Java中如何将bean转换为XML持久性？

package org.nhooo.example.bean;

import java.beans.XMLEncoder;
import java.io.BufferedOutputStream;
import java.io.FileOutputStream;
import java.io.FileNotFoundException;

public class BeanToXML {
    private Long id;
    private String itemName;
    private String itemColour;
    private Integer itemQuantities;

    public static void main(String[] args) {
        BeanToXML bean = new BeanToXML();
        bean.setId(new Long(1));
        bean.setItemName("T-Shirt");
        bean.setItemColour("Dark Red");
        bean.setItemQuantities(new Integer(100));

        try {
            XMLEncoder encoder = new XMLEncoder(new BufferedOutputStream(
                    new FileOutputStream("Bean.xml")));

            //将指定对象的XML表示形式写入输出。
            encoder.writeObject(bean);
            encoder.close();
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        }
    }

    public Long getId() {
        return id;
    }

    public void setId(Long id) {
        this.id = id;
    }

    public String getItemName() {
        return itemName;
    }

    public void setItemName(String itemName) {
        this.itemName = itemName;
    }

    public String getItemColour() {
        return itemColour;
    }

    public void setItemColour(String itemColour) {
        this.itemColour = itemColour;
    }

    public Integer getItemQuantities() {
        return itemQuantities;
    }

    public void setItemQuantities(Integer itemQuantities) {
        this.itemQuantities = itemQuantities;
    }
}

XML持久性将类似于：

<?xml version="1.0" encoding="UTF-8"?> 
<java version="1.6.0_02"> 
 <object> 
  <void property="id"> 
   <long>1</long> 
  </void> 
  <void property="itemColour"> 
   <string>Dark Red</string> 
  </void> 
  <void property="itemName"> 
   <string>T-Shirt</string> 
  </void> 
  <void property="itemQuantities"> 
   <int>100</int> 
  </void> 
 </object> 
</java>
