SpringMVC 接收页面Post提交的json字符串并解析

来源：互联网发布：matlab7,1如何进入编程编辑：程序博客网时间：2024/05/23 02:07

json 使用的是ali的fastjson;

页面提交的是json字符串，后台使用@RequestBody String param接收数据，通过json解析param;

页面：

<%@ page language="java" contentType="text/html; charset=utf-8"    pageEncoding="utf-8"%><!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><html><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8"><title>Insert title here</title><script type="text/javascript" src="jquery.min.js"></script><script type="text/javascript">function testSpringParam(){ var name=$("#name").val();var email=$("#email").val();$.ajax({    type: 'POST',    url: 'paramurl/paramTest.do' ,       dataType: 'text',    contentType:'application/json;charset=UTF-8',    data:JSON.stringify([{'name':name,'email':email}]),  //提交json字符串数组，如果提交json字符串去掉[] success:function(data){alert(data);},error:function(textStatus, errorThrown){console.log(textStatus);alert(textStatus);}});}</script></head><body><form action="" id="f1" name="f1"><input name="name" id="name"  type="text"  value="zhangsan1"><br><input name="email" id="email" type="text" value="zhangsan@163.com"><br><br><a href="#" onclick="testSpringParam();">测试</a></form></body></html>

后台代码：

package com.pb.web.controller;import java.util.List;import java.util.Map;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestBody;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RequestMethod;import org.springframework.web.bind.annotation.ResponseBody;import com.alibaba.fastjson.JSONArray;import com.alibaba.fastjson.JSONObject;@Controller@RequestMapping("/paramurl")public class ParamController {@RequestMapping(value="/paramTest.do",method=RequestMethod.POST)@ResponseBodypublic String paramTest(@RequestBody String param){System.out.println(param);JSONObject jo=new JSONObject();//如果页面传的是json字符串，用下列方式解析//Map<String, Object> m=(Map<String, Object> )jo.parse(param); //string转map//System.out.println(m);////JSONObject parseObject = jo.parseObject(param); //string转json//System.out.println(parseObject);//如果页面传的是json数组字符串，用下列方式解析List<Map> parseArray = jo.parseArray(param, Map.class);System.out.println(parseArray); //string转listJSONArray parseArray2 = jo.parseArray(param);System.out.println(parseArray2);return "ok";}}
