   我写过的一个方法 你可参考下    /**
        * @param url 请求地址
        * @param bodyParam 请求体
        * @param headerParam 头部信息
        * @param rClass 返回体类型
        * @param <T> 请求体类型
        * @param <R> 返回体类型
        * @return 返回结果
        */
       public <T, R> R doPost(String url, T bodyParam, Map<String, String> headerParam, Class<R> rClass) {
   
           if (null == rClass || StringUtils.isEmpty(url)) {
               throw new ExecuteFailedResponse("url is empty or restTemplate is null.");
           }
           HttpHeaders requestHeaders = new HttpHeaders();
           if (null != headerParam) {
               headerParam.entrySet().forEach(entrySet -> requestHeaders.add(entrySet.getKey(), entrySet.getValue()));
           }
           HttpEntity<T> requestEntity = new HttpEntity<T>(bodyParam, requestHeaders);
           ResponseEntity<Object> response = restTemplate.exchange(url, HttpMethod.POST, requestEntity, Object.class);
   
           return transforObjet(rClass, response.getBody());
       }
