resttemplate use post simultaneously submit formData and body data

Resttemplate submitted online are many ways to use the time when constructing HttpEntity objects, or use the following method

1 String jsonData = JSON.toJSONString(vo);
2         HttpHeaders headers = new HttpHeaders();
3         headers.setContentType(MediaType.APPLICATION_JSON);
4         HttpEntity<String> request = new HttpEntity<>(jsonData, headers);

ResponseEntity<JSONObject> responseEntity = restTemplate.postForEntity(url, request, JSONObject.class);

This method appears in the body json body inside

 

Another embodiment of the method filed formdata construct a map as follows:

        MultiValueMap<String, String> map = new LinkedMultiValueMap<>();
        map.add("method", UPLOAD_METHOD);
        map.add("timestamp", timestamp + "");
        map.add("sign", SIGN);
        map.add("companyNo", companyNo);
        HttpHeaders headers = new HttpHeaders();
        HttpEntity<String> request = new HttpEntity<>(map , headers);
        ResponseEntity<JSONObject> responseEntity = restTemplate.postForEntity(url, request, JSONObject.class);

In fact, in three post submission stuff in it 

header 

query  

body

The springboot in fromdata is (other frameworks uncertain) may be submitted as part of the query

as follows

        MultiValueMap<String, String> map = new LinkedMultiValueMap<>();
        map.add("method", UPLOAD_METHOD);
        map.add("timestamp", timestamp + "");
        map.add("sign", SIGN);
        map.add("companyNo", companyNo);
        HttpHeaders headers = new HttpHeaders();
        headers.setContentType(MediaType.APPLICATION_JSON);
        HttpEntity<String> request = new HttpEntity<>(jsonData, headers);
        UriComponentsBuilder builder = UriComponentsBuilder.fromHttpUrl(apiURL).queryParams(map);
        ResponseEntity<JSONObject> responseEntity = restTemplate.postForEntity(builder.toUriString(), request, JSONObject.class);

The map constructed using UriComponentsBuilder inside url
