MockMvc: forwardedUrl is null

我在使此测试工作时遇到问题。断言总是失败，因为它无法验证始终为空的转发 URL。如果我删除此假设，它将无法验证返回模型。我想这是由于缺少转发的 URL。我的测试类如下所示：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"classpath:test-application-config.xml"})
@WebAppConfiguration
public class UserControllerTest {
  private MockMvc mockMvc;
  @Mock
  private UserService userServiceMock;
  @Inject 
  private WebApplicationContext wac;
  @Before
  public void setUp() {
    MockitoAnnotations.initMocks(this);
    mockMvc = MockMvcBuilders.webAppContextSetup(wac).build();
  }
  @Test
  public void users_ShouldAddUserEntriesToModelAndRenderUserListView() throws Exception {
    User firstUser = generateSampleUser("Pera", "Peric");
    User secondUser = generateSampleUser("Maja", "Majic");
    when(userServiceMock.getAllUsers()).thenReturn(Arrays.asList(firstUser, secondUser));
    mockMvc.perform(get("/users"))
         .andExpect(status().isOk())
         .andExpect(view().name("users"))
         .andExpect(forwardedUrl("/WEB-INF/velocity/users.vm"))
         .andExpect(model().attribute("users", hasSize(2)))
         .andExpect(model().attribute("users", hasItem(
                 allOf(
                         hasProperty("id", is(1L)),
                         hasProperty("firstName", is("Pera")),
                         hasProperty("LastName", is("Peric"))
                 )
         )))
         .andExpect(model().attribute("users", hasItem(
                 allOf(
                         hasProperty("id", is(2L)),
                         hasProperty("firstName", is("Maja")),
                         hasProperty("LastName", is("Majic"))
                 )
         )));
    verify(userServiceMock, times(1)).getAllUsers();
    verifyNoMoreInteractions(userServiceMock);
  }
  private User generateSampleUser(String firstName, String lastName) {
    User user = new User();
    user.setFirstName(firstName);
    user.setLastName(lastName);
    user.setEmail("test@email.com");
    user.setBirthday(new Date());
    user.setGender(Gender.MALE);
    user.setPersonalNumber("1234567890123");
    return user;
  }
}

测试配置文件如下所示：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"

    <property name="suffix" value=".vm" />
    <property name="exposeSessionAttributes" value="true" />
</bean>

我

必须指出，我只是春季 mvc 的初学者，我不熟悉控制器测试。

编辑：我忘了添加用户控制器实现：

   @Controller
public class UserController {
    @Inject
    private UserService userService;
    @RequestMapping(value = "/users", method = RequestMethod.GET)
    public ModelAndView getAllUsers() {
        List<User> users = userService.getAllUsers();
        return new ModelAndView("users", "users", users);
    }
}

编辑：这是导致此问题的异常的完整堆栈跟踪：

如果您使用生产配置文件而不是test-application-config，它是否有效？

例如

@ContextConfiguration({"file:src/main/webapp/WEB-INF/applicationContext.xml", 
     "file:src/main/webapp/WEB-INF/dispatcher-servlet.xml"})

也许您需要在resourceLoaderPath中添加一些../.

例如

<property name="resourceLoaderPath" value="../main/webapp/WEB-INF/velocity/" />
