这里有童鞋会发现为啥还添加了
hibernate的jar包啊，其实这里不是用的hibernate而是用的hibernate的相关实现,贴个图大家就看懂了 由于不同的orm框架之间有区别，spring Data Jpa可以方便的在不同的orm中间进行切换

BaseReposity.class
@NoRepositoryBean
public interface BaseReposity extends JpaRepository,JpaSpecificationExecutor{
}
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 {
}
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
