Java – how to use mockmvc to pass the @ requestbody parameter of the controller

Parameters with @ requestparam annotation can use: Post ("/ ************************************************************ Param ("variable", "value") pass

But how do I pass parameter values with the @ requestbody annotation?

My test method is:

@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());

    }

The controller method being tested is:

@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);
        }

The error I get is: how do I pass the simulated value of the voucher here?

Solution

A post request usually passes its parameters in its body So I can't understand your expectations by providing parameters and content in the same request

So here, you can simply do:

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

If you need to pass the parameter "username = aricloud_admin", add it to the JSON string or explicitly pass it as a query string:

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