java - How to auto detect entities in JPA 2.0 -


i pretty sure used sort of auto detection of beans annotated @entity in jpa 2.0 in past not able find out how. how do instead of listing each bean in class xml element in persistence.xml?

since spring 3.1, have option forget persistence.xml altogether, , configure entitymanagerfactory using packagestoscan property, similar this:

<bean id="entitymanagerfactory"        class="org.springframework.orm.jpa.localcontainerentitymanagerfactorybean"       p:datasource-ref="datasource"       p:packagestoscan="${jpa.entity.packages}">      <property name="jpavendoradapter">         <bean class="org.springframework.orm.jpa.vendor.hibernatejpavendoradapter"               p:showsql="${hibernate.show_sql}"/>     </property>      <property name="jpaproperties">         <props>             <prop key="hibernate.format_sql">${hibernate.format_sql}</prop>             <prop key="hibernate.hbm2ddl.auto">${hibernate.hbm2ddl.auto}</prop>         </props>     </property> </bean>
