Question

我尝试使用磁贴在div中显示jsp页面，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>

这是我的 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>

编辑：这是我的 pom.xml 的一部分，如果需要更多信息，请问我。

您误解了项目使用的文件。 Datacenter: dc1 =============== Status=Up/Down |/ State=Normal/Leaving/Joining/Moving -- Address Load Tokens Owns (effective) Host ID Rack DN 10.249.55.108 283.54 KiB 256 100.0% 619242db-f0bd-4492-aeb6-2bb0ebfe4733 rack1 Datacenter: dc2 =============== Status=Up/Down |/ State=Normal/Leaving/Joining/Moving -- Address Load Tokens Owns (effective) Host ID Rack UN 10.249.55.111 294.75 KiB 256 100.0% 6ebe897e-94e3-44e5-99dc-055beb633e74 rack1不应包含任何菜单内容。它应该更好地命名为index.jsp或head tile。

要在JSP中使用menu前缀标记，您应该定义一个taglib：

tiles:

未知标记切片：insertAttribute
