Jdom写xml文件实例

package com.yanek.demo.xml.test;

import java.io.File;
import java.io.FileWriter;

import org.jdom.Attribute;
import org.jdom.Document;
import org.jdom.Element;
import org.jdom.input.SAXBuilder;
import org.jdom.output.XMLOutputter;

public class JdomWriteXml {

/**
* @param args
*/
public static void main(String[] args) {

SAXBuilder sb = new SAXBuilder();

Element actions = new Element("actions");
Document document = new Document(actions);

Element action1 = new Element("action");
actions.addContent(action1);
Attribute path_atbt1 = new Attribute("path", "/test");
Attribute class_atbt1 = new Attribute("class",
"com.mystruts.demo.LoginAction");
action1.setAttribute(path_atbt1);
action1.setAttribute(class_atbt1);

Element action1_forward1 = new Element("forward");
action1.addContent(action1_forward1);
Attribute action1_forward1_name_atbt1 = new Attribute("name", "success");
Attribute action1_forward1_url_atbt1 = new Attribute("url", "test.jsp");
action1_forward1.setAttribute(action1_forward1_name_atbt1);
action1_forward1.setAttribute(action1_forward1_url_atbt1);

Element action1_forward2 = new Element("forward");
action1.addContent(action1_forward2);
Attribute action1_forward1_name_atbt2 = new Attribute("name", "failure");
Attribute action1_forward1_url_atbt2 = new Attribute("url",
"failure.jsp");
action1_forward2.setAttribute(action1_forward1_name_atbt2);
action1_forward2.setAttribute(action1_forward1_url_atbt2);

Element action2 = new Element("action");
actions.addContent(action2);
Attribute path_atbt2 = new Attribute("path", "/user");
Attribute class_atbt2 = new Attribute("class",
"com.mystruts.demo.UserAction");
action2.setAttribute(path_atbt2);
action2.setAttribute(class_atbt2);

Element action2_forward1 = new Element("forward");
action2.addContent(action2_forward1);
Attribute action2_forward1_name_atbt1 = new Attribute("name", "success");
Attribute action2_forward1_url_atbt1 = new Attribute("url", "test.jsp");
action2_forward1.setAttribute(action2_forward1_name_atbt1);
action2_forward1.setAttribute(action2_forward1_url_atbt1);

Element action2_forward2 = new Element("forward");
action2.addContent(action2_forward2);
Attribute action2_forward1_name_atbt2 = new Attribute("name", "failure");
Attribute action2_forward1_url_atbt2 = new Attribute("url",
"failure.jsp");
action2_forward2.setAttribute(action2_forward1_name_atbt2);
action2_forward2.setAttribute(action2_forward1_url_atbt2);

Attribute root_atbt1 = new Attribute("m", "001");
actions.setAttribute(root_atbt1);

try {
File f1 = new File("mystruts.xml");
// XMLOutputter xo=new XMLOutputter(" ",true,"GB2312");
XMLOutputter xo = new XMLOutputter();
FileWriter fw = new FileWriter(f1);
xo.output(document, fw);
fw.close();
} catch (Exception e) {
e.printStackTrace();
}
// System.out.println(document.toString());

}

生成xml文件：

<?xml version="1.0" encoding="UTF-8"?>
<actions m="001"><action path="/test" class="com.mystruts.demo.LoginAction"><forward name="success" url="test.jsp" /><forward name="failure" url="failure.jsp" /></action><action path="/user" class="com.mystruts.demo.UserAction"><forward name="success" url="test.jsp" /><forward name="failure" url="failure.jsp" /></action></actions>
