我正在尝试在CourseServiceImpl的courseDao字段中添加模拟对象,但无法正常工作。
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(
locations = {"file:src/main/webapp/WEB-INF/config/servlet-config.xml"}
)
@ActiveProfiles("test")
public final class CourseServiceTest {
@Mock
private CourseDao courseDao;
@Autowired
private CourseService courseService;
@Before
public void setUp() {
MockitoAnnotations.initMocks(this);
}
@Test
public void testCourseServiceNotNull() {
assertNotNull(courseService);
assertNotNull(courseDao);
ReflectionTestUtils.setField(courseService, "courseDao", courseDao, CourseDao.class);
}
反射语句引发错误,未找到字段“courseDao”。但是,当我使用new运算符创建对象时,它可以正常工作。
ReflectionTestUtils.setField(new CourseServiceImpl(), "courseDao", courseDao, CourseDao.class);

CourseServiceImpl
@Service(value = "courseService")
@Transactional(readOnly = false, propagation = Propagation.REQUIRES_NEW)
public class CourseServiceImpl implements CourseService {
@Autowired
private MessageSource messageSource;
@Autowired
private CourseDao courseDao;
@Autowired
private ApplicationContext context;
请指教。
最佳答案
您的CourseServiceImpl
类具有@Transactional
批注,这意味着在将Beant实例作为依赖项注入"Transactional"
以及Spring上下文中的所有其他bean之前,用CourseServiceTest
代理包装的bean实例。这样的代理实例会隐藏原始private
实例的所有CourseServiceImpl
字段。
因此,由于注入的courseService
实例不再是原始CourseServiceImpl
类,而是动态cglib
或JDK
代理类,因此您无法访问所需的字段。
