RestTemplate发送中文参数乱码问题

        HttpHeaders headers = new HttpHeaders();    MediaType type = MediaType.parseMediaType("application/json; charset=UTF-8");     headers.setContentType(type);    headers.add("Accept", MediaType.APPLICATION_JSON.toString());                  JSONObject jsonObj = JSONObject.fromObject(params);                 HttpEntity<String> formEntity = new HttpEntity<String>(jsonObj.toString(), headers);         String result = restTemplate.postForObject(url, formEntity, String.class);
