Question

我正在使用taglib接近我的目标。我的taglib文件编写如下：

 <%@ attribute name="header" fragment="true" required="false" %>
 <%@ attribute name="footer" fragment="true" required="false" %>
 <%@ attribute name="styles" fragment="true" required="false" %>
 <%@ attribute name="scripts" fragment="true" required="false" %>

 <!DOCTYPE html>
<html>
<head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
    <meta charset="utf-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0">

    <link rel="stylesheet" href="../lib/bootstrap-paper/bootstrap.css" />
    <link rel="stylesheet" href="../lib/toastr/toastr.css" />
    <link rel="stylesheet" href="../lib/sweetalert/dist/sweetalert.css" />
    <link rel="stylesheet" href="../lib/famfamfam-flags/dist/sprite/famfamfam-flags.css" />
    <link rel="stylesheet" href="../lib/slick/slick.css" />
    <link rel="stylesheet" href="../lib/slick/slick-theme.css" />

    <link rel="stylesheet" href="../css/main.css" />
    <link rel="stylesheet"  href="../Content/sweetalert.css"/>
    <%--<jsp:invoke fragment="styles" />--%>
            <script src="//cdn.bootcss.com/angular.js/1.2.9/angular.js"></script>
    <script src="//cdn.bootcss.com/angular.js/1.2.9/angular-route.js"></script>
</head>

<body>
        <div id="pageheader">

        <jsp:invoke fragment="header" />
    </div>
  <div id="body" class="body-content">
<jsp:doBody />
</div>
<div id="pagefooter">
    <jsp:invoke fragment="footer" />
</div>

<jsp:invoke fragment="scripts" />
</body>

我的请求页面如下：

<%@ page language="java" import="java.util.*,com.ppdai.vip.dto.*"   pageEncoding="UTF-8" isELIgnored="false" %>
<%@ page import="com.ppdai.user.tuple.Tuple" %>
<%@ page import="ppdai.user.web.util.PropertyUtil" %>
<%@taglib prefix="t" tagdir="/WEB-INF/tags" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions"%>

<%

String title="首页";
   List<HomePageAdDto> bannerList=
        (List<HomePageAdDto>)request.getAttribute("IndexAdBanner");
    List<GoodsTypeDto> goodTypes=(List<GoodsTypeDto>)request.getAttribute("GoodTypes");
   String ssoKey=PropertyUtil.getSsoKey();
   String callBackUrl= PropertyUtil.getCallBackUrl();
  String requestUrl=request.getRequestURL().toString();

%>

 <t:genericpage>

  <%--<jsp:attribute name="styles">--%>
  <%--</jsp:attribute>--%>

  <jsp:attribute name="header">
  <jsp:include page="view/header.jsp" />
  </jsp:attribute>


  <jsp:body>
    1111
</jsp:body>
 <jsp:attribute name="footer">
    <jsp:include page="view/footer.jsp" />
  </jsp:attribute>
 </t:genericpage>

请求springmvc控制器的操作时发生异常：

我的文件结构如下：

我的pom参考如下：

 <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>javax.servlet-api</artifactId>
        <version>3.1.0</version>

Answer 1

我解决了，因为我无法在<jsp:body>中包含html和其他代码，使用<jsp:attribute>不会给我错误。

jsp：attribute必须是标准或自定义操作的子元素
