Apache Tiles 3：org.apache.tiles.template.NoSuchAttributeException：找不到属性“标题”答案

【问题标题】：Apache Tiles 3: org.apache.tiles.template.NoSuchAttributeException: Attribute 'title' not foundApache Tiles 3：org.apache.tiles.template.NoSuchAttributeException：找不到属性“标题”
【发布时间】：2017-07-22 14:54:31
【问题描述】：

我正在使用 Tiles 3 为我的 Spring 网站制作模板。 layout.jsp 由 header.jsp、body 和 footer.jsp 组合而成。在 header.jsp 中，我有一个我想通过平铺定义文件 (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

下面是我的代码：

tiles.xml

我做错了什么？

【问题讨论】：

标签： jsp attributes tiles

【解决方案1】：

根据您的图块定义，

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

只能用在

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

当您尝试在 header.jsp 中使用时，它失败了。更新您的代码以使用 layout.jsp 中的内容并将其从其他 JSP 文件中删除。
