1.导入对SiteMesh.jar的依赖
<dependency>
<groupId>org.sitemesh</groupId>
<artifactId>sitemesh</artifactId>
<version>3.0.0</version>
</dependency>
2.web.xml中配置过滤器
<!-- SiteMesh -->
<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>
3.WEB-INF中配置文件decorators.xml
<!-- /WEB-INF/content/theme表示存放模板(主题)的文件夹 -->
<?xml version="1.0" encoding="UTF-8"?>
<decorators defaultdir="/WEB-INF/content/theme">
<!-- name随意起 page主题网页 -->
<decorator name="simple-theme" page="layout.jsp">
<!-- 指的是所有网页都进行装饰 -->
<pattern>/*</pattern>
</decorator>
<excludes>
<!-- 表示静态资源不受影响,img表示静态资源文件夹 -->
<pattern>/img/*</pattern>
</excludes>
<excludes>
<!-- 表示除了这个网页 -->
<pattern>/admin/home.action</pattern>
</excludes> </decorators>
4.模板jsp的设置,需要导入标签
<%@ page language="java" pageEncoding="UTF-8"%>
<%@ taglib prefix="sitemesh-decorator" uri="http://www.opensymphony.com/sitemesh/decorator"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title><sitemesh-decorator:title/></title>
<!-- 头部也要导入,比如css之类的 -->
<sitemesh-decorator:head/>
</head>
<body>
<h1>head head</h1>
<!-- 导入body的部分 -->
<sitemesh-decorator:body/>
<h1>这是底部</h1>
</body>
</html>
