velocity小结

  跟freemarker差不多,不错的东西.

1 配置
    　把velocity的toolbox.xml放到web-inf下，把velocity.properties放到web-inf下

２　跟spring整合
  <servlet>
    <servlet-name>velocity</servlet-name>
    <servlet-class>
         org.apache.velocity.tools.view.servlet.VelocityViewServlet
    </servlet-class>                                           
    <init-param>
      <param-name>org.apache.velocity.toolbox</param-name>
      <param-value>/WEB-INF/toolbox.xml</param-value>     
    </init-param>     
    <init-param>
      <param-name>org.apache.velocity.properties</param-name>
      <param-value>/WEB-INF/velocity.properties</param-value>
    </init-param>                                              
    <load-on-startup>10</load-on-startup>
  </servlet>
  <!-- Map *.vm files to Velocity -->
  <servlet-mapping>
    <servlet-name>velocity</servlet-name>
    <url-pattern>*.vm</url-pattern>     
  </servlet-mapping>

 

3 　常用的用法
　　　 #if($userinfo.hasPermission(1))

　　　　　．．．．

　　　　#end

       <input type="text" name="roleName" maxlength="15" value="$!role.getRoleName()" class="inputStyle" disabled>

       #foreach($fj in $fjList)
        <tr height=25>
          <td align=left>&nbsp;&nbsp;&nbsp;<a href="..$!fj.getPath()$!fj.getSite()/$!fj.getFileName()"  target="RithtFrame">$!fj.getTitle()</a></td>
        </tr>
   #end

 

    #set ($i=1)
      #foreach ($role in $page.getList())
       <td >$!i</td>

     ....

     #set ($i=$i+1)
      #end
