未知标签图块：insertAttribute

Question

我正在尝试使用 Tiles 在 JSP 页面中显示 div，但 Eclipse 向我显示如下警告：

Unknown tag (tiles:insertAttribute)

这是我的index.jsp：

<nav class="navbar navbar-inverse">     
    <tiles:insertAttribute name="header" />
</nav>
<!--  Main container  -->
<div class="container-fluid text-center">
    <div class="row content">
<!-- Right menu -->     
        <div class="col-sm-2 sidenav">
            <tiles:insertAttribute name="menu" />
        </div>

这是我的tiles.xml：

<?xml version="1.0" encoding="UTF-8" ?>

<!DOCTYPE tiles-definitions PUBLIC
   "-//Apache Software Foundation//DTD Tiles Configuration 2.0//EN"
   "http://tiles.apache.org/dtds/tiles-config_2_0.dtd">
<tiles-definitions>
    <definition name="index" template="/index.jsp">
        <put-attribute name="title" value="" />
        <put-attribute name="header" value="/Header.jsp" />
        <put-attribute name="menu" value="/Menu.jsp" />
        <put-attribute name="body" value="/Body.jsp" />
        <put-attribute name="footer" value="/Footer.jsp" />
    </definition>

这在我的web.xml:

<listener>
    <listener- class>org.apache.struts2.tiles.StrutsTilesListener</listener-class>
</listener>
<context-param>
    <param-name>tilesDefinitions</param-name>
    <param-value>/WEB-INF/tiles.xml</param-value>
</context-param>

Answer 1

您误解了项目使用的文件。 index.jsp 不应包含任何菜单内容。最好将其命名为head 或menu tile。

要在 JSP 中为标签使用 tiles: 前缀，您应该定义一个标签库：

<%@ taglib prefix="tiles" uri="http://tiles.apache.org/tags-tiles" %>
