使用fastjson 進行jsonObject轉實體類對象

       <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>fastjson</artifactId>
            <version>1.2.7</version>
        </dependency>

首先引入相關jar包，

假設有一個實體類User

public class User{
  private int id;
  private String name;    
}

然后通過fastJson進行類型轉換

public static void main(String[] args){
    String userString = "{"id":1,"name","lz"}";
    JSONObject userJson = JSONObject.parseObject(userString);
   User user = JSON.toJavaObject(userJson,User.class);
   
}
