Unit testing SpringMVC测试MVC方法

我在控制器中有一个方法：

@RequestMapping(value = "/", method = RequestMethod.GET)
public final String mainGet(final HttpServletRequest request,
        final HttpServletResponse response, ModelMap model)
        throws ServletException {

    model.addAttribute("fontSize", fontSize);
    courses = persistenceServices.getCourses();
    model.addAttribute("coursesList", courses);

    return "home";
}

我写了一个简单的测试：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "classpath:tests.xml" })
@WebAppConfiguration
public class TestHomeController {

    @Autowired
    private WebApplicationContext wac;
    private MockMvc mockMvc;

    @Mock
    private PersistenceServices persistenceServicesMock;

    @InjectMocks
    private HomeController homeController;

    @Before
    public void setup() {
        MockitoAnnotations.initMocks(this);
        this.mockMvc = MockMvcBuilders.standaloneSetup(homeController).build();
    }

    @Test
    public void testMainGet() throws Exception {
        mockMvc.perform( get("/")).andExpect(status().isOk()).andExpect(view().name("home"));

        verify(persistenceServicesMock, times(1));
        verifyNoMoreInteractions(persistenceServicesMock);
    }

一切似乎都很好，但我不能调用任何MvcMock的方法。Eclipse在所有这些内容（执行、状态、视图等）下面加下划线，并向我显示以下信息：

The method perform(RequestBuilder) in the type MockMvc is not applicable for the arguments (MockHttpServletRequestBuilder)

我尝试将参数转换为RequestBuilder和ResultMatcher，但没有成功。

尝试将

import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get;
import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.post;

---

您是否静态导入get、状态、视图等？是的，我有类似的内容：导入静态org.springframework.test.web.servlet.request.MockMvcRequestBuilders.*；导入静态org.springframework.test.web.servlet.result.MockMvcResultMatchers.*；删除wac声明。因为您使用的是独立设置，所以不需要它。另外，MockitoAnnotations.initMocks（this）；应该在mockMVCbuilder之后调用。好的，我删除了wac。当我在mockMVCbuilder之后调用MockitoAnnotations.initMocks（this）时，我有NullPointerException。如果我在mockMVCbuilder之前有MockitoAnnotations.initMocks（此），我有一个错误：MockHttpServletRequestBuilder无法强制转换为RequestBuilder。NullPointer是因为您尚未初始化控制器。声明为：private HomeController HomeController=new HomeController（）；
