/**
* {@link EnableAutoConfiguration Auto-configuration} for Spring Data's JPA Repositories.
*
* Activates when there is a bean of type {@link javax.sql.DataSource} configured in the
* context, the Spring Data JPA
* {@link org.springframework.data.jpa.repository.JpaRepository} type is on the classpath,
* and there is no other, existing
* {@link org.springframework.data.jpa.repository.JpaRepository} configured.
*
* Once in effect, the auto-configuration is the equivalent of enabling JPA repositories
* using the {@link org.springframework.data.jpa.repository.config.EnableJpaRepositories}
* annotation.
*
* This configuration class will activate after the Hibernate auto-configuration.
