我不明白為什么這個錯誤來了！

2 個解決方案

解決方案1
 1 已采納  2016-02-17 04:53:23

首先，將“ view”文件夾移動到“ WEB-INF”目錄並更改以下映射

嘗試在tile.xml中更改以下映射 

<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>

到以下 

<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>

每個控制器的返回值將與每個與jsp相關聯的圖塊定義映射，以在模板中呈現為主體。 這就是為什么我們需要為“ home”添加映射。

如下創建template.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>template</Title>
</head>
<body>
<tiles:insertAttribute name="header" />
</body>
</html>

然后你的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，您不需要插入屬性“ header”。 瓷磚將為您做到這一點。

並刪除InternalResourceViewResolver

如下更改您的圖塊： 

<tiles-definitions>
<definition name="base.definition" template="/WEB-INF/view/mainTemplate.jsp">
    <put-attribute name="title" value=""></put-attribute>
    <put-attribute name="header" value="/WEB-INF/view/header.jsp"></put-attribute>      
    <put-attribute name="body" value=""></put-attribute>
    <put-attribute name="footer" value="/WEB-INF/view/footer.jsp"></put-attribute>
</definition>
<definition extends="base.definition" name="home">
    <put-attribute name="title" value="Home Page"></put-attribute>
    <put-attribute name="body" value="/WEB-INF/view/home.jsp"></put-attribute>
</definition>

創建/WEB-INF/view/mainTemplate.jsp 

<%@ taglib uri="http://tiles.apache.org/tags-tiles" prefix="tiles"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title><tiles:insertAttribute name="title" ignore="true" /></title>
</head>
<body>

  <div id="header">
     <!-- Header Tiles -->
     <tiles:insertAttribute name="header" />
  </div>


  <div id="section">
     <!-- Body Tiles -->
     <tiles:insertAttribute name="body" />
  </div>

  <div id="footer">
     <tiles:insertAttribute name="footer" />
  </div>
  <!-- footer Tiles -->    
</body>
</html>

然后創建您的/WEB-INF/view/home.jsp。 home.jsp的內容將自動出現在mainTemplate.jsp的主體中
