Gson的简单使用

package com.JavaSE.day10;

import java.util.ArrayList;
import java.util.List;

import net.sf.json.JSON;

import com.JavaSE.day03.Person;
import com.google.gson.Gson;
import com.google.gson.JsonElement;
import com.google.gson.JsonParser;
import com.google.gson.reflect.TypeToken;

public class JsonTest {

public static void main(String[] args) {

Gson gson = new Gson();

Person p = new Person("freshbin", 22);
System.out.println(gson.toJson(p));

List<Person> listPerson = new ArrayList<Person>();

Person p1 = new Person("tyb", 22);
Person p2 = new Person("freshbin", 23);

listPerson.add(p1);
listPerson.add(p2);

System.out.println("-------------------");

String lp = gson.toJson(listPerson);
System.out.println(lp);

System.out.println("--------------------");

//将字符串解析成对象
Person p4 = gson.fromJson(gson.toJson(p), Person.class);

System.out.println(p4.getName());
System.out.println(p4.getCardId());

System.out.println("------------------------");

//解析集合中的对象，使用TypeToken
List<Person> alist = gson.fromJson(lp, new TypeToken<List<Person>>(){}.getType());

for(Person p0 : alist) {
System.out.println(p0.getName());
System.out.println(p0.getCardId());
}

}
