Question

=“”

我想显示Authenticated user's名字和姓氏。我将相关的代码段放在Header.jsp中，并将其包含在另外两个jsp页面Index.jsp和News.jsp中。

当Header.jsp中包含News.jsp时，它会正常显示并显示经过身份验证的用户的名字和姓氏，但是当它包含在Index.jsp m时，它就不会什么都没有。我的页面结构看起来像打击：

header.jsp中

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

       <div class="usertext">
        <span id="loginedUserFullname">
             <sec:authorize access="isAuthenticated()">
               <sec:authentication property="principal.firstname" /> 
                      <sec:authentication property="principal.lastname" />
                  <span class="welcome">welcome</span>
                  <a class="logout" href='/view/cpanel/Logout.jsp'>(loge out)</a>
                  </sec:authorize>
         </span>

 </div>
</nav>

的index.jsp

<%@ page contentType="text/html; charset=UTF-8" language="java" pageEncoding="UTF-8" isELIgnored="false"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<%@ taglib prefix="spring" uri="http://www.springframework.org/tags"%>
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<meta name="keywords" content="">
<meta name="description" content="">
<jsp:include page="/includes/front/Head.jsp"></jsp:include>
<title></title>
</head>
<body>
    <jsp:include page="/includes/front/Header.jsp"></jsp:include>
    <jsp:include page="/includes/front/Scripts.jsp"></jsp:include>
</body>

News.jsp

<%@ page contentType="text/html; charset=UTF-8" language="java" pageEncoding="UTF-8" isELIgnored="false"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<%@ taglib prefix="spring" uri="http://www.springframework.org/tags"%>
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<meta name="keywords" content="">
<meta name="description" content="">
<jsp:include page="/includes/front/Head.jsp"></jsp:include>
<title></title>
</head>
<body>
    <jsp:include page="/includes/front/Header.jsp"></jsp:include>
    <jsp:include page="/includes/front/Scripts.jsp"></jsp:include>
</body>

在{。{1}}中哪些在Index.jsp中无效？
