Question

我在Tomcat的根文件夹下有Jsp文件，我想要包含另一个放在webapps文件夹下的jsp文件。我正在尝试使用代码

    <%@page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <title>JSP Page</title>
    </head>
    <body>
        <h1>Hello World!</h1>
<jsp:include page="../docs/index.html"/>
    </body>
</html>

我收到以下异常

HTTP Status 500 - An exception occurred processing JSP page /trail.jsp at line 16

type Exception report

message An exception occurred processing JSP page /trail.jsp at line 16

description The server encountered an internal error that prevented it from fulfilling this request.

exception

13:     </head>
14:     <body>
15:         <h1>Hello World!</h1>
16: <jsp:include page="../docs/index.html"/>
17:     </body>
18: </html>

请帮我在tomcat的webapps文件夹下包含jsp。

提前致谢

Answer 1

webapps / doc /中的文件与trail.jsp不在同一个上下文中。您不能包含来自其他上下文的jsp。虽然根据代码，您尝试包含静态文件。如果这是正确的，请更新您的说明。

Answer 2

从目录WEB-INF/views（src/main/webapp/WEB-INF/views）

中试试

<jsp:include page="/WEB-INF/views/index.jsp" />

Webapp Structure
