怎么解析这样的 以前没有接触过 我看网上的看的不是很理解
怎么把解析出来的数据 存到实体类中(更具上面key)

[hp961218]

是页面里面解析还是java代码里面解析json数据, jsp页面里面可以使用js脚本里的eval(json)转成集合类型,代码里面可以使用fastJson Gson等

昨天看了一下教程已完成 留下一个例子 给需要的人吧

	public static void main(String[] args) {
		String[] array = {"album","mv","singer","song"};
		for (int i = 0; i < array.length; i++) {
			System.out.println(array[i]+":-------------------------------------------");
			List<Item> albumItemlist = getDataItemlist(array[i]);
			for (Item item : albumItemlist) {
				System.out.println("歌手:" + item.getSinger() +  "   专辑名称:"  + item.getName() );
			}
		}
		
	}
	
	
	public static List<Item> getDataItemlist(String name){
		//把json存储到一个jsonObject类型中
		JSONObject jsonObject = new JSONObject(Json_info());
		jsonObject =  jsonObject.getJSONObject("data");
		//取第一个对象album
		JSONObject album = jsonObject.getJSONObject(name);
		JSON_Respones albumJson = new JSON_Respones();
		albumJson.setCount(album.getInt("count"));
		//获取itemlist 的数组
		JSONArray jsonArray = album.getJSONArray("itemlist");
		//存储album下itemlist数据集合
		List<Item> albumItemlist = new ArrayList<Item>();
		for (int i = 0; i < jsonArray.length(); i++) {
			Item it = new Item();
			JSONObject albumItemInfo = (JSONObject)jsonArray.get(i);
			//设置albumItem属性值
			it.setSinger(albumItemInfo.getString("singer"));
			it.setDocid(albumItemInfo.getString("docid"));
			it.setName(albumItemInfo.getString("name"));
			it.setMid(albumItemInfo.getString("mid"));
			it.setId(albumItemInfo.getString("id"));
			if(name == "album"){
				it.setPic(albumItemInfo.getString("pic"));
			}
			if(name == "mv"){
				it.setVid(albumItemInfo.getString("vid"));
			}
			albumItemlist.add(it);
		}
		return albumItemlist;
	}

根据key分析 有几层 一层一层解析就行了 给你网址在线生成了一份研究研究 https://tool.lu/json/

[qq_16694907]

JSONObject 可以直接转 Map

[oyljerry]

直接用Gson

[zoujiawei6]

在java层，解析json有json.jar和jackson.jar两个工具包，网上找的到。 jackson.jar下载地址：http://download.csdn.net/download/c15959140478/7716941 示例：http://blog.csdn.net/zoujiawei6/article/details/77866954 要理解原理的话可以自己写，就是通过反射把json与类对应。 需要jsckson解析示例的话再问我。
