Apache Tiles 2.2.2将tiles-config.xml传递给JSP

我在所有页面中都有一个共同的标题，除了某些页面，其中有一些选项的标题的右侧。例如，我的标题的右侧将具有以下选项：块，撰写，编辑取决于页面。可以从tiles-config.xml中设置此headerShowIcons，然后在rhsHeader.jsp中使用它。Apache Tiles 2.2.2将tiles-config.xml传递给JSP

有没有什么办法让我可以通过从瓷砖-config.xml中rhsHeader.jsp一些值，并基于该值我想要显示的选项（即阻止，编辑或删除）

示例：如果我想向用户显示Compose选项，我只需从tiles-config.xml传递值（即headerShowIcons ='compose'）并在JSP中使用它。如果我想要显示Block，我将传递headerShowIcons ='block'，它将被rhsHeader.jsp读取以显示Block选项。我希望这将是更清晰

瓷砖-config.xml中

<definition name="*/*/*/*/*/index" template="/{1}/{2}/xyz/{4}/layouts/layout.jsp"> 
    <put-attribute name="lhsHeader" value="/{1}/{2}/xyz/s/headerWithBack.jsp" /> 
    <put-attribute name="rhsHeader" value="/{1}/{2}/xyz/s/rhsHeader.jsp"/> 
    <put-attribute name="body" value="/{1}/{2}/xyz/s/myProfile.jsp" /> 
</definition>

layout.jsp

<!-- What should I add here to meet the requirement --> 
<body> 
    <header> 
     <div> 
     <tiles:insertAttribute name="header"/> 
     <tiles:insertAttribute name="rhsHeader"/> 
     </div> 
    </header> 
    <div> 
     <tiles:insertAttribute name="body"/> 
    </div> 
    </body>

rhsHeader.jsp是这样的：

<tiles:useAttribute name="headerShowIcons" /> 
<div class="RHS"> 
<ul> 
<!-- I want to show the options (like- Block,Delete,etc) which will be passed from tiles-config.xml to rhsHeader.jsp (which here I have written it as headerShowIcons)--> 
    <c:choose> 
     <c:when test="${headerShowIcons eq 'refine'}"> 
      <li><a href="#" class="refine">Refine</a></li> 
     </c:when> 
     <c:when test="${headerShowIcons eq 'block'}"> 
      <li><a href="#" class="block">Block</a></li> 
     </c:when> 
     <c:when test="${headerShowIcons eq 'edit'}"> 
      <li><a href="javaScript:void(0);" class="edit">Edit</a></li> 
     </c:when> 
     <c:when test="${headerShowIcons eq 'delete'}"> 
      <li><a href="javaScript:void(0);" class="delete">Delete</a></li> 
     </c:when> 
     <c:otherwise> 
       <p>test</p> 
     </c:otherwise> 
    </c:choose> 
</ul>

我会选择做不同的方式，但如果它是你想要的，请参见下面的

瓷砖-config.xml中

<tiles-definitions> 
    <definition name="app.base" template="/WEB-INF/views/default/default.jsp"> 
     <put-attribute name="title" value="Not Found" /> 
     <put-attribute name="headerShowIcons" value="" /> 
     <put-attribute ..........> 
    </definition> 
    <definition name="home" extends="app.base"> 
     <put-attribute name="title" value="Home Page" /> 
     <put-attribute name="headerShowIcons" value="edit" /> 
     <put-attribute ..........> 
    </definition> 
</tiles-definitions>

回到Home.jsp

<c:set var="var"><tiles:insertAttribute name="headerShowIcons"/></c:set> 

<c:choose> 
    <c:when test="${'refine' == var}"> 
      <li><a href="#" class="refine">Refine</a></li> 
    </c:when> 
    <c:when test="${'block' == var}"> 
     <li><a href="#" class="block">Block</a></li> 
    </c:when> 
    <c:when test="${'edit' == var}"> 
     <li><a href="javaScript:void(0);" class="edit">Edit</a></li> 
    </c:when> 
    <c:when test="${'delete' == var}"> 
     <li><a href="javaScript:void(0);" class="delete">Delete</a></li> 
    </c:when> 
    <c:otherwise> 
     <p>test</p> 
    </c:otherwise> 
</c:choose>

如果您愿意，可以将其移至layout.jsp并相应地显示您的标题

我已经编辑了问题，我想这会更清楚了。 –

@ balboa_21看到更新回答 – QGA

请看问题的大胆部分。[有什么办法吗？] –

我终于找到了解决办法要做到这一点，我认为这可能有助于有人用这样的要求：

，我们将不得不使用

在headerLayout.jsp

<tiles:useAttribute name="whatToShow"/> 
    <header> 
    <div> 
     <tiles:insertAttribute name="lhsHeader" /> 
     <tiles:insertAttribute name="rhsHeader"> 
      <tiles:putAttribute name="whatToShow">${whatToShow}</tiles:putAttribute> 
     </tiles:insertAttribute> 
    </div> 
    </header> 
<div> 
    <tiles:insertAttribute name="body"/> 
</div>

在瓷砖，config.jsp中

<definition name="Header.*" template="/{1}/layouts/headerLayout.jsp"> 
    <put-attribute name="lhsHeader" value="/s/headerWithBack.jsp"/> 
    <put-attribute name="rhsHeader" value="/s/rhsHeader.jsp"/> 
    <put-attribute name="body" value=""/> 
    <put-attribute name="whatToShow" value="block" type="string"/> 
</definition> 
<!-- inside the definition under whatToShow, I just write whatever value(block,edit,delete,etc) I want to pass to the rhsHeader.jsp -->

在rhsHeader.jsp

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%> 
<tiles:useAttribute name="whatToShow"/> 
<div class="RHS"> 
<ul> 
    <c:choose> 
     <c:when test="${whatToShow eq 'refine'}"> 
      <li><a href="#" class="refine">Refine</a></li> 
     </c:when> 
     <c:when test="${whatToShow == 'block'}"> 
      <li><a href="#" class="block">Block</a></li> 
     </c:when> 
     <c:when test="${whatToShow eq 'edit'}"> 
      <li><a href="javaScript:void(0);" class="edit">Edit</a></li> 
     </c:when> 
     <c:when test="${whatToShow eq 'delete'}"> 
      <li><a href="javaScript:void(0);" class="delete">Delete</a></li> 
     </c:when> 
     <c:otherwise> 
       <p></p> 
     </c:otherwise> 
    </c:choose> 
    </ul> 
</div>

PS：我已经使用whatToShow代替headerShowIcons
