Rhythmk 一步一步学 JAVA(3): java JSON 数据序列化 以及反序列化

package App1.Rhythmk.com;

import java.awt.List;

import com.google.gson.Gson;

public class JSON序列化 {

    /**
     * @param args
     */
    public static void main(String[] args) {
        // TODO Auto-generated method stub
        Serialize();
        Deserialize();

        /*
         * 输出: ["rhythmk1","rhythmk2","rhythmk3","rhythmk4"] 1
         * ["list1","list2","list3"] {"age":12,"name":"王坤"} List length =3
         */
    }

    /*
     * 序列化
     */
    public static void Serialize() {
        String[] strArray = new String[4];
        strArray[0] = "rhythmk1";
        strArray[1] = "rhythmk2";
        strArray[2] = "rhythmk3";
        strArray[3] = "rhythmk4";

        Gson gson = new Gson();
        System.out.println(gson.toJson(strArray));

        System.out.println(gson.toJson(1));

        List list = new List();
        list.add("list1");
        list.add("list2");
        list.add("list3");
        // List 序列化 需要 getItems
        System.out.println(gson.toJson(list.getItems()));

        User user = new User();
        user.setAge(12);
        user.setName("王坤");
        System.out.println(gson.toJson(user));

    }

    /*
     * 反序列化
     */
    public static void Deserialize() {
        String str = "[\"list1\",\"list2\",\"list3\"]";
        String[] arry = new Gson().fromJson(str, String[].class);
        System.out.print("List length  =" + arry.length);
    }

}
