Problem with entityManagerFactoryBean.setPersistenceProviderClass

[Alejandro Barrero]

In a previous project I have in a class

	@Bean
	public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
		LocalContainerEntityManagerFactoryBean entityManagerFactoryBean = new LocalContainerEntityManagerFactoryBean();
		entityManagerFactoryBean.setDataSource(dataSource());
		entityManagerFactoryBean.setPersistenceProviderClass(HibernatePersistence.class);
		entityManagerFactoryBean
				.setPackagesToScan(env.getRequiredProperty(PROPERTY_NAME_ENTITYMANAGER_PACKAGES_TO_SCAN));
		entityManagerFactoryBean.setJpaProperties(hibProperties());
		return entityManagerFactoryBean;
	}

HibernatePersistence is flagged as deprecated but it worked.  In a new project i could not import org.hibernate.ejb.HibernatePersistence. I read that it is better to use HibernatePersistenceProvider but now I cannot import org.hibernate.jpa.HibernatePersistenceProvider. I have spend hours to find what dependency I should use in Mave without any results.

Well, if you're willing to define one externally, here's something that I use. Note that this is Hibernate JPA, not legacy Hibernate, and that the connection pool information is supplied external to the webapp via JNDI:
   <!-- Persistence Definitions -->    <bean id="entityManagerFactory"            class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">       <property name="dataSource" ref="myDataSource" />       <property name="loadTimeWeaver">             <bean                      class="org.springframework.instrument.classloading.InstrumentationLoadTimeWeaver" />       </property>       <property name="packagesToScan" value="com.mousetech.myapplication.persistence.model"/>       <property name="jpaPropertyMap" ref="jpaPropertyMap"/>       <property name="jpaVendorAdapter">          <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">              <property name="showSql" value="false" />              <property name="generateDdl" value="true" />              <property name="databasePlatform" value="org.hibernate.dialect.DB2Dialect" />          </bean>       </property>            </bean>    <util:map id="jpaPropertyMap">        <entry key="hibernate.hbm2ddl.auto" value="update"/>        <entry key="hibernate.dialect" value="org.hibernate.dialect.DB2Dialect"/>    </util:map>            <bean                class="org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor" />    <bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">                <property name="entityManagerFactory" ref="entityManagerFactory" />    </bean>    <tx:annotation-driven />    <!--  I think AOP obsoletes this: -->    <bean id="transactionInterceptor"              class="org.springframework.transaction.interceptor.TransactionInterceptor">               <property name="transactionManager" ref="transactionManager" />                <property name="transactionAttributeSource">                        <bean                                class="org.springframework.transaction.annotation.AnnotationTransactionAttributeSource" />                </property>     </bean>

This setup is designed to inject EntityManagers directly into the DAOs used by the webapp via their @PersistenceContext annotations. It's a little old, so there may be some cruft and/or anachronisms in it, but it worked last time I deployed with it.
