Struts Tiles 初实践

标签：struts tiles   页面模板引擎   

Struts Tiles 是一个页面模板引擎，属于视图层。定义页面布局，不指定里面的内容，当web页面运行时，才把特定的jsp内容插入到模板中显示。

该案例涉及到的file：web.xml,struts-default.xml,tiles-defs.xml,sidepanel.jsp, welcome.jsp

1.  Web.xml

  <!--Action Servlet Configuration -->

 <servlet>

   <servlet-name>action</servlet-name>

   <servlet-class>org.apache.struts.action.ActionServlet</servlet-class>

   <init-param>

     <param-name>config</param-name>

     <param-value>/WEB-INF/struts-default.xml</param-value>

   </init-param>

   <init-param>

     <param-name>config/acctmgmt</param-name>

     <param-value>/WEB-INF/struts-acctmgmt.xml</param-value>

   </init-param>

   <init-param>

     <param-name>debug</param-name>

     <param-value>3</param-value>

   </init-param>

   <init-param>

     <param-name>detail</param-name>

     <param-value>3</param-value>

   </init-param>

   <load-on-startup>2</load-on-startup>

 </servlet>

2.  Struts-default.xml

引入tiles-defs.xml文件

<plug-inclassName="org.apache.struts.tiles.TilesPlugin" >

   <set-propertyproperty="definitions-config"

       value="/WEB-INF/tiles-defs.xml"/>

   <set-propertyproperty="moduleAware" value="false" />

</plug-in>

3.  tiles-defs.xml

定义tiels，创建tiles组件，配置模板资源

<tiles-definitions>

       <!--site layout -->

       <definitionname="siteLayout" path="/sitelayout.jsp">

              <putname="header" value="header.jsp" />

              <putname="main" value="mainLayout" />

              <putname="footer" value="footer.jsp" />

       </definition>

       <!--layout of main area -->

       <definitionname="mainLayout" path="mainlayout.jsp">

              <putname="sidepanel" value="sideLayout" />

              <putname="content" value="contents" />

       </definition>

       <!--layout of sidepane -->

       <definitionname="sideLayout" path="sidepanel.jsp">

              <putname="leftupper"value="../upper.jsp" />

              <putname="leftlower"value="../lower.jsp" />

       </definition>

       <!--layout of content area -->

       <definitionname="contents" path="contents.jsp">

              <putname="section1" value="" type="string" />

              <putname="section2" value="" type="string" />

              <putname="section3" value="" type="string" />

              <putname="section4" value="" type="string" />

              <putname="section5" value="" type="string" />

              <putname="section6" value="" type="string" />

       </definition>

</tiles-definitions>

4.  sidepanel.jsp

引用tiles，创建模板布局

<%@ tagliburi="/WEB-INF/struts-tiles.tld" prefix="tiles" %>

<table role="presentation"cellpadding="2" cellspacing="0">

 <tr>

    <tdvalign="top">     

     <table role="presentation">

        <tiles:insert attribute="leftupper"ignore="true"/>

       <tr>

         <td>

           <div>

             <tiles:insert attribute="leftlower" ignore="true"/>

           </div>

         </td>

       </tr>

     </table>

   </td>

 </tr>

</table>

5.  welcome.jsp

在jsp页面中使用tiles

<%@ tagliburi="/WEB-INF/struts-tiles.tld" prefix="tiles" %>

<tiles:insert definition="siteLayout"flush="true">

   <tiles:put name="pageTitle" type="string"value="Site Entrance" />

   <tiles:put name="pageHeader"type="string" value="" />

   <tiles:put name="content"type="string">

   <!-- page content goes here -->

   </tiles:put>

</tiles:insert>
