Apache Tiles：管理CSS和JS资源

我有问题想办法解决这个问题。我想在某些需要的页面上插入某些CSS和JS文件。所以我做了这样的事情在我的瓷砖定义文件：Apache Tiles：管理CSS和JS资源

<definition name="datepickerScripts" template="/WEB-INF/jsp/insertScripts.jsp"> 
     <put-list-attribute name="scriptsList" cascade="true"> 
     <add-attribute value="js/jquery-ui.min.js" /> 
     <add-attribute value="js/setup-datepicker.js" /> 
     </put-list-attribute> 
    </definition> 

    <definition name="formValidationScripts" template="/WEB-INF/jsp/insertScripts.jsp"> 
     <put-list-attribute name="scriptsList" cascade="true"> 
     <add-attribute value="js/validate.min.js" /> 
     <add-attribute value="js/formValidationHelpers.js" /> 
     </put-list-attribute> 
    </definition> 
    <definition name="addUser" extends="layout"> 
     <put-attribute name="title" value="users.add" /> 
     <put-attribute name="content" value="/WEB-INF/jsp/addUser.jsp" /> 
     <put-attribute name="datepickerScriptBundle" type="definition"> 
      <definition extends="datepickerScripts" /> 
     </put-attribute> 
    </definition>

这是insertScripts.jsp代码：

<%@ taglib uri="http://www.springframework.org/tags" prefix="spring" %> 
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %> 
<%@ taglib uri="http://tiles.apache.org/tags-tiles" prefix="tiles"%> 
<%@ taglib uri="http://tiles.apache.org/tags-tiles-extras" prefix="tilesx" %> 

<spring:url value="/" var="url" /> 
<tilesx:useAttribute id="list" name="scriptsList" classname="java.util.List" /> 
<c:forEach var="item" items="${list}"> 
    <script type="text/javascript" src="${url}${item}"></script> 
</c:forEach>

所以我这样称呼它在我的baselayout页这是一个父ADDUSER页：

<tiles:insertAttribute name="datepickerBundleScript" ignore="true" />

的问题是，它抛出以下异常：

我很尴尬。我的代码没有问题。我刚刚删除<tiles:insertAttribute name="datepickerBundleScript" ignore="true" />后的注释代码，它工作。所以我想Tiles不会忽略JSP评论？

你应该自己回答。提问的问题，因为瓷砖的更多例子总是很好，尤其是工作的;） – Quaternion
