BaseReposity.class

@NoRepositoryBean
public interface BaseReposity<T,ID extends Serializable> extends JpaRepository<T,ID>,JpaSpecificationExecutor<T>{
}

由于JpaRepository已经有Repository属性了所以我们自己为了不在所有的Jpa类中都写重复的代码所建的接口添加个@NoRepositoryBean声明

BuildingJpa.class

public interface BuildingJpa extends BaseReposity<Building,Long> {
}

BuildingServiceTest.class

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:applicationContext.xml")
public class BuildingServiceTest {

    @Resource
    BuildingJpa buildingJpa;

    @Test
    public void testGetBuildingById() throws Exception {
        System.out.println(" = " );
        Building building=buildingJpa.findOne(111L);


    }
}

注意这里需要使用 findOne() 方法不要使用 getOne() 否则你会发现得到的所有的对象均为空
