我不明白为什么会出现这个错误!

最佳答案

首先将“view”文件夹移动到“WEB-INF”目录并更改以下映射

尝试更改tiles.xml中的以下映射

<definition name="login" template="/view/home.jsp">
    <put-attribute name="title" value="" />
    <put-attribute name="header" value="/view/header.jsp" />
    <put-attribute name="body" value="" />
    <put-attribute name="footer" value="" />
</definition>

至以下内容

<definition name="base.definition" template="/WEB-INF/view/template.jsp">
    <put-attribute name="title" value="" />
    <put-attribute name="header" value="/WEB-INF/view/header.jsp" />
    <put-attribute name="body" value="" />
    <put-attribute name="footer" value="" />
</definition>


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

The return value of every controller will be mapped with each tiles definition which is associated with jsp to render as body in template. This is why we need to add mapping for 'home'.

创建template.jsp如下

<%@page contentType="text/html" pageEncoding="UTF-8"%>
<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form" %>
<%@ taglib prefix="spring" uri="http://www.springframework.org/tags" %>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions" %>
<%@ taglib prefix="tiles" uri="http://tiles.apache.org/tags-tiles" %>

<html>
<head>
    <Title>template</Title>
</head>
<body>
<tiles:insertAttribute name="header" />
</body>
</html>

然后是你的 home.jsp

<%@page contentType="text/html" pageEncoding="UTF-8"%>
<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form" %>
<%@ taglib prefix="spring" uri="http://www.springframework.org/tags" %>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions" %>
<%@ taglib prefix="tiles" uri="http://tiles.apache.org/tags-tiles" %>

<html>
<head>
    <Title>Home</Title>
</head>
<body>
</body>
</html>

在 home.jsp 中，您不需要插入属性“header”。瓷砖将为您完成此操作。

并删除InternalResourceViewResolver

关于java - Spring Web MVC Tiles 属性 'header' 未找到，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/35447784/
