sitemesh初步

發(fā)布時間：2023/12/20 编程问答 34 豆豆
生活随笔 收集整理的這篇文章主要介紹了 sitemesh初步 小編覺得挺不錯的,現(xiàn)在分享給大家,幫大家做個參考.

sitemesh小項目

1.工程目錄

2.需要的lib:sitemesh-2.4.2.jar
http://wiki.sitemesh.org/wiki/display/sitemesh/Download
3.配置
decorators.xml[sitemesh的配置文件]

<?xml version="1.0" encoding="ISO-8859-1"?><!-- 在defaultdir目錄查找decorator文件 --> <decorators defaultdir="/WEB-INF/decorator"><!-- Any urls that are excluded will never be decorated by Sitemesh --><excludes><pattern>/exclude.jsp</pattern><pattern>/exclude/*</pattern></excludes><!-- 利用basic.jsp修飾所有的頁面 --><decorator name="basic" page="basic.jsp"><pattern>/*</pattern></decorator><!-- 僅僅只使用main.jsp修飾頁面/02.jsp；深度優(yōu)先，匹配最精確的，利用它來修飾 --><decorator name="main" page="main.jsp"><pattern>/02.jsp</pattern></decorator><!-- panel裝飾器會直接在01.jsp引入 --><decorator name="panel" page="panel.jsp"></decorator> </decorators>

web.xml[web工程的配置文件]:

<?xml version="1.0" encoding="UTF-8"?> <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_3_0.xsd" id="WebApp_ID" version="3.0"><display-name>sitemesh01</display-name><welcome-file-list><welcome-file>index.html</welcome-file><welcome-file>index.htm</welcome-file><welcome-file>index.jsp</welcome-file><welcome-file>default.html</welcome-file><welcome-file>default.htm</welcome-file><welcome-file>default.jsp</welcome-file></welcome-file-list><!-- 添加sitemesh的Filter,應(yīng)該放置為第一個過濾器的位置，防止意外 --><filter><filter-name>sitemesh</filter-name><filter-class>com.opensymphony.sitemesh.webapp.SiteMeshFilter</filter-class></filter><filter-mapping><filter-name>sitemesh</filter-name><url-pattern>/*</url-pattern></filter-mapping></web-app>

4.sitemesh的裝飾器
decorator/basic.jsp:
