dom4j 生成XML
需要導包

           <dependency>
                 <groupId>dom4j</groupId>
                 <artifactId>dom4j</artifactId>
                 <version>1.6.1</version>
           </dependency>

例子：

package test;

import org.dom4j.Document;
import org.dom
 
4j.DocumentHelper;
import org.dom4j.Element;

public class XMLdemo {

      public static void main(String[] args) {

           Document document=DocumentHelper.createDocument();
           Element rootElm = document.addElement("XML");
           rootElm.addElement("ToUserName").addCDATA("openid");
 

           rootElm.addElement("FromUserName").addCDATA("xilaiID");
            rootElm.addElement("CreateTime").addCDATA("1492737230254");
           rootElm.addElement("MsgType").addCDATA("news");
           rootElm.addElement("ArticleCount").addCDATA("1");

           Element contentElm=rootElm.addElement
 
("Articles");
           contentElm.addElement("Title").addCDATA("歡迎關注");
           contentElm.addElement("Description").addCDATA("點點點");
            contentElm.addElement("PicUrl").addCDATA("http://60.205.138.165:8080/wechatServlet/forward/toOrderQuick");
            contentElm.addElement("Url").addCDATA("http://60.205.138.165:8080/wechatServlet/forward/toOrderQuick");

      String xmlaa=document.getRootElement().asXML();  //去掉頭資訊檔案
      System.out.println(xmlaa);
      }
}

輸出：

<XML>
     <ToUserName><![CDATA[openid]]></ToUserName>
     <FromUserName><![CDATA[xilaiID]]></FromUserName>
     <CreateTime><![CDATA[1492737230254]]></CreateTime>
     <MsgType><![CDATA[news]]></MsgType>
     <ArticleCount><![CDATA[1]]></ArticleCount>
     <Articles>
          <Title><![CDATA[歡迎關注]]></Title>
          <Description><![CDATA[點點點]]></Description>
          <PicUrl><![CDATA[http://60.205.138.165:8080/wechatServlet/forward/toOrderQuick]]></PicUrl>
          <Url><![CDATA[http://60.205.138.165:8080/wechatServlet/forward/toOrderQuick]]></Url>
     </Articles>
</XML>
