javaEE--web.xml拆分

在不使用框架的前提下，通过使用xml内联dtd定义实体来实现web.xml拆分。附件给出的web.xml和web-servlets.xml实现了从web.xml中分离出servlet配置，便于工程管理。

<? xml version = "1.0" encoding = "UTF-8" ?>
<! DOCTYPE web-app [
    <!ENTITY webServlet SYSTEM "web-servlets.xml">
]>
< web-app xmlns:xsi = "http://www.w3.org/2001/XMLSchema-instance" xmlns = "http://java.sun.com/xml/ns/javaee" xsi:schemaLocation = "http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id = "WebApp_ID" version = "2.5" >

  &webServlet;

  < welcome-file-list >
    < welcome-file >index.html</ welcome-file >
    < welcome-file >index.htm</ welcome-file >
    < welcome-file >index.jsp</ welcome-file >
  </ welcome-file-list >
</ web-app >

  

< servlet >
    < servlet-name >SimpleServlet</ servlet-name >
    < servlet-class >com.hongyuan.test.SimpleServlet</ servlet-class >
</ servlet >
< servlet-mapping >
    < servlet-name >SimpleServlet</ servlet-name >
