other things as they are and click Finish . In the Project Explorer view, you see the project gets created with the following structure: Configure Maven Dependencies: Next, we need to add dependencies in Mavens Project Object Model ( pom.xml ) for Hibernate, JPA and MySQL Connector Java. Open the pom.xml file in XML mode and insert the following XML just before the /project tag:You see, here we add two dependencies for the project: hibernate-core and mysql-connector-java . Maven automatically downloads the required JAR files which are shown under the Maven Dependencies node in the project:You see, we just specify the dependency hibernate-core , but Maven can analyze and download all the dependencies of hibernate-core as well. Thats really helpful, right?Create a new Java package name net.codejava.hibernate under the src/main/java folder. Well put our Java classes in this package. 4. Code Model Class Next, lets create a domain model class named User . Then we will use JPA annotations to map this table to the corresponding table in the database.Heres the initial code of the User class:You see, this is just a POJO (Plain Old Java Object) class with some instance fields and its getter and setter methods. Now, lets use some annotations provided by JPA to map this model class to the users table in the database. @Entity This annotation indicates that the class is mapped to a database table. By default, the ORM framework understands that the class name is as same as the table name. The @Entity annotation must be placed before the class definition: @Table This annotation is used if the class name is different than the database table name, and it is must placed before the class definition. Since the class name is User and the table name is Users , we have to use this annotation: @Column This annotation is used to map an instance field of the class to a column in the database table, and it is must placed before the getter method of the field. By default, Hibernate can implicitly infer the mapping based on field name and field type of the class. But if the field name and the corresponding column name are different, we have to use this annotation explicitly. ThisIn our model class, the field name id is different than the column user_id , so we have to use the @Column annotation as follows:The other fields (fullname, email and password) have identical names as the corresponding columns in the table so we dont have to annotate those fields. @Id This annotation specifies that a field is mapped to a primary key column in the table. Since the column user_id is a primary key, we have to use this annotation as follows: @GeneratedValue If the values of the primary column are auto-increment, we need to use this annotation to tell Hibernate knows, along with one of the following strategy types: AUTO , IDENTITY , SEQUENCE , and TABLE . In our case, we use the strategy IDENTITY which specifies that the generated values are unique at table level, whereas the strategy AUTO implies that the generated values are unique at database level.Therefore, the getter method of the field id is annotated as follows:Finally, we have the model class User is annotated as follows: 5. Create JPA Configuration File (persistence.xml) Next, we need to create an XML configuration file for JPA called persistence.xml , in order to tell Hibernate how to connect to the database. This file must be present in the classpath, under the META-INF folder.Under the src/main/resources folder, create a new folder named META-INF (Right-click, select New Other Folder ).Right click on the newly created folder META-INF , select New Other XML XML File . Enter the file name as persistence.xml . And paste the following XML code:The root element persistence specifies the version of JPA to be used, and as you can see, we use JPA version 2.1.The element persistence-unit specifies a unit of persistence with a name. The name ( UsersDB ) will be looked up by Java code.Then we specify several properties for database connection information:
- javax.persistence.jdbc.url : specifies the JDBC URL points to the database.
- javax.persistence.jdbc.user : specifies the username of the account having privilege to access to the database. Flexi pro software .
- javax.persistence.jdbc.password : specifies the password of the user.
- javax.persistence.jdbc.driver : specifies the class name of the JDBC driver to be used. Here we use MySQL Connector Java so the name is com.mysql.jdbc.Driver .
- hibernate.show_sql : tells Hibernate to show SQL statements in standard output.
- hibernate.format_sql : tells Hibernate to format the SQL statements. So you may need to change the values for url , user , and password accordingly. 6. Understand EntityManager and EntityManagerFactory Finally, we need to code a test program to check if everything weve done so far is correct or not. But lets understand a couple of key interfaces in JPA first. EntityManager: An EntityManager instance is associated with a persistence context, and it is used to interact with the database.A persistence context is a set of entity instances, which are actually the objects or instances of the model classes.So we use the EntityManager to manage entity instances and their life cycle, such as create entities, update entities, remove entities, find and query entities. EntityManagerFactory : An EntityManagerFactory is used to create an EntityManager . And EntityManagerFactory is associated with a persistence unit. In Java SE environments, an EntityManagerFactory can be obtained from the Persistence class.And here are the typical steps to manage entity instances via JPA:
- Create an EntityManagerFactory from a persistence unit
- Create an EntityManager from the EntityManagerFactory
- Begin a transaction
- Manage entity instances (create, update, remove, find, query, etc)
Marks head bobbers and hand jobbers jada and will smith open marriage . - Commit the transaction
- Close the EntityManager and EntityManagerFactory Lets see the code details below. 7. Code a Test Program Now, lets write some code to create, update, find, query and remove User entity instances using JPA. Create a new Java class under src/main/java folder called UserDAOTest.java , with the main() method. Persist an entity instance: In the main() method, add the following code to create an EntityManager and begin the transaction:And write the following code to saves a new User object to the database:As you can see, we call the persist(Object) method of the EntityManager class to save the User object to the underlying database.And finally commit the transaction and close the EntityManager and EntityManagerFactory :So the complete program should look like this:Run this program, and you should see the following output in the Console view:You see, Hibernate prints the SQL statement which is nicely formatted. That means the program has been executed successfully. You can check the result by typing the command select * from users in MySQL Command Line Client tool:You see, a new row created and you dont have to write any SQL statement, right? Thats the power of using Hibernate/JPA for database programming.Lets see how to perform other operations. Update an entity instance: The following code snippet updates an entity instance which is already persisted in the database:As you can see, we need to specify the ID of the object and use the merge(Object) method of the EntityManager class. Find an entity instance: To find an entity from the database, we use the method find(ClassT entityClass, Object primaryKey) of the EntityManager class. For example:This code finds the user with ID = 1 in the database. Execute a query: The following code snippet shows you how to execute a query (JPQL):Note that the query looks similar to traditional SQL syntax but it is not. The difference is JPQL operates against entity instances (Java objects) rather than tables in database. Remove an entity instance: And the following code demonstrates how to delete an entity instance:As you can see, this code removes the User object with ID = 1 from the database, first by looking up a reference based on the class type ( User.class ) and primary key value (1), then remove the reference.Thats how to get started with Hibernate/JPA with Eclipse and MySQL. We hope this tutorial is helpful for you. Happy coding! References: You can watch the video version of this tutorial here: Other Hibernate Tutorials:

