SpringBoot 接口开发（httpclient客户端）

服务端

@RestController@RequestMapping("/landary")public class landaryController {    @RequestMapping("adduser")    public JSONObject addUser(@RequestBody JSONObject userEntity)    {        System.out.println(JSONObject.toJSONString(userEntity));        JSONObject json=new JSONObject();        json.fluentPut("code","500").fluentPut("result",userEntity);        return json;    }    @RequestMapping("showuser")    public Object showUser()    {        return JSON.toJSONString("hhh");    }}

客户端post请求
