预期状态：<200> 但为：<400> MockMvc 错误

Question

我在测试我的 Spring 引导控制器时遇到了问题，我在过去几个小时里一直在努力解决这个问题。我对编码很陌生，但我还是在公司得到了那个任务。

我的控制器：

@GetMapping(value = "/data", produces = MediaType.APPLICATION_JSON_VALUE)
    public ResponseEntity<Object> getData(@RequestParam("core") List<String> core, @RequestParam("date") List<String> date,
        @RequestParam("state") String state, @RequestParam("area") List<String> area,
        @RequestParam("type") List<String> type, @RequestParam("analyt") String analyt,
        @RequestParam("wp") String wp, @RequestParam("subDesc") String subDesc,
        @RequestParam("anaMonitor") List<String> anaMonitor, @RequestParam("ecoMonitor") List<String> ecoMonitor,
        @RequestParam("subType") List<String> subType, @RequestParam("needed") List<String> needed,
        @RequestParam("notify") List<String> notify, @RequestParam("available") List<String> available,
        @RequestParam("phase") List<String> phase, @RequestParam("subAvailable") List<String> subAvailable,
        @RequestParam("subShipped") List<String> subShipped, @RequestParam("external") List<String> external,
        @RequestParam("valid") List<String> valid, @RequestParam("contract") List<String> contract) {
    FilterInputModel model = new FilterInputModel(core, date, state, type, area, analyt, wp, subDesc, anaMonitor, ecoMonitor, subType, needed, notify, available, phase, subAvailable, subShipped, external, valid, contract);  
        return new ResponseEntity<>(vaultService.getFilteredFields(model), HttpStatus.OK);
    }

这里有一个测试：

@DisplayName("Controller Test")
@AutoConfigureMockMvc
@WebMvcTest(controllers = Controller.class, excludeAutoConfiguration = SecurityAutoConfiguration.class)
class ControllerTest {

    @Autowired
    private MockMvc mockMvc;
    
    private FilterInputModel model;
    
    @MockBean
    private TestService testService;
    
    @Autowired
    ControllerTest() {
    }

    @BeforeEach
    void setup() {
        MockitoAnnotations.openMocks(this);
        
    @Test
    void getDataTest() throws Exception {
        List<Object> response = new ArrayList<>();
        when(vaultService.getFilteredFields(model))
            .thenReturn(response)
            .thenReturn(HttpStatus.OK);
            
        this.mockMvc.perform(
                MockMvcRequestBuilders.get("/api/data")
                    .contentType(MediaType.APPLICATION_JSON_VALUE)
                    .accept("application/json"))
                .andExpect(MockMvcResultMatchers.status().isOk());
                .andExpect(result -> assertEquals(response, result.getAsyncResult()));
   }

这是我得到的答案。它在一条错误消息中说“方法参数类型列表的必需请求参数 'core' 不存在”，但这个答案对我帮助不大。我仍然在寻找答案。

MockHttpServletRequest:
      HTTP Method = GET
      Request URI = /api/data
       Parameters = {}
          Headers = [Content-Type:"application/json;charset=UTF-8", Accept:"application/json"]
             Body = null
    Session Attrs = {}

Handler:
             Type = hr.ogcs.ltt.api.lttapi.controller.LttController
           Method = hr.ogcs.ltt.api.lttapi.controller.LttController#getData(List, List, String, List, List, String, String, String, List, List, List, List, List, List, List, List, List, List, List, List)

Async:
    Async started = false
     Async result = null

Resolved Exception:
             Type = org.springframework.web.bind.MissingServletRequestParameterException

ModelAndView:
        View name = null
             View = null
            Model = null

FlashMap:
       Attributes = null

MockHttpServletResponse:
           Status = 400
    Error message = Required request parameter 'core' for method parameter type List is not present
          Headers = [Vary:"Origin", "Access-Control-Request-Method", "Access-Control-Request-Headers"]
     Content type = null
             Body = 
    Forwarded URL = null
   Redirected URL = null
          Cookies = []

您没有向该方法发送所需的参数（用 @RequestParam 注释的参数）。默认情况下，它们都是必需的。如果不存在 Spring 会阻止缺少参数的请求。

发送参数示例：

mvc.perform(
    MockMvcRequestBuilders.get("/public/xpto/{code}", "21212").param("core", "ubababacaio")
        .contentType(MediaType.APPLICATION_JSON)
        .contentType(MediaType.APPLICATION_JSON_VALUE).characterEncoding("UTF-8")).andExpect(status().isOk());
