SpringMvc HttpClient上传参数

SpringMVC代码示例如下：

   @RequestMapping(value = "doSendMessageServer",method=RequestMethod.POST, consumes="application/json")
    @ResponseBody
    public EasyResult doSendMessageServer(@RequestBody JSONObject jsonObject,HttpServletRequest request) {
     
     
     String userkey=(String)jsonObject.get("userkey");
     String content=(String)jsonObject.get("content");
     
     String requestStr = GsonUtils.toJson(userkey) + GsonUtils.toJson(content);
        logger.info("发送消息。req：" + requestStr);
        try {
         ChannelUser channelUser=null;
         
         ChannelId channelId=CacheChannelUser.userkeyChannelId.get(userkey);
            if(channelId!=null){
             // 查找对应id的channel
              channelUser=CacheChannelUser.cacheChannel.get(channelId.toString());
//              channelUser=CacheChannelUser.cacheChannel.get(userkey);
              if (null != channelUser) {
                  
                  //test
                  itstack.demo.netty.server.pojo.Result result=new itstack.demo.netty.server.pojo.Result();
                  result.setContent(content);
                  result.setStatus(1);
                  result.setType(Global.SEND_SERVER_HANDLE_MSG);
                  
                  TextWebSocketFrame tws = new TextWebSocketFrame(JSONObject.toJSONString(result));
                  channelUser.getChannel().writeAndFlush(tws);
                  
                 } else {
                     return EasyResult.buildErrResult("对方已经下线");
                 }
            }
          
            return EasyResult.buildSuccessResult();
        } catch (Exception e) {
            logger.info("发送消息失败。req：" + requestStr, e);
            return EasyResult.buildErrResult(e);
        }
    }

Client代码示例如下：

 public static void main(String[] args) {
  
   try {
    NettyClient client=new NettyClient();
    client.testHttpclient("1111111111");
//    client.connect("192.168.3.128", 7398);
   } catch (Exception e) {
    e.printStackTrace();
   }
  
 }
 
 
 public void testHttpclient(String userkey){
  
  JSONObject jsonParam=new JSONObject();
  jsonParam.put("userkey", userkey);
  jsonParam.put("content", "这是内容");
  String url="http://192.168.31.199:8080/itstack-demo-netty-server-web/socketServerController/doSendMessageServer.do";
  try {
   HttpClientUtil.httpPost(url, jsonParam);
//   HttpClientUtil.doGet(url+"?userkey=1212&content=12312","UTF-8");
  } catch (Exception e) {
   e.printStackTrace();
  }
  
 }
