<bean id="itemDaoStore1" class="ItemDaoImpl"> <property name="entityManager"> <bean class = "org.springframework.orm.jpa.support.SharedEntityManagerBean"> <property name = "entityManagerFactory" ref="entityManagerFactory1"/> </bean> </property></bean>
You can provide the persistence unit name in the xml configuration, using the SharedEntityManagerBean, like below:
<bean id="testDao" class="com.test.persistence.dao.BaseDAO"> <property name="entityManager"> <bean class="org.springframework.orm.jpa.support.SharedEntityManagerBean"> <property name="persistenceUnitName" value="persistence-test-unit" /> </bean> </property></bean>of course, you can have the SharedEntityManagerBean as a separate bean
