使用谷歌的gson生成数据

1 . 比原生的json解析生成数据简单

package com.qf.demo4;import com.google.gson.Gson;import com.qf.demo.Person;public class Test {    public static void main(String[] args) {        Gson gson = new Gson();        Person person = new Person("zhangsan", 20);        String string = gson.toJson(person);        System.out.println(string);    }}

2 .

package com.qf.demo4;import com.google.gson.Gson;import com.qf.demo3.Dept;import com.qf.demo3.Person;public class Test2 {    public static void main(String[] args) {        Person person = new Person("zhangsan", 10, new Dept(2, "hehe"));        Gson gson = new Gson();        String json = gson.toJson(person);        System.out.println(json);    }}
