Spring with Hibernate configuration

Loads object from the data source

<bean id="someRepository">

    <property name="sessionFactory" ref="sessionFactory"/>

</bean>

Instructs the container to look for beans with @Transactional and decorate them

<tx:annotation-driven transaction-manager="transactionManager"/>

A Hibernate SessionFactory for mapping entities from object to relation tables

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">

   <property name="dataSource" ref="dataSource"/>

   <property name="annotatedClasses">

      <list>

         <value>package.Entity1</value>

         <value>package.Entity2</value>

      </list>

   </property>

   <property name="hibernateProperties">

      <value>

         hibernate.format_sql=true

         hibernate.show_sql=true

      </value>

   </property>

</bean>

A transaction manager for working with Hibernate SessionFactories

<bean id="transactionManager"  

    class="org.springframework.orm.hibernate3.HibernateTransactionManager">

    <property name="sessionFactory" ref="sessionFactory" />

</bean>

Transparent Exception Handling

Annotate classes with @Repository

Define a Spring-provided BeanPostProcessor (eg. <context:annotation-config/> or context:component-scan)
