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>
