spring的restTemplate工具类

 
  public static String doPost(String url, Object paramMap, String description) {
    log.info("{} 请求参数： {}", description, paramMap.toString);
    log.info("{} 请求url： {}", description, url);
    HttpHeaders headers = new HttpHeaders();
    headers.setContentType(MediaType.APPLICATION_JSON_UTF8);
    HttpEntity httpEntity = new HttpEntity<>(paramMap, headers);
    ResponseEntity response = restTemplate.postForEntity(url, httpEntity, String.class);
    log.info("{} 返回信息： {}", description, response);
    return response.getBody();
  }

  
  public static String doGetRequest(String url) {
    RestTemplate restTemplate = new RestTemplate();
    ResponseEntity response = restTemplate.getForEntity(url, String.class);
    return response.getBody();
  }
