Hibernate JPA With H2 Database

Hibernate JPA With H2 Database explains step by step details of setting / configuring Java Persistence JPA With Hibernate And H2

How To Configure Hibernate JPA With H2?

Java Persistence API, is a standard interface which wraps different ORM tools such as  Hibernate, EclipseLink, OpenJPA etc.

ie; you can able to change Hibernate implementation to EclipseLink implementation without changing the code base.

On this standalone JPA Example, we are using Java Persistence With H2 Database

Hibernate is popular open source ORM (Object Relation Mapping) tool for Java platform, for mapping an entity to a traditional relational like Oracle, MySQL, SQL Server, PostgreSQL, DB2, Derby, Sybase, H2 etc

I am going to reuse JPA Tutorial With Hibernate


You need to remove classes12.jar (Oracle driver) and add h2.jar (H2 driver) into classpath

You can check below different database with Hibernate and EclipseLink examples

MySQL com.mysql.jdbc.Driver mysql-connector-java-5.1.25-bin.jar (exact name depends on version)

Modify persistence.xml

persistence.xml file must be under src/META-INF (Please check below screenshot(project structure)

Here we are using hibernate.dialect as "org.hibernate.dialect.H2Dialect". Below persistence.xml, we are using in-memory database, you can change this to file database by changing the URL to jdbc:h2:~/test

<persistence xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"
  version="2.0" xmlns="http://java.sun.com/xml/ns/persistence">
  <persistence-unit name="test" transaction-type="RESOURCE_LOCAL">
      <property name="javax.persistence.jdbc.driver" value="org.h2.Driver" />
      <property name="javax.persistence.jdbc.url"    value="jdbc:h2:mem:test" />
      <property name="javax.persistence.jdbc.user" value="sa" />
      <property name="javax.persistence.jdbc.password" value="" />
      <property name="hibernate.dialect" value="org.hibernate.dialect.H2Dialect"/>
      <property name="hibernate.hbm2ddl.auto" value="create-drop" />
      <property name="show_sql" value="true"/>
      <property name="hibernate.temp.use_jdbc_metadata_defaults" value="false"/>
