首先引入相关jar包，
假设有一个实体类User
public class User{ ?private int id; ?private String name; ???}然后通过fastJson进行类型转换
public static void main(String[] args){ ???String userString = "{"id":1,"name","lz"}"; ???JSONObject userJson = JSONObject.parseObject(userString); ??User user = JSON.toJavaObject(userJson,User.class); ??}使用fastjson 进行jsonObject转实体类对象
