谷歌对于JSON解析提供了一个开源框架称为GSON,相比于Java的Json要简单的多
解析
import com.google.gson.Gson;
import com.qf.demo.Person;
/**
* 谷歌的gson
* @author Administrator
*
*/
public class Test {
public static void main(String[] args) {
String string = "{name:'zhangsan',age:20}";
/**
* 1 创建工具对象
*/
Gson gson = new Gson();
// 第一个参数是要解析的json字符串
Person person = gson.fromJson(string, Person.class);
System.out.println(person);
}
}
反向操作
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);
}
}
