JSON object to convert Java object

Public static void main (String[] args)  {string studentjson= "{\" username\ ": \" Xiaoming\ ", \" age\ ": 20,\" desc\ ": \" good student \ "}"; string studentjson2= "{\" username\ ": \" xiaohong\ ", \" age\ ": 20,\" desc\ ": \" good student \ "}"; String[] json={studentjson,studentjson2};       //student st= ( Student)  json2bean (studentjson, student.class);        jsonarray  jsonarray=jsonarray.fromobject (JSON);//json objects hold a lot of student data        for ( Object obj:jsonarray) {       student st= (Student)  json2Bean ( ((Jsonobject)  obj). ToString (),  student.class);        System.out.println (St.getusername () + ":" +st.getdesc ());       }}    public static object json2bean (STRING JSON,CLASS CLA) {JSONObject  Jsonobject=jsonobject.fromobjeCT (JSON); Return jsonobject.tobean (JSONOBJECT, CLA);} 

Using the Json-lib framework, you can convert the foreground JSON object into a Java object, you need the following jar package, you can put the JSON data structure of multiple Java objects in the database, the use of Jsonarray into a JSON array, It then iterates through the array to get the Java object corresponding to each JSON data, and calls Jsonobject's Tobean method to get the object instance
