spring-mvc – 从WebApplicationContext创建MockMvc和从Controller实例创建MockMvc之间的区别?

当我使用类似于此的WebApplicationContext使用spring MVC 3.2.3为restful-webservice测试创建MockMvc时:

@Autowired
private WebApplicationContext wac;

private MockMvc mockMvc;

@Before
public void setup() {
    this.mockMvc = MockMvcBuilders.webAppContextSetup(this.wac).build();
}


// ...

}

然后当我运行我的测试时,它将失败并返回代码404并且我的日志说明了

Did not find handler method for [my/path]

但如果我改变这种方式

public class MyWebTests {

private MockMvc mockMvc;

@Before
public void setup() {
    this.mockMvc = MockMvcBuilders.standaloneSetup(new AccountController()).build();
}

// ...

}

然后我的测试运行良好,没有任何错误.

我知道的唯一区别是,如果我使用WebApplicationContext创建MockMvc然后它将加载我的Spring Confuguration,而如果我使用Controller然后它不会.

在我的情况下,什么可能导致该错误(没有找到处理程序方法…)?

我的考试班

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("classpath:restful-test-context.xml")
@WebAppConfiguration
public class TestSourceController {
@Autowired
private WebApplicationContext wac;

private MockMvc mockMvc;
private ObjectMapper mapper;

@Autowired
DeviceDAO deviceDAO;

@AfterClass
public static void tearDownAfterClass() throws Exception {
}

@Before
public void setUp() throws Exception {
    Mockito.reset(deviceDAO);
    mockMvc = MockMvcBuilders.standaloneSetup(new SourceController()).build();
    mapper = new ObjectMapper();
}

@After
public void tearDown() throws Exception {
}

@Test
public void testGetAllDevice() throws UnsupportedEncodingException,
        Exception {
    Device device1 = new Device();
    device1.setId("switch1");
    device1.setIsRoot(true);
    device1.setName("switch1");
    device1.setStatus("ONLINE");
    device1.setType("SWITCH");

    Device device2 = new Device();
    device2.setId("switch2");
    device2.setIsRoot(true);
    device2.setName("switch2");
    device2.setStatus("OFFLINE");
    device2.setType("SWITCH");

    List<Device> devices = Arrays.asList(device1, device2);

    when(deviceDAO.getAllDevices()).thenReturn(devices);

    String expected = mapper.writeValueAsString(devices);

    String result = mockMvc
            .perform(get("/api/devices").accept(MediaType.APPLICATION_JSON))
            .andExpect(status().isOk()).andReturn().getResponse()
            .getContentAsString();

    verify(deviceDAO).getAllDevices();

    assertEquals(expected, result);
}

}

我的控制器

@Controller
public class SourceController {

private static final Logger logger = LoggerFactory.getLogger("SourceController");

@RequestMapping(value = "/api/devices", method = RequestMethod.GET)
@ResponseBody
public List<Device> getAllDevice() {
    DeviceDAO deviceDAO = AppContext.getService(DeviceDAO.class,
            "deviceDAO");
    logger.info("The deviceDAO is" + deviceDAO.toString() + "!");
    return deviceDAO.getAllDevices();
}
}

最佳答案
MockMvc期望Controller类初始化.看看我是如何做到这一点的.

@InjectMocks
private SampleController controller = new SampleController();
@Before
public void before() {
    MockitoAnnotations.initMocks(this);
    this.mockMvc = MockMvcBuilders.webAppContextSetup(this.wac)
            .dispatchOptions(true).build();


}
