Java中如何将XML持久性转换为Java Bean？
在前面的示例中，您可以看到如何将bean转换为XML持久性。现在我们做相反的事情，将XML转换回bean。对于BeanToXML此示例中使用的类，请参阅如何将bean转换为XML持久性？例。
package org.nhooo.example.bean;
import java.beans.XMLDecoder;
import java.io.BufferedInputStream;
public class XmlToBean {
public static void main(String[] args) {
XMLDecoder decoder = new XMLDecoder(new BufferedInputStream(
XmlToBean.class.getResourceAsStream("Bean.xml")));
//从基础输入流中读取下一个对象。
BeanToXML bean = (BeanToXML) decoder.readObject();
decoder.close();
System.out.println("ID = " + bean.getId());
System.out.println("Item Name = " + bean.getItemName());
System.out.println("Item Colour = " + bean.getItemColour());
System.out.println("Item Quantities = " + bean.getItemQuantities());
}
}这是我们的Bean.xml持久性文件：
<?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>
结果是：
ID = 1Item Name = T-ShirtItem Colour = Dark RedItem Quantities = 100
