How to assign the json data type directly to the corresponding object

Today, I will talk to you about how the json data type is directly assigned to the corresponding object, which may not be well understood by many people. In order to make you understand better, the editor has summarized the following content for you. I hope you can get something according to this article.

First, introduce fastjson.jar package into maven project

Com.alibaba fastjson 1.1.41

Second, create solid objects

Package json;public class User {public String name; public String age; public String sex; public String getName () {return name;} public void setName (String name) {this.name = name;} public String getAge () {return age } public void setAge (String age) {this.age = age;} public String getSex () {return sex;} public void setSex (String sex) {this.sex = sex;}}

Third, create test classes

Package json;import com.alibaba.fastjson.JSON;public class JsonTest {public static void main (String [] args) {/ / TODO Auto-generated method stub String str= "{\" name\ ":\" Sun WuKong\ ",\" age\ ":\" 500\ ",\" sex\ ":\" Fire Eye Crystal male Monkey} "; User user=JSON.parseObject (str, User.class) System.out.println (user.getName ());}} after reading the above, do you have any further understanding of how the json data type is assigned directly to the corresponding object?
