Data Access - Spring Enterprise Recipes: A Problem Solution Approach - page 151

In the bean configuration file for Hibernate (i.e., beans-hibernate.xml ), you have to declare
a HibernateTransactionManager instance for this application and enable declarative transaction
management via <tx:annotation-driven> .

<beans xmlns=" http://www.springframework.org/schema/beans"
xmlns:xsi=" http://www.w3.org/2001/XMLSchema-instance"
xmlns:tx=" http://www.springframework.org/schema/tx"
xsi:schemaLocation=" http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx-3.0.xsd">
...
<tx:annotation-driven />

<bean id="transactionManager"
class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory" />
</bean>

<bean name="courseDao"
class="com.apress.springenterpriserecipes.course.hibernate.

➥

HibernateCourseDao">
<property name="sessionFactory" ref="sessionFactory" />
</bean>
</beans>
Remember that HibernateTemplate will translate the native Hibernate exceptions into exceptions
in Spring's DataAccessException hierarchy. This allows consistent exception handling for different data
access strategies in Spring. However, when calling the native methods on a Hibernate session, the
exceptions thrown will be of native type HibernateException . If you want the Hibernate exceptions to
be translated into Spring's DataAccessException for consistent exception handling, you have to apply
the @Repository annotation to your DAO class that requires exception translation.

package com.apress.springenterpriserecipes.course.hibernate;
...
import org.springframework.stereotype.Repository;

@Repository
public class HibernateCourseDao implements CourseDao {
...
}

Then register a PersistenceExceptionTranslationPostProcessor instance to translate the native
Hibernate exceptions into data access exceptions in Spring's DataAccessException hierarchy. This bean
post processor will only translate exceptions for beans annotated with @Repository .

<beans ...>
...
<bean class="org.springframework.dao.annotation. ➥

PersistenceExceptionTranslationPostProcessor" />
</beans>
