本文展示了如何使用XStream将JavaBean对象转换为XML，并实现从XML反序列化回JavaBean的过程。

直接贴代码:

User.java

package com.huilan.wcm.util.XStream;

import java.io.Serializable;
public class User implements Serializable{
	
	private String id;
	private String name;
	private String age;
	public User(){
		
	}
	public User(String id,String name,String age){
		this.id=id;
		this.name=name;
		this.age=age;
	}
	public String getId() {
		return id;
	}
	public void setId(String id) {
		this.id = id;
	}
	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;
	}
   
    
}

BaseBean.java

package com.huilan.wcm.util.XStream;

import java.util.ArrayList;
import java.util.List;

public class BaseBean{
	private List<User> userList;
    public BaseBean(){
    	userList = new ArrayList<User>();
    }
	public List<User> getUserList() {
		return userList;
	}

	public void setUserList(List<User> userList) {
		this.userList = userList;
	}
	 public void addUser(User user) {   
		 userList.add(user);   
	  }
}

测试类XStreamTest.java

package com.huilan.wcm.util.XStream;

import java.util.ArrayList;
import java.util.List;

import com.huilan.wcm.util.Betwixt.BaseBean;
import com.huilan.wcm.util.Betwixt.User;
import com.thoughtworks.xstream.XStream;
import com.thoughtworks.xstream.io.xml.DomDriver;

public class XStreamTest {
	public static void main(String[] args) {
		//javabean 转 xml
		List<User> users = new ArrayList<User>();
		users.add(new User("123", "艾丝凡", "23"));
		users.add(new User("456", "呃呃呃", "24"));
		BaseBean base = new BaseBean();
		base.setUserList(users);
		XStream xs = new XStream();
		xs.alias("root", BaseBean.class);
		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);
		xs1.alias("user", User.class);
		xs1.aliasField("list", BaseBean.class, "userList");
		base=(BaseBean)xs1.fromXML(xml);
		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());
		}
	}

}

输出结果:

javabean转成xml为:
<root>
<list>
<user>
<id>123</id>
<name>艾丝凡</name>
<age>23</age>
</user>
<user>
<id>456</id>
<name>呃呃呃</name>
<age>24</age>
</user>
</list>
</root>
xml转成javabean为:
id=123,name=艾丝凡,age=23
id=456,name=呃呃呃,age=24
