RoleRepository is

import org.springframework.data.jpa.repository.JpaRepository; import org.wahid.cse.entity.Role;   public interface RoleRepository extends JpaRepository<Role, Integer>{   } 

Answer 1

Spring Data JPA by default looks for an EntityManagerFactory named entityManagerFactory. Check out this part of the Javadoc of EnableJpaRepositories or Table 2.1 of the Spring Data JPA documentation.

That means that you either have to rename your emf bean to entityManagerFactory or change your Spring configuration to:

<jpa:repositories base-package="your.package" entity-manager-factory-ref="emf" />  

(if you are using XML)

or

@EnableJpaRepositories(basePackages="your.package", entityManagerFactoryRef="emf")

(if you are using Java Config)
