SiteMesh在项目中的配置

SiteMesh在项目中的配置

首先在web.xml里面增加siteMesh的配置：

<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>*.do</url-pattern>

</filter-mapping>

<filter-mapping>

 <filter-name>sitemesh</filter-name>

 <url-pattern>*.jsp</url-pattern>

</filter-mapping>

凡是提交的.do和.jsp的请求，都要经过siteMesh的处理，哈哈，当然html的就不用处理啦

另外在WEB-INF下面还有一个配置sitemesh.xml：

<sitemesh>

 <property name="decorators-file" value="/WEB-INF/decorators.xml" />

 <excludes file="${decorators-file}" />

 <page-parsers>

  <parser content-type="text/html"

   class="com.opensymphony.module.sitemesh.parser.HTMLPageParser" />

 </page-parsers>

 <decorator-mappers>

  <mapper

   class="com.opensymphony.module.sitemesh.mapper.PageDecoratorMapper">

   <param name="property.1" value="meta.decorator" />

   <param name="property.2" value="decorator" />

  </mapper>

  <mapper

   class="com.opensymphony.module.sitemesh.mapper.FrameSetDecoratorMapper">

  </mapper>

  <mapper

   class="com.opensymphony.module.sitemesh.mapper.AgentDecoratorMapper">

   <param name="match.MSIE" value="ie" />

   <param name="match.Mozilla [" value="ns" />

   <param name="match.Opera" value="opera" />

   <param name="match.Lynx" value="lynx" />

  </mapper>

  <mapper

   class="com.opensymphony.module.sitemesh.mapper.PrintableDecoratorMapper">

   <param name="decorator" value="printable" />

   <param name="parameter.name" value="printable" />

   <param name="parameter.value" value="true" />

  </mapper>

  <mapper

   class="com.opensymphony.module.sitemesh.mapper.RobotDecoratorMapper">

   <param name="decorator" value="robot" />

  </mapper>

  <mapper

   class="com.opensymphony.module.sitemesh.mapper.ParameterDecoratorMapper">

   <param name="decorator.parameter" value="decorator" />

   <param name="parameter.name" value="confirm" />

   <param name="parameter.value" value="true" />

  </mapper>

  <mapper

   class="com.opensymphony.module.sitemesh.mapper.FileDecoratorMapper">

  </mapper>

  <mapper

   class="com.opensymphony.module.sitemesh.mapper.ConfigDecoratorMapper">

   <param name="config" value="${decorators-file}" />

  </mapper>

 </decorator-mappers>

</sitemesh>

其实这个配置倒是一般是默认的。嘿嘿。不过我当时也研究了一下。不过主要的还是这个文件是在SITEMESH的JAR包中自动装载进来的，它决定了另外一个配置文件的位置和名字，就是decorators.xml：

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

<decorators defaultdir="/decorators">

 <decorator name="default" page="default.jsp" />

 <decorator name="defaulths" page="default_hs.jsp"/>

 <decorator name="main" page="main.jsp" />

 <decorator name="mainhs" page="main_hs.jsp"/>

</decorators>

这里配置了4个渲染的模板，同时也给这四个模板定义了名字。看看模板的内容，比如这个main.jsp:

<%@ include file="/common/taglibs.jsp"%>

<html>

 <head>

  <title>

   <decorator:title default="DV110.com" />

  </title>

  <%@ include file="/common/meta.jsp"%>

  <decorator:head />

 </head>

 <body id="homepage">

  <div id="header">

   <jsp:include page="/common/header.jsp" />

  </div>

  <div align="center" style="height:500px;">

   <table border="0" cellpadding="0" cellspacing="0" width="779" align="center">

    <tr>

     <td valign="top" >

      <%@ include file="/common/messages.jsp"%>

      <h1 align="center">

       <decorator:getProperty property="page.heading" />

      </h1>

      <decorator:body />

     </td>

    </tr>

   </table>

  </div>

  <div id="footer">

   <jsp:include page="/common/footer.jsp" />

  </div>

 </body>

</html>

以上是系统知道要用SiteMesh来处理后，要使用的模板。

以下是系统的页面，比如设备更新页面，会在页面中有个<meta name="decorator" content="default${dName}">

其中content=""这里面的名字就是我们配置的模板的名字。

<%@ page language="java" errorPage="/error.jsp" pageEncoding="UTF-8"

 contentType="text/html;charset=UTF-8"%>

<%@ include file="/common/taglibs.jsp"%>

<html>

 <head>

  <title>设备信息更新</title>

  <meta name="decorator" content="default${dName}">

 </head>

 <body>

  <html:form action="deviceVIS.do?method=updateDevice" method="post">

   <html:hidden property="id" />

   <table width="516" border="0" align="center">

    <tr>

     <td width="84">

      设备名称

     </td>

     <td width="288">

      <html:text property="name" />

     </td>

     <td width="122">

       

     </td>

    </tr>

    <tr>

     <td>

      安装地址

     </td>

     <td>

      <html:text property="installLocation" />

     </td>

     <td>

       

     </td>

    </tr>

    <td>

      

    </td>

    <td>

     <input type="submit" name="Submit" value="保存" />

     <input type="reset" name="cancel" value="重置" />

    </td>

    <td>

      

    </td>

    </tr>

   </table>

  </html:form>

 </body>

</html>
