如何使用MockMVC传递控制器的@RequestBody参数

Question

带有@RequestParam注释的参数可以使用:post("/******/***").param("variable","value")传递

但是如何传递具有@RequestBody注释的参数值？

我的测试方法是:

@Test
    public void testCreateCloudCredential() throws Exception {

        CloudCredentialsBean cloudCredentialsBean = new CloudCredentialsBean();
        cloudCredentialsBean.setCloudType("cloudstack");
        cloudCredentialsBean.setEndPoint("cloudstackendPoint");
        cloudCredentialsBean.setUserName("cloudstackuserName");
        cloudCredentialsBean.setPassword("cloudstackpassword");
        cloudCredentialsBean.setProviderCredential("cloudstackproviderCredential");
        cloudCredentialsBean.setProviderIdentity("cloudstackproviderIdentity");
        cloudCredentialsBean.setProviderName("cloudstackproviderName");
        cloudCredentialsBean.setTenantId(78);
        cloudCredentialsBean.setCredentialId(98);

        StatusBean statusBean = new StatusBean();
        statusBean.setCode(200);
        statusBean.setStatus(Constants.SUCCESS);
        statusBean.setMessage("Credential Created Successfully");

        Gson gson = new Gson();
        String json = gson.toJson(cloudCredentialsBean);
        ArgumentCaptor<String> getArgumentCaptor =
            ArgumentCaptor.forClass(String.class);
        ArgumentCaptor<Integer> getInteger = ArgumentCaptor.forClass(Integer.class);

        ArgumentCaptor<CloudCredentialsBean> getArgumentCaptorCredential =
            ArgumentCaptor.forClass(CloudCredentialsBean.class);
        when(
            userManagementHelper.createCloudCredential(getInteger.capture(),
                    getArgumentCaptorCredential.capture())).thenReturn(
            new ResponseEntity<StatusBean>(statusBean, new HttpHeaders(),
                HttpStatus.OK));

        mockMvc.perform(
            post("/usermgmt/createCloudCredential").param("username", "aricloud_admin").contentType(
                MediaType.APPLICATION_JSON).content(json)).andExpect(
            status().isOk());

    }

正在测试的控制器方法是:

@RequestMapping(value = "/createCloudCredential", method = RequestMethod.POST, produces = MediaType.APPLICATION_JSON_VALUE, consumes = MediaType.APPLICATION_JSON_VALUE)
    @ResponseBody
    public ResponseEntity<StatusBean> createCloudCredential(
            @RequestParam("userId") int userId,
         @RequestBody CloudCredentialsBean credential) {            
            return userManagementHepler.createCloudCredential(userId, credential);
        }   

我得到的错误是: 如何在此处传递凭证的模拟值？

甲POST请求通常通过它的param在其主体中.所以我无法通过同时给出a param和a content同样的请求来理解你的期望.

所以在这里,你可以简单地做:

    mockMvc.perform(
        post("/usermgmt/createCloudCredential").contentType(
            MediaType.APPLICATION_JSON).content(json)).andExpect(
        status().isOk());

如果需要传递参数"username=aricloud_admin",请将其添加到JSON字符串中,或​​者将其作为查询字符串显式传递:

    mockMvc.perform(
        post("/usermgmt/createCloudCredential?username=aricloud_admin")
            .contentType(MediaType.APPLICATION_JSON).content(json))
            .andExpect(status().isOk());
