java.lang.AssertionError:预期状态:<200>但是:<405>

Question

我有一个标记为类的方法 @Controller

@RequestMapping(value = "/addEvent", method = RequestMethod.POST)
    public String addEvent(Model model,
            @Valid @ModelAttribute("myEvent") Event event,
            BindingResult result, RedirectAttributes redirectAttributes,
            @RequestParam(required = true) Integer selectedEventTypeId,
            @RequestParam(required = true) Integer selectedEventStatusId) {

        if (result.getErrorCount() > 1 ){
            return "eventDetailsAdd";
        }
        eventService.addEvent(event, selectedEventTypeId, selectedEventStatusId);
        redirectAttributes.addAttribute("idEvent", event.getId());
        redirectAttributes.addAttribute("message", "added correctly at " + new Date() );
        return "redirect:eventDetails";
    }

如果我写下面的代码:

MockHttpServletRequestBuilder request = MockMvcRequestBuilders
                .get("/addEvent");
        ResultActions result = mockMvc.perform(request);

        result.andExpect(MockMvcResultMatchers.status().isOk());

我知道了:

java.lang.AssertionError: Status expected:<200> but was:<405>
    at org.springframework.test.util.AssertionErrors.fail(AssertionErrors.java:60)
    at org.springframework.test.util.AssertionErrors.assertEquals(AssertionErrors.java:89)
    at org.springframework.test.web.servlet.result.StatusResultMatchers$5.match(StatusResultMatchers.java:549)
    ...

有什么问题,我该如何解决？

UPDATE

如果我写:

MockHttpServletRequestBuilder request = MockMvcRequestBuilders
                .get("/addEvent");
        request.param("selectedEventTypeId", "1");
        request.param("selectedEventStatusId", "1");

        ResultActions result = mockMvc.perform(request);

        result.andExpect(MockMvcResultMatchers.status().isOk());
        result.andExpect(MockMvcResultMatchers.forwardedUrl("eventDetailsAdd"));

我看到了同样的结果.

解决

Bitman建议+添加(由Sotirios Delimanolis提供)

   request.param("selectedEventTypeId", "1");
   request.param("selectedEventStatusId", "1");

在我的案例中,Event事件实例将从Spring中获取什么？

Answer 1

改变这个

MockHttpServletRequestBuilder request = MockMvcRequestBuilders
            .get("/addEvent");

至

MockHttpServletRequestBuilder request = MockMvcRequestBuilders
                .post("/addEvent");

因为你期望method = RequestMethod.POST在控制器中发布POST但是你的测试正在执行GET.

这是HTTP错误405方法不允许的意思
