spring - 春のjpaエンティティの自動スキャンパッケージ

Question

hibernate SessionFactoryを使用すると、これを簡単に行うことができます。

<bean id="sessionFactory"
...
p:packagesToScan="com.sahandrc.survey" 

jpa EntityManagerFactoryでそれを行うにはどうすればよいですか？

Answer 1

それ以上の場合もほぼ同じSpring 3.1です。

ここに例があります：

<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"
            p:packagesToScan="com.sahandrc.survey"
            p:dataSource-ref="dataSource"
            p:jpaPropertyMap-ref="jpaPropertyMap"
            p:jpaVendorAdapter-ref="hibernateVendor" />
