1.所需要的jar包

2.编写实体类

package com.yun.bean;public class Product {private Integer id;private String name;private int price;public Integer getId() {return id;}public void setId(Integer id) {this.id = id;}public String getName() {return name;}public void setName(String name) {this.name = name;}public int getPrice() {return price;}public void setPrice(int price) {this.price = price;}}

3.编写测试类

package com.yun.test;import java.util.ArrayList;import java.util.HashMap;import java.util.List;import java.util.Map;import javax.xml.ws.Endpoint;import net.sf.json.JSONArray;import net.sf.json.JSONObject;import com.yun.bean.Product;import com.yun.service.User.impl.UserServiceImpl;public class Test {/** * @param args */public static void main(String[] args) {// TODO Auto-generated method stub//对象转化成json字符串Product p=new Product();p.setId(1);p.setName("刘云生1");p.setPrice(100);Product p1=new Product();p1.setId(2);p1.setName("刘云生2");p1.setPrice(100);List<Product> list=new ArrayList<Product>();list.add(0, p);list.add(1, p1);JSONArray json=JSONArray.fromObject(list);String s=json.toString();System.out.println(s);        //json数组转对象String json2 = "{name=\"刘云生\",bool:true,int:1,double:2.2,func:function(a){ return a; },array:[1,2]}";JSONObject jo=JSONObject.fromObject(json2);Object o=JSONObject.toBean(jo);String name=(String) jo.get("name");System.out.println(jo);System.out.println(name);}}
