?? 由于web中的文件不能直接通過url方式讀取opencms的sites下的文件，所以必須繞個彎子解決。查閱了一下opencms的源代碼，我的解決思路如下：
?
第一 拷貝方式：
?
?? 1.第一次訪問時，根據opencms提供的接口，把文件從數據庫讀到java對象obj
?? 2.將obj對象拷貝到web中的對應目錄
?? 3.將web中的對應目錄的URL確定，即可直接調用。
?? 4.第二次及其以后訪問時，根據對象obj的最后修改時間屬性，確定是否需要重復1-3步驟。
參考源代碼：

第二、新增Resource Type方式
? 1.新建Resource Type，詳細請見前一篇文章
??2.在opencms控制臺，新增該類別的文件
? 3.調用相關API顯示出來，代碼如下
?
<%
????if?(getResourceCount(__cms,?"TEEMA_Ad/Home/Wide_Block_1/|teemaAd",?false)?>?0)?{?
%>??
????????????<cms:contentload?collector="allInFolderDateReleasedDesc"?param="TEEMA_Ad/Home/Wide_Block_1/|teemaAd"?editable="true">
????????????????????<%?
?????????????????if(bannerTextCount<1)?{
????????????????bannerTextCount++;
????????????%>
????????????????????????????<a?href='<cms:contentshow?element="URL"/>'?target="_blank">
??????????????????????????????<img?src="/eeonline/cms<cms:contentshow?element="Image/Image"/>"?width="440"?height="75">
????????????????????????????</a>
????????????<%???}?%>
??????????????????</cms:contentload>
????????</tr>
<%
????}?
%>??
?
歡迎提出新的意見！
