java.lang.AssertionError：沒有使用的ModelAndView發現webAppContextSetup

Question

我想測試此控制器：

@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"; 

    } 


} 

請注意RequestMapping。所以這是我的JUnit測試：

@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; 
    } 

} 

調度員-servlet.xml中包含在其中控制器在封裝組件掃描當我手動測試控制器，一切工作正常。

所以第一個測試（editTestView（））返回綠色。但第二個失敗，此錯誤：

我不明白，爲什麼get("/bookmanagement/edit?id=58385d39bd7f3513c83faa65")呼叫另一方面不會正常工作，但fileUpload("/bookmanagement/fileUpload")。

我在這裏錯過了什麼？

Answer 1

它失敗的原因，

預期的文件名是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 { 

但是你逝去的名稱爲json，

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

你需要修復的，

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

另請檢查處理程序方法的其他必需參數。
