使用 XML 工具： spring-oxm

spring 为 jaxb, jibx, xstream 这些封装提供了统一的接口。

}

实体类

package org.example;

import lombok.Data;

import javax.xml.bind.annotation.XmlRootElement;

@Data
@XmlRootElement
public class Person {
    private String id;
    private String name;
    private Integer age;
}

输出

<org.example.Person><id>111</id><name>222</name><age>333</age></org.example.Person>
