我想在spring應用程序中測試一個函數。下面是該項目Spring應用程序中的JUnit測試
的結構,這裏是服務類,我想測試
公共類DepartmentServiceImpl實現DepartmentService {
@Autowired
private DepartmentDao departmentDao;
//... other functions
@Override
public Department getDepartment(int depid) {
return departmentDao.getDepartment(depid);
}
}
,這裏是測試單元類,我做
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "sdnext-servlet.xml")
public class TestDepartmentDetails {
Department department = new Department();
DepartmentServiceImpl service = new DepartmentServiceImpl();
@Autowired
private DepartmentDao myDao;
@Test
public void testGetDepartment(){
assertEquals("lalalalalalala", service.getDepartment(98).getDepName());
}
}
但發生異常的是

請注意,即使您成功地掃描了上下文,當您實例化一個全新的「DepartmentServiceImpl」實例時,您的測試也會被破壞,因此Spring不會注入任何依賴項(它們將爲null,從而導致NullPointerException) – kryger
