分类 : 编程语言 | 发布时间 : 2018-04-21 09:06:21 | 浏览 : 0

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>
