Hutool将Java对象转换为JSON字符串呢?

JSON将对象转换为JSON字符串的实现思路

1.引入hutool-json框架
2.使用JSONUtil.toJsonStr()方法即可将对象转换为JSON字符串

    <dependency>
    <groupId>cn.hutool</groupId>
    <artifactId>hutool-json</artifactId>
    <version>5.5.14</version>
</dependency>

import cn.hutool.json.JSONUtil;
 
public class Main {
    public static void main(String[] args) {
        // 创建一个Java对象
        User user = new User("Java265.com", 25, "admin@java265.com");
 
        // 将Java对象转换为JSON字符串
        String jsonStr = JSONUtil.toJsonStr(user);
 
        // 打印JSON字符串
        System.out.println(jsonStr);
    }
}
 
class User {
    private String name;
    private int age;
    private String email;
 
    public User(String name, int age, String email) {
        this.name = name;
        this.age = age;
        this.email = email;
    }
 
    // 省略getter和setter方法
}
