user.java

import java.io.Serializable;    
     public class User implements Serializable{

BaseBean.java

          userList.add(user);       
       }

xstream代码

public class XStreamTest {    
         public static void main(String[] args) {    
             //javabean 转 xml     
             List<User> users = new ArrayList<User>();

             BaseBean base = new BaseBean();    
             base.setUserList(users);    
             XStream xs = new XStream();

             xs.alias("user", User.class);    
             xs.aliasField("list", BaseBean.class, "userList");    
             String xml=xs.toXML(base);    
             System.out.println("javabean转成xml为:\n"+xml);    
                 
             //xml转javabean     
             XStream xs1 = new XStream(new DomDriver());    
             xs1.alias("root", BaseBean.class);

             users=base.getUserList();    
             System.out.println("xml转成javabean为:");    
             for(User u:users){    
                 System.out.println("id="+u.getId()+",name="+u.getName()+",age="+u.getAge());
