java编写http post请求，服务端无法获取post的请求参数（在线等，急）

[wjb44146]

用java编写了http Post的请求代码，如下

public static void submitPost2(String url) {
        HttpClient client = HttpClients. createDefault();
        HttpPost post = new HttpPost(url);

        JSONObject json = new JSONObject();
        json.put("id",1);

        try {
            post.addHeader("Content-type", "application/json; charset=utf-8");
            post.setHeader("Accept", "application/json");
            post.setEntity(new StringEntity(json.toString(), Charset.forName("UTF-8")));
            HttpResponse httpResponse = client.execute(post);

            HttpEntity entity = httpResponse.getEntity();
            System.out.println("status:" + httpResponse.getStatusLine());
            System.out.println("response content:" + EntityUtils.toString(entity));
        } catch (UnsupportedEncodingException e1) {
            e1.printStackTrace();
        } catch (ClientProtocolException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

服务端框架用的SpringBoot搭的SpringMVC,controller的代码如下：

@Controller
@RequestMapping("/clients")
public class ClientsController {

    @Autowired
    private MonitorClientService monitorClientService;

    @RequestMapping(value = "/getClientList",method = RequestMethod.POST)
    @ResponseBody
    public List<MonitorClient> getClientList(){
        return monitorClientService.getAllClients();
    }

    @RequestMapping(value = "/addClient",method = RequestMethod.POST)
    @ResponseBody
    public int addClient(MonitorClient monitorClient){
        return monitorClientService.addClient(monitorClient);
    }

    @RequestMapping(value = "/getClient",method = RequestMethod.POST)
    @ResponseBody
    public MonitorClient getMonitorClientById(Integer id){
        return monitorClientService.getMonitorById(id);
    }

    @RequestMapping(value = "/updateClient",method = RequestMethod.POST)
    @ResponseBody
    public int updateClient(MonitorClient monitorClient){
        return monitorClientService.updateMonitor(monitorClient);
    }
}

httpPost请求过去之后，能够执行到Controller的getMonitorClientById()方法，但是无法获取的Id的数值，用jquery写的ajax的Post请求是可以的！
此外，测过该httpPost的java代码，请求别人的服务是正常的，能获取参数，也能正常的返回结果数据。希望高手指导

传的string类型的json给int类型的id 当然是没用的啦

。。。楼上正解。

加注解 public MonitorClient getMonitorClientById(@RequestBody Integer id){ } 我向来是用类接受的，没有直接用单变量试过，你试试看 springmvc 需要Jackson 2.5库，记得添加。

你把Integer类型改成String类型的试试，有可能是类型转换