A high-performance data access layer must resonate with the underlying database system. Knowing the inner workings of a relational database and the data access frameworks in use can make the difference between a high-performance enterprise application and one that barely crawls. This book is a journey into Java data access performance tuning. From connection management, to batch updates, fetch sizes and concurrency control mechanisms, it unravels the inner workings of the most common Java data access frameworks. The first part aims to reduce the gap between application developers and database administrators. For this reason, it covers both JDBC and the database fundamentals that are of paramount importance when reducing transaction response times. In this first part, you'll learn about connection management, batch updates, statement caching, result set fetching and database transactions. The second part demonstrates how you can take advantage of JPA and Hibernate without compromising application performance. In this second part, you'll learn about the most efficient Hibernate mappings (basic types, associations, inheritance), fetching best practices, caching and concurrency control mechanisms. The third part is dedicated to jOOQ and its powerful type-safe querying capabilities, like window functions, common table expressions, upsert, stored procedures and database functions.

This book is a collection of developer code recipes and best practices for persisting data using Spring, particularly Spring Boot. The book is structured around practical recipes, where each recipe discusses a performance case or performance-related case, and almost every recipe has one or more applications. Mainly, when we try to accomplish something (e.g., read some data from the database), there are several approaches to do it, and, in order to choose the best way, you have to know the implied trades-off from a performance perspective. Youll see that in the end, all these penalties slow down the application. Besides presenting the arguments that favor a certain choice, the application is written in Spring Boot style which is quite different than plain Hibernate. Persistence is an important set of techniques and technologies for accessing and using data, and this book demonstrates that data is mobile regardless of specific applications and contexts. In Java development, persistence is a key factor in enterprise, ecommerce, cloud and other transaction-oriented applications. After reading and using this book, you'll have the fundamentals to apply these persistence solutions into your own mission-critical enterprise Java applications that you build using Spring. What You Will Learn Shape *-to-many associations for best performances Effectively exploit Spring Projections (DTO) Learn best practices for batching inserts, updates and deletes Effectively fetch parent and association in a single SELECT Learn how to inspect Persistent Context content Dissect pagination techniques (offset and keyset) Handle queries, locking, schemas, Hibernate types, and more Who This Book Is For Any Spring and Spring Boot developer that wants to squeeze the persistence layer performances.

Pro JPA 2 introduces, explains, and demonstrates how to use the Java Persistence API (JPA). JPA provides Java developers with both the knowledge and insight needed to write Java applications that access relational databases through JPA. Authors Mike Keith and Merrick Schincariol take a handson approach to teaching by giving examples to illustrate each concept of the API and showing how it is used in practice. All of the examples use a common model from an overriding sample application, giving readers a context from which to start and helping them to understand the examples within an already familiar domain. After completing the book, you will have a full understanding and be able to successfully code applications using JPA. The book also serves as a reference guide during initial and later JPA application experiences.
