阅读更多

步骤-：复习jsp：include

        

        1，所需jsp文件--->Header.jsp; Left.jsp; Content.jsp; Foot.jsp ; index.jsp

        2, Header.jsp; Left.jsp; Content.jsp; Foot.jsp 这四个jsp文件内容一样，只是单词不同。

    这里亮出

Header.jsp

//////////////////////////

              <%@page contentType="text/html; charset=utf-8" %>
              <html>
                 <head>
                    <title>Header.jsp</title>
                 </head>
                 <body>
                    <p align="center">Header</p>
                 </body>
                 </html>
///////////////////////////

           3,写index.jsp

index.jsp

///////////////////////////

                 <%@page contentType="text/html; charset=utf-8" %>
                 <html>
                 <head>
                     <title>index.jsp</title>
                  </head>
                  <body>
                     <table>
                        <tr>
                            <td colspan="2"><jsp:include flush="true" page="Header.jsp"/></td>
                         </tr>
                      <tr>
                             <td><jsp:include flush="true" page="Left.jsp"/></td>
                             <td><jsp:include flush="true" page="Content.jsp"/></td>
                       </tr>
                        <tr>
                              <td colspan="2"><jsp:include flush="true" page="Foot.jsp"/></td>
                        </tr>
                      </table>
                    </body>
                    </html>

 

步骤二：正题

             

           1，-->   Add Struts 

           2, -->增加两个jsp文件 one.jsp; two.jsp 具体内容同Header.jsp

           3, -->  在web.xml中配置tld

/////////////////////////////

                   <jsp-config>
                       <taglib>
                           <taglib-uri>/WEB-INF/struts-tiles</taglib-uri>
                           <taglib-location>/WEB-INF/struts-tiles.tld</taglib-location>
                       </taglib>
                    </jsp-config>

////////////////////////////  

 

                       4,  -->在struts-config.xml中加入tiles插件

///////////////////////////////////

                           <plug-in className="org.apache.struts.tiles.TilesPlugin">
                                <set-property property="definitions-config"
                                          value="/WEB-INF/tiles-defs.xml" />
                                <set-property property="definitions-parser-validate"
                                           value="true" />
                            </plug-in>

//////////////////////////////////

 

                            5,-->完成tiles-defs.xml

///////////////////////////////////

<?xml version="1.0" encoding="utf-8" ?>
<!DOCTYPE tiles-definitions PUBLIC
"-//Apache Software Foundation//DTD Tiles Configuration 1.1//EN"
"http://jakarta.apache.org/struts/dtds/tiles-config_1_1.dtd">

<tiles-definitions>
 <definition name="index-definition" path="/index_tiles.jsp">
  <put name="header" value="Header.jsp"/>
  <put name="left" value="Left.jsp"/>
  <put name="content" value=""/>
  <put name="foot" value="Foot.jsp"/>
 </definition>
 <definition name="one-definition" extends="index-definition">
  <put name="content" value="one.jsp"></put>
 </definition>
 <definition name="two-definition" extends="index-definition">
  <put name="content" value="two.jsp"></put>
 </definition>
</tiles-definitions>

///////////////////////////////////

 

                           6,-->写one-definition 的模板文件index_tiles.jsp

////////////////////////////////////

<%@page contentType="text/html; charset=utf-8" %>
<%@taglib uri="/WEB-INF/struts-tiles" prefix="tiles" %>
<html>
  <head>
 <title>index_tiles.jsp</title>
  </head>
  <body>
    <table>
     <tr>
      <td colspan="2"><tiles:insert attribute="header"/></td>
     </tr>
     <tr>
      <td><tiles:insert attribute="left"/></td>
      <td><tiles:insert attribute="content"/></td>
     </tr>
     <tr>
      <td colspan="2"><tiles:insert attribute="foot"/></td>
     </tr>
    </table>
  </body>
</html>

///////////////////////////////////

 

                            7,-->加一个ForwardAction配置， 这里只举one的例子

///////////////////////////////////

<action path="/toOne"
     type="org.apache.struts.actions.ForwardAction"
     parameter="one-definition"/>

//////////////////////////////////

                   

                            8，-->运行 http://localhost:8080/【项目名】/toOne.do
