此工具类，用于返回json对象=========================================================================================/** * 2017年10月20日下午3:29:05 */package com.jjmc.dcl.util;import java.io.Serializable;/** * * @author huangtao * 2017年10月20日下午3:29:05 * dclTask * @parameter * TODO * */public class RespsonData implements Serializable  {private static final long serialVersionUID = -8516663678560534209L;private String res;// 操作状态private String msg;// 返回信息    private Object data;    // 返回数据public RespsonData(String res) {this.res = res;}public RespsonData(String res, String msg) {this.res = res;this.msg = msg;}public void result(String res, String msg) {this.res = res;this.msg = msg;}public String getRes() {return res;}public void setRes(String res) {this.res = res;}public String getMsg() {return msg;}public void setMsg(String msg) {this.msg = msg;}public Object getData() {        return data;    }    public void setData(Object data) {        this.data = data;    }@Override    public String toString() {        return "RespsonData{" +                "res='" + res + '\'' +                ", msg='" + msg + '\'' +                ", data=" + data +                '}';    }    }===============================================================================引用方法在需要返回结果的接口类中 private RespsonData rd = new RespsonData("success");// 通用返回JSON对象接口使用@ResponseBody注解，会自动把结果转换成json格式此为测试接口，成功返回的是success，失败返回的是error的json格式private RespsonData rd = new RespsonData("success");@RequestMapping(method={RequestMethod.POST}, value="/XXXXXX")@ResponseBodyprotected Object getXXXXXXX(HttpServletRequest request, HttpServletResponse response) throws Exception{try {} catch (Exception e) {rd.setRes("error");throw e;}return rd;}
