java，jsp读取xml文件，并显示读取内容

本人是在jsp中写java文件，读取xml文件中的内容，并在页面显示。tangyj

1.下载jar包

2.写xml文件

3.在jsp中写java读取xml内容

<%@pageimport="org.jdom2.Document"%>

<%@ page import = "org.jdom2.input.SAXBuilder" %>

<%@ page import = "org.jdom2.output.Format" %>

<%@ page import = "org.jdom2.output.XMLOutputter" %>

<%@ page import = "org.jdom2.Element" %>

<%@ page import = "java.io.*" %>

<%@ page import = "java.util.*" %>

加入jar包

jdom.jar

<%

String path=pageContext.getServletContext().getRealPath( "version.xml" );

System.out.println(path+ "----------------7----==---" );

SAXBuilder sb = new SAXBuilder(); // 新建立构造器

Document doc1 = sb.build( new FileInputStream(path));

Element root1=doc1.getRootElement();

String smtpusername= "" ; //用户名

String smtppwd= "" ; //密码

String smtpserver= "" ; //邮件服务器域名

Listlist1=root1.getChildren( "person" );

for ( int ii=0;ii<list1.size();ii++){

Element element=(Element)list1.get(ii);

smtpusername=element.getChildText( "name" );

smtppwd=element.getChildText( "ver" );

smtpserver=element.getChildText( "publish" );

System.out.println(smtpusername+ "--" +smtppwd+ "--" +smtpserver);

}

%>

将你读取的内容，在jsp页面用<%=smtpserver>显示即可

//这个是建立的xml文件

version.xml在我的根目录下，就是项目启动部署的目录

<? xml version = "1.0" encoding = "UTF-8" ?>

< version >

< person id = "01" >

< name >lhl </ name >

< ver > v1.0 </ ver >

< publish > 2013-08-22 </ publish >

< company > zkr </ company >

</ person >

< person id = "01" >

< name >tangyj </ name >

< ver > v1.1 </ ver >

< publish > 2013-08-25 </ publish >

< company >zkr </ company >

</ person >

</ version >
