sitemesh

JavaScript JSP XML CSS jQuery

1.加入包

sitemesh-2.3.jar

2.在web.xml中配置过滤器

<filter>
        <filter-name>sitemesh</filter-name>
        <filter-class>
            com.opensymphony.module.sitemesh.filter.PageFilter
        </filter-class>
    </filter>
    <filter-mapping>
        <filter-name>sitemesh</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

3.在web-info下建立文件decorators.xml，文件例如

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

<decorators defaultdir="/decorators">

<excludes>
  <pattern>/login.jsp</pattern>
  <pattern>/js/*</pattern>
  <pattern>/images/*</pattern>
  <pattern>/decorators/*</pattern>

ajax等异步请求要写在这里
</excludes>

<decorator name="admin" page="admin/admin.jsp">
  <pattern>/admin/welcome.action</pattern>
  <pattern>/admin/pubinfo/*</pattern>
</decorator>
<decorator name="index" page="index/index.jsp">
  <pattern>/index/classify/index*</pattern>
</decorator>
</decorators>

4.在web-info下建立文件sitemesh.xml，文件例如

由sitemesh.xml内容首行知道，decorators.xml是由sitemesh.xml关也就是说上面新建的 decorators.xml的位置和文件名是可以更改的，在更改之后，需要在sitemesh.xml更改其对应的路径。现在可以这样认为 sitemesh.xml只是为加载decorators.xml，只了decorators.xml可以变，其它内容都是固定的。

那sitemesh.xml又是由谁来加载的？很容易想到，sitemesh.xml可能像struts,spring等配置文件一样是在 web.xml中加载的。但是其实不是这样的。Sitemesh.xml文件的位置和文件名是固定的，也就是说sitemesh.xml的加载过程被 sitemesh jar包封装起来了。那web.xml中就不需要配置sitemesh相关内容了？也不是，sitemesh的原理是拦截请求和响应，在java web中有一个接口是专门弄这东西的。对，就是Filter(过滤器)。我们要在web.xml中加上sitemesh过滤器。

5.建立对应的模板main.jsp

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@ taglib uri="http://www.opensymphony.com/sitemesh/decorator"
    prefix="decorator"%>
    <%@ taglib uri="http://www.opensymphony.com/sitemesh/page" prefix="page"%>
    <%@include file="../frame/taglib.jsp"%>

<%
    String path = request.getContextPath();
    String basePath = request.getScheme() + "://"
            + request.getServerName() + ":" + request.getServerPort()
            + path + "/";

    %>
