7.测试
/** * 测试departmentMapper * 建议使用spring的单元测试 可已自动注入 */ @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(locations = {"classpath:applicationContext.xml"}) public class MapperTest { @Autowired DepartmentMapper departmentMapper; @Test public void testCRUD() { /*//1、创键IOC容器 ApplicationContext ioc = new ClassPathXmlApplicationContext("applicationContext.xml"); //2、IOC容器中取出mapper ioc.getBean(DepartmentMapper.class);*/ System.out.println(departmentMapper); } }
