@Data

@XStreamAlias("Struct")

public class User {

@XStreamAlias("USER_NAME")

private String name;

@XStreamAlias("USER_SEX")

private String sex;

@XStreamAlias("USER_AGE")

private int age;

 

}

 

UserPad类

 

package com.bean;

 

import java.util.List;

 

import com.thoughtworks.xstream.annotations.XStreamAlias;
