Json数据和对象互转

1、创建UserTest类

package com.cppdy;

public class UserTest {

    private String name;
    private String sex;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getSex() {
        return sex;
    }

    public void setSex(String sex) {
        this.sex = sex;
    }

    @Override
    public String toString() {
        return "User [name=" + name + ", sex=" + sex + "]";
    }

}

2、创建JsonTest1类测试互转

package com.cppdy;

import com.alibaba.fastjson.JSONObject;

public class JsonTest1 {

    public static void main(String[] args) {
        JSONObject ob = new JSONObject();
        ob.put("name", "吹泡泡的魚");
        ob.put("sex", "男");

        UserTest user = JSONObject.toJavaObject(ob, UserTest.class);
        System.out.println("JSON转Object:" + user.toString());

        UserTest u = new UserTest();
        u.setName("cppdy");
        u.setSex("nan");

        String jsonString = JSONObject.toJSONString(u);
        System.out.println("Object转JSON:" + jsonString);

    }

}
