Jsp 包括不工作：找不到文件，状态 500

Question

我有这样的目录结构：

正在尝试将 header.jsp 包含在 home.jsp 中，如下所示：

<%--
  Created by IntelliJ IDEA.
  User: Irina
  Date: 31.03.20
  Time: 20:58
  To change this template use File | Settings | File Templates.
--%>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>Title</title>
</head>
<body>
<jsp:include page="${pageContext.request.contextPath}/shared/header.jsp" />
<a href="${pageContext.request.contextPath}/login">Login</a>
<a href="${pageContext.request.contextPath}/signup">Signup</a>

</body>
</html>

失败并出现 org.apache.jasper.JasperException: javax.servlet.ServletException: File [/comediansapp/shared/header.jsp] not found 错误。我做错了什么？

Answer 1

提供相对于当前页面的路径。尝试：

<jsp:include page="shared/header.jsp"/>

${pageContext.request.contextPath} 是您的应用程序的当前上下文路径是 comediansapp 因此它将尝试在路径 /comediansapp/shared/header.jsp

请检查：

我试过的完整示例：

index.jsp

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>Title</title>
</head>
<body>
<jsp:include page="shared/header.jsp" />
<a href="${pageContext.request.contextPath}/login.jsp">Login</a>
<a href="${pageContext.request.contextPath}/signup.jsp">Signup</a>

</body>
</html>

shared/header.jsp

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>

<nav style="height:50px; background:red;">
    <strong> JSP!!! </strong>
</nav>
