如何使用java进行json数据解析？

使用org.json

import org.json.*;JSonObject obj = new JSonObject(" .... ");String pageName = obj.getJSonObject("pageInfo").getString("pageName");JSonArray arr = obj.getJSonArray("posts");for (int i = 0; i < arr.length(); i++){    String post_id = arr.getJSonObject(i).getString("post_id");    ......}

使用GSON

//from object to JSON Gson gson = new Gson();gson.toJson(yourObject);// from JSON to object yourObject o = gson.fromJson(JSONString,yourObject.class);
