【问题描述】：
我有一个带有 http 和 https 端口的 tomcat 8 服务器。所有的 jsp 文件在 http 上运行良好，但在 https 上，jsp 标签正在输出到页面，我看到了这样的东西。
<%@ page language="java" pageEncoding="UTF-8" contentType="text/html;charset=utf-8"%> <%@ page import="java.io.*,java.util.*,java.sql.*"%>
...
我不确定问题的根本原因是什么，虽然它看起来像是一个 tomcat 配置问题。我一直在查看我的 tomcat 配置文件，以防有什么不合适的地方，但据我所知，它似乎大部分都很好。可能是什么问题？
jsp 标签格式正确。 https 端口连接到弹性负载均衡器，我很确定此时已正确设置。
对于它的价值，这是我在 server.xml 中为连接器所拥有的东西
<Connector port="8080" proxyPort="80" proxyName="www.pckit.org"
protocol="HTTP/1.1"
connectionTimeout="20000" />
<Connector port="443" proxyPort="443"
protocol="HTTP/1.1"
maxThreads="150" scheme="https" secure="true"/>
<Connector port="8009" enableLookups="false" protocol="AJP/1.3" redirectPort="443" />
这是 web.xml 中的 jsp servlet
<servlet>
<servlet-name>jsp</servlet-name>
<servlet-class>org.apache.jasper.servlet.JspServlet</servlet-class>
<init-param>
<param-name>fork</param-name>
<param-value>false</param-value>
</init-param>
<init-param>
<param-name>xpoweredBy</param-name>
<param-value>false</param-value>
</init-param>
<load-on-startup>3</load-on-startup>
</servlet>
我还在 catalina 日志文件中发现了这个输出，这可能是相关的。
