参考技术A 方法/步骤 https://www.devexpress.com/去下载安装插件。如果安装winform相关需要30分钟左右。（正版试用期30天） 安装后会出现Demo Center 14.1的一个应用程序。打开可以看到提供给开发者的一些例子。

Apache Tiles 3：org.apache.tiles.template.NoSuchAttributeException：找不到属性'title'

我正在使用Tiles 3为我的Spring网站制作模板。 layout.jsp结合了header.jsp，body和footer.jsp。在header.jsp中，我有一个我想通过tile定义文件（tiles.xml）中的put-attribute将标题传递给index.jsp。但是当我运行index.jsp时，我得到了

org.apache.tiles.template.NoSuchAttributeException: Attribute 'title' not found

以下是我的代码：

tiles.xml

我做错了什么？

答案

根据您的瓷砖定义，

<tiles:insertAttribute name="{attribute-name}" />

只能用在

 template="/WEB-INF/jsp/layout.jsp"

当您尝试使用header.jsp时，它失败了。更新代码以使用layout.jsp并将其从其他JSP文件中删除。
