How to configure Spring Data JPA using XML

If you want to configure Spring Data JPA by using XML configuration (and use the configuration described in the book), you have to follow these steps:

1. Configure the data source bean.
2. Configure the entity manager factory bean.
3. Configure the transaction manager bean.
4. Enable annotation driven transaction management.
5. Configure Spring Spring Data JPA.

The application context configuration (applicationContext-persistence.xml) file looks as follows:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xmlns:jpa="http://www.springframework.org/schema/data/jpa"

    repository interfaces

  <jpa:repositories base-package="foo.bar.repository"/>
</beans>
