spring data jpa 问题，关于实现接口方面的

Rels 2014-09-05 05:54:59
1、这个是jpa配置，其中配置了repository-impl-postfix="Impl" 这一项。


<jpa:repositories base-package="com.nk"

		repository-impl-postfix="Impl" entity-manager-factory-ref="entityManagerFactory"

		transaction-manager-ref="transactionManager"></jpa:repositories>


2、接口


public interface PermissionDao extends PagingAndSortingRepository<Permission, Integer>{



	/* 方法的实现由PermissionDaoImpl完成 */

	List<Permission> findByEmployeeId(Integer employeeId);

}

3、实现，由于sql比较复杂，由mybatis实现。
 

public class PermissionDAOImpl extends BaseDaoImpl<Permission> {

	

	public PermissionDAOImpl(){

		super(Permission.class);

	}

	

	/* 实现的是接口中的方法 */

	public List<Permission> findByEmployeeId(Integer employeeId){

		Map<String, Object> params = new HashMap<String, Object>();

		params.put("employeeId", employeeId);

		return super.sqlSession.selectList(super.entityMapper+"findByEmployeeId", employeeId);

	}

}


结果：
项目启动时报错：

说是我的Permission实体中没有那个属性，我的实体中确实没有，可是我由impl实现的。
现在我想用impl去实现这个方法，该怎么处理？

public class MyRepositoryImpl<T, ID extends Serializable>
  extends SimpleJpaRepository<T, ID> implements MyRepository<T, ID> {

  private EntityManager entityManager;

  // There are two constructors to choose from, either can be used.
  public MyRepositoryImpl(Class<T> domainClass, EntityManager entityManager) {
    super(domainClass, entityManager);

    // This is the recommended method for accessing inherited class dependencies.
    this.entityManager = entityManager;
  }

  public void sharedCustomMethod(ID id) {
    // implementation goes here
  }
}
建议从Simple类继承实现类
