auto scan packages for jpa entities in spring - spring

Question

One can easily do this when using hibernate SessionFactory:
<bean id="sessionFactory"
...
p:packagesToScan="com.sahandrc.survey"
How can I do that with jpa EntityManagerFactory?

Answer 1

It's almost the same thing for Spring 3.1 and higher.
Here an example :
<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" />
Example with everything in the context file :
