java.lang.AssertionError : No ModelAndView found using webAppContextSetup

Question

我想测试这个 Controller :

@Controller
@RequestMapping(value = "/bookmanagement")
public class BookManagementController {

    @RequestMapping(value = "")
    public String bookManagement(HttpSession session, HttpServletRequest request, Model model, Authentication auth) {

        // does stuff
        return "bookManagement";
    }

    @RequestMapping(value = "edit")
    public String edit(HttpSession session, HttpServletRequest request, Model model, Authentication auth,
            @RequestParam(value = "id", required = true) String id) {

        // does stuff

        return "editBook";
    }

    @RequestMapping(value = "fileUpload", method = RequestMethod.POST)
    public String fileUpload(@RequestParam("coverFile") MultipartFile file,
            @RequestParam(value = "type", required = true) String type,
            @RequestParam(value = "id", required = true) String id,
            @RequestParam(value = "pages", required = true) String pages, HttpServletResponse response, Model model)
            throws JSONException {

        // writes file

        return "editBook_File";

    }


}

请注意RequestMapping。这是我的 JUnit 测试:

@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration("file:application/webapp")
@ContextConfiguration("file:application/webapp/WEB-INF/dispatcher-servlet.xml")
public class BookManagementControllerTest {

    private MockMvc mockMvc;

    @Autowired
    private UsersRepository usersCollection;

    @Resource
    private FilterChainProxy springSecurityFilterChain;

    @Resource
    private WebApplicationContext webApplicationContext;

    private MockHttpSession session;

    @InjectMocks
    private BookManagementController bookManagementController;

    @Before
    public void setup() {

        MockitoAnnotations.initMocks(this);

        this.mockMvc = MockMvcBuilders.webAppContextSetup(webApplicationContext)
                .addFilter(springSecurityFilterChain)
                .build();

        this.session = getSessionWithAuthentication();

    }

    @Test
    public void editTestView() throws Exception {

        this.mockMvc.perform(get("/bookmanagement/edit?id=58385d39bd7f3513c83faa65").session(session))
                .andExpect(view().name("editBook")).andExpect(status().isOk()).andReturn();

    }

    @Test
    public void uploadCoverFile() throws Exception {

        MockMultipartFile jsonFile = new MockMultipartFile("json", "", "application/json",
                "{\"json\": \"someValue\"}".getBytes());

        mockMvc.perform(MockMvcRequestBuilders.fileUpload("/bookmanagement/fileUpload").file(jsonFile))
                .andExpect(view().name("editBook_File")).andExpect(status().isOk()).andReturn();

    }

    private MockHttpSession getSessionWithAuthentication() {
        Users testPodUser = usersCollection.findByEmail("test@pod.de");
        SecUserDetails principal = new SecUserDetails(testPodUser);
        SecurityContext secContext = SecurityContextHolder.getContext();
        secContext.setAuthentication(new UsernamePasswordAuthenticationToken(principal, principal.getPassword(),
                principal.getAuthorities()));

        MockHttpSession session = new MockHttpSession();
        session.setAttribute(HttpSessionSecurityContextRepository.SPRING_SECURITY_CONTEXT_KEY, secContext);

        return session;
    }

}

dispatcher-servlet.xml 包含 Controller 所在包中的组件扫描。当我手动测试 Controller 时，一切正常。

因此第一个测试 (editTestView()) 返回绿色。但第二个失败并出现以下错误:

我不明白为什么 get("/bookmanagement/edit?id=58385d39bd7f3513c83faa65") 调用工作正常，但 fileUpload("/bookmanagement/fileUpload") 另一方面则不会。

我在这里缺少什么？

Answer 1

它失败了，因为，

文件的预期名称为coverFile，

@RequestMapping(value = "fileUpload", method = RequestMethod.POST)
    public String fileUpload(@RequestParam("coverFile") MultipartFile file,
            @RequestParam(value = "type", required = true) String type,
            @RequestParam(value = "id", required = true) String id,
            @RequestParam(value = "pages", required = true) String pages, HttpServletResponse response, Model model)
            throws JSONException {

但是您将名称作为 json 传递，

MockMultipartFile jsonFile = new MockMultipartFile("json", "", "application/json",
                "{\"json\": \"someValue\"}".getBytes());

您需要将其修复为，

MockMultipartFile jsonFile = new MockMultipartFile("coverFile", "", "application/json",
                    "{\"json\": \"someValue\"}".getBytes());

还要检查处理程序方法的其他必需参数。
