Java 字符串转json解析【alibaba.fastjson.JSONObject】

json串儿：

{
    "id":"",
    "name":"模板一",
    "state":"1",
    "mixers":[
        {
            "id":0,
            "layout":"10",
            "rooms":[
                {
                    "index":0,
                    "roomid":"63",
                    "name":"天津"
                },
                {
                    "index":1,
                    "roomid":"55",
                    "name":"北京"
                }
            ]
        }
    ],
    "isadmin":"1",
    "ispoll":"1",
    "mixercnt":"1",
    "confNo":"10000"
}

代码：

import com.alibaba.fastjson.JSONObject;
import com.alibaba.fastjson.JSON;


import java.util.List;
public class StrTest {

    public static void main(String[] args) {
        String jsonstr="{"id":"","name":"模板一","state":"1","mixers":[{"id":0,"layout":"10","rooms":[{"index":0,"roomid":"63","name":"天津"},{"index":1,"roomid":"55","name":"北京"}]}],"isadmin":"1","ispoll":"1","mixercnt":"1","confNo":"10000"}";

        System.out.println(jsonstr);
        JSONObject TemplateObject = (JSONObject) JSONObject.parse(jsonstr);


        System.out.println(TemplateObject.get("id"));
        System.out.println(TemplateObject.get("name"));
        System.out.println(TemplateObject.get("state"));
        System.out.println(TemplateObject.get("isadmin"));
        System.out.println(TemplateObject.get("ispoll"));
        System.out.println(TemplateObject.get("mixercnt"));
        System.out.println(TemplateObject.get("confNo"));
        System.out.println(TemplateObject.get("mixers"));


        List MixerLayoutRoomList = JSON.parseArray(TemplateObject.get("mixers").toString(), TemplateMixerArrVo.class);

        for (int i = 0; i < MixerLayoutRoomList.size(); i++) {
            System.out.println(MixerLayoutRoomList.get(i).getId());
            System.out.println(MixerLayoutRoomList.get(i).getLayout());
            System.out.println(MixerLayoutRoomList.get(i).getRooms());

            List list=MixerLayoutRoomList.get(i).getRooms();
            for (MixerLayoutRoom mixerLayoutRoom:list) {
                System.out.println(mixerLayoutRoom.getName());
                System.out.println(mixerLayoutRoom.getRoomid());
            }
        }
    }
}

TemplateMixerArrVo类，3个属性解析使用

{
 "index":0,
 "roomid":"63",
 "name":"天津"
 }
