Hibernate + JPA Configuration Troubles

[harryoh]

Hi,

I'm fairly comfortable using Hibernate outside of Spring with Annotations. I personally prefer using annotations to map my POJOs (@Entity, @Id, etc.), but I just can't seem to figure out how to configure Hibernate/JPA.

How do I have the Spring container recognize that I'm using JPA annotations to map my POJOs? The following is my data source and session factory bean in application.xml:

        <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
		<property name="driverClassName" value="com.mysql.jdbc.Driver" />
		<property name="url" value="jdbc:mysql://localhost/_reviews" />
		<property name="username" value="xxxx" />
		<property name="password" value="xxxx" />
	</bean>
	
	<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
		<property name="dataSource" ref="dataSource" />
		<property name="mappingResources">
			<!-- No hbm.xml files. Just annotations. How do I configure it here? -->
		</property>
		<property name="hibernateProperties">
			<props>
				<prop key="hibernate.show_sql">true</prop>
				<prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
				<prop key="transaction.factory_class">org.hibernate.transaction.JDBCTransactionFactory</prop>
				<prop key="current_session_context_class">thread</prop>
			</props>
		</property>
	</bean>

	<bean id="bookServiceDAO" class="com.springbookstore.data.BookServiceDAOImplementation">
		<property name="sessionFactory" ref="sessionFactory" />
	</bean>

Finally, am I correct to assume that my DAO bean will be injected with the same Hibernate Session Factory object?

I started programming about six months ago, so I'm still a little shaky on using documentations to solve all of my problems. As such, if you could point to a place where I could have found a solution to this particular problem, I would greatly appreciate it.

Thank you so much for your help.

You want to use annotations thus use the AnnotationSessionFactoryBean. Next Don't mess around with the transaction.factory_class and current_session_context_class (unless you use JTA!).

I also suggest a read of the reference guide especially the hibernate section it is pretty clear and consise.
