dom4j写xml文件测试：

package com.yanek.demo.xml.test;

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

import org.dom4j.Document;
import org.dom4j.DocumentHelper;
import org.dom4j.Element;
import org.dom4j.io.XMLWriter;

public class DOM4j {

public static void main(String[] args) {
// dom4j解析xml测试

// 1. dom4j写xml

  /*
   * <?xml version="1.0" encoding="UTF-8"?> <actions> <action path="/test"
   * class="com.mystruts.demo.LoginAction"> <forward name="success"
   * url="hello.jsp"/> <forward name="fail" url="fail.jsp"/> </action>
   * <action path="/user" class="com.mystruts.demo.UserAction"> <forward
   * name="success" url="list.jsp"/> <forward name="fail" url="fail.jsp"/>
   * </action> </actions>
   */
  Document document = DocumentHelper.createDocument();
  Element actionsElement = document.addElement("actions");

  Element actionElement1 = actionsElement.addElement("action");
  actionElement1.addAttribute("path", "/test");
  actionElement1.addAttribute("class", "com.mystruts.demo.LoginAction");

  Element forwardElement1 = actionElement1.addElement("forward");
  forwardElement1.addAttribute("name", "success");
  forwardElement1.addAttribute("url", "hello.jsp");

  Element forwardElement2 = actionElement1.addElement("forward");
  forwardElement2.addAttribute("name", "fail");
  forwardElement2.addAttribute("url", "fail.jsp");

  Element actionElement2 = actionsElement.addElement("action");
  actionElement2.addAttribute("path", "/user");
  actionElement2.addAttribute("class", "com.mystruts.demo.UserAction");

  Element forwardElement21 = actionElement2.addElement("forward");
  forwardElement21.addAttribute("name", "success");
  forwardElement21.addAttribute("url", "list.jsp");

  Element forwardElement22 = actionElement2.addElement("forward");
  forwardElement22.addAttribute("name", "fail");
  forwardElement22.addAttribute("url", "fail.jsp");

  try {
   /** 将document中的内容写入文件中 */
   XMLWriter writer = new XMLWriter(new FileWriter(new File(
     "d://mystruts.xml")));
   writer.write(document);
   writer.close();
   /** 执行成功,需返回1 */

  } catch (Exception ex) {
   ex.printStackTrace();
  }

System.out.println(document.asXML());

}

生成xml:

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