Migrating application context configuration to Spring 3.1 and Hibernate 4.0

Question

I'm having hard time finding migration docs. I was using sping 3.0.5 and hibernate 3.4.

I migrated to the latest release candidates: spring 3.1 and hibernate 4.0

I was able to refactor my classes without problem but the application context for hibernate is giving me problems since I have not see any examples on how to configure it.

Specifically:

<bean id="sessionFactory"    class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
    <property name="dataSource" ref="dataSource"/>
    <property name="mappingResources">
        <list>...</list>
   </property>
    <property name="hibernateProperties">
        <props>
          ... 
          <prop key="hibernate.connection.provider_class">org.hibernate.service.jdbc.connections.internal.C3P0ConnectionProvider</prop>
          <prop key="hibernate.cache.provider_class">????</prop>
          ...
        </props>
    </property>
</bean>

Apparently properties dataSource , mappingResources and hibernateProperties no longer exist and I'm not so sure about what to put in hibernate.connection.provider_class and hibernate.cache.provider_class .

And I keep getting:

Caused by: java.lang.ClassNotFoundException: org.hibernate.engine.FilterDefinition

at application start.

Answer 1

To my knowledge, Spring has no support for Hibernate 4. If it did, I'd expect to see an org.springframework.orm.hibernate4 package in the 3.1.x package list , but it's not there. I don't believe I've seen any mention of it in any release notes or anything, either.

In other words, Spring is working fine, but you're using an incompatible version of Hibernate.

Answer 2

dataSource still exists, based on the JavaDoc for LocalSessionFactoryBean . See the section at the very top; it has an example config with a dataSource property. mappingResources also exists.

The Spring 3.1 reference guide also has an example, with dataSource and mappingResources .

Hibernate 4 does not have a ref guide yet.
