2             <groupId>com.alibaba</groupId>
3             <artifactId>fastjson</artifactId>
4             <version>1.2.7</version>

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);
   
}
