本文实例讲述了java使用Jdom实现xml文件写入操作的方法。分享给大家供大家参考，具体如下：

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>
