Json数据转换成对象

1、测试类

package test;

import net.sf.json.JSONObject;

public class Test {

	
	public static void main(String[] args) {
		// TODO Auto-generated method stub	
		String s="{'name':'张三','age':20}";
		JSONObject obj=JSONObject.fromObject(s);
		User user=(User) JSONObject.toBean(obj,User.class);
		System.out.println(user.getName());
		
	}

}


2、User类

package test;

public class User {

	private String name;
	private int age;
	
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public int getAge() {
		return age;
	}
	public void setAge(int age) {
		this.age = age;
	}
	
}
