在JSP页面中，我尝试使用：

${title}

但我无法在JSP标题中获得字符串“Home”

请帮我解决这个问题！ ----编辑我的JSP页面----


${title}

使用平铺时，可以直接从平铺xml文件指定页面名称为了做到这一点，您需要执行以下操作

在定义中添加另一个名为title的属性

<definition name="index" template="/WEB-INF/jsp/partical/main.jsp">
    <put-attribute name="title" value="Index" />
    <put-attribute name="content" value="/WEB-INF/jsp/partical/index.jsp" />
</definition>

如果我能给你一个意见，我相信你没有充分利用ApacheTiles所能提供的潜力

ApacheTiles是一个框架，允许您不在每个页面中复制代码。因此，为网站创建一个基本布局非常重要，然后您可以更改每个页面中的主体

给你举个例子

模板：

<definition name="app.base" template="/WEB-INF/views/template.jsp">
        <put-attribute name="title" value="Not Found" />
        <put-attribute name="body" value="/WEB-INF/views/body.jsp" />
        <put-attribute name="footer" value="/WEB-INF/views/footer.jsp" />
        <put-list-attribute name="stylesheets_top">
            <add-attribute value="/resources/site/library/bootstrap/bootstrap.min.css" />
            <add-attribute value="/resources/site/library/font-awesome/font-awesome.min.css" /> 
        </put-list-attribute>   
        <put-list-attribute name="javascripts_bottom">
            <add-attribute value="/resources/js/jquery/jquery-1.12.0.min.js" />
            <add-attribute value="/resources/site/library/bootstrap/bootstrap.min.js" />
        </put-list-attribute>   
</definition>

<definition name="home" extends="app.base">
        <put-attribute name="title" value="Home" />
        <put-attribute name="body" value="/WEB-INF/jsp/home.jsp" />
        <put-list-attribute name="stylesheets_top" inherit="true">
            <add-attribute value="/resources/site/home/home.css" />
        </put-list-attribute>   
        <put-list-attribute name="javascripts_bottom" inherit="true">
            <add-attribute value="/resources/site/home/home.js" />
        </put-list-attribute>   
</definition>

扩展模板的页面：

<definition name="app.base" template="/WEB-INF/views/template.jsp">
        <put-attribute name="title" value="Not Found" />
        <put-attribute name="body" value="/WEB-INF/views/body.jsp" />
        <put-attribute name="footer" value="/WEB-INF/views/footer.jsp" />
        <put-list-attribute name="stylesheets_top">
            <add-attribute value="/resources/site/library/bootstrap/bootstrap.min.css" />
            <add-attribute value="/resources/site/library/font-awesome/font-awesome.min.css" /> 
        </put-list-attribute>   
        <put-list-attribute name="javascripts_bottom">
            <add-attribute value="/resources/js/jquery/jquery-1.12.0.min.js" />
            <add-attribute value="/resources/site/library/bootstrap/bootstrap.min.js" />
        </put-list-attribute>   
</definition>

<definition name="home" extends="app.base">
        <put-attribute name="title" value="Home" />
        <put-attribute name="body" value="/WEB-INF/jsp/home.jsp" />
        <put-list-attribute name="stylesheets_top" inherit="true">
            <add-attribute value="/resources/site/home/home.css" />
        </put-list-attribute>   
        <put-list-attribute name="javascripts_bottom" inherit="true">
            <add-attribute value="/resources/site/home/home.js" />
        </put-list-attribute>   
</definition>

上面的页面将同时包含父页面和子页面的属性

模板可能如下所示

<title><tiles:insertAttribute name="title" /></title>

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<%@ taglib prefix="tiles" uri="http://tiles.apache.org/tags-tiles"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>


<tiles:importAttribute name="stylesheets_top" />
<tiles:importAttribute name="javascripts_bottom" />
<!DOCTYPE html>
<html lang="en">

<head>

<title><tiles:insertAttribute name="title" /></title>

</head>
<body>
    <header>
        <!-- stylesheets top -->
        <c:forEach var="css" items="${stylesheets_top}">
            <link rel="stylesheet" type="text/css" href="<c:url value="${css}"/>">
        </c:forEach>
    </header>
    <div class="body">

        <tiles:insertAttribute name="body" />
    </div>
    <footer class="footer">
        <tiles:insertAttribute name="footer" />
    </footer>

</body>

<!-- scripts_bottom -->
<c:forEach var="script" items="${javascripts_bottom}">
    <script src="<c:url value="${script}"/>"></script>
</c:forEach>

</script>
</html>

请发布您的jsp@redflar3请f5页查看我的更新同一问题：${pageContext.request.contextPath}不返回项目名称页面是否加载成功或是否出现异常？如果您遇到异常，请将其发布。并发布控制器类的其余部分。

<definition name="home" extends="app.base">
        <put-attribute name="title" value="Home" />
        <put-attribute name="body" value="/WEB-INF/jsp/home.jsp" />
