这是我在 server.xml 中的连接器元素.我也尝试使用 8443 而不是 8484 但同样的错误.

Here is my connector element in server.xml. I also tried using 8443 instead of 8484 but same error.

<Connector 
  SSLEnabled="true" 
  acceptCount="100" 
  connectionTimeout="20000" 
  executor="tomcatThreadPool" 
  keystoreFile="D:/.keystore" 
  keystorePass="changeit" 
  maxKeepAliveRequests="15" 
  port="8484" 
  protocol="HTTP/1.1" 
  redirectPort="8484" 
  scheme="https" 
  secure="true" 
  allowUnsafeLegacyRenegotiation="true"/>

我确信没有其他应用程序正在使用端口(8484 或 8443)，经 Tomcat 启动错误验证.我不确定真正的原因是什么?

i am sure no other app is using ports(8484 or 8443) as verified with Tomcat start up error. i am not sure what is the actual cause ?

推荐答案

port="8484" 
...
redirectPort="8484" 

您正试图在同一个端口上打开两个侦听套接字.

You're attempting to open two listening sockets on the same port.

redirectPort 用于:

如果此连接器支持非 SSL 请求，并且收到了一个匹配的 <security-constraint> 请求.需要 SSL 传输，Catalina 会自动将请求重定向到此处指定的端口号.

If this Connector is supporting non-SSL requests, and a request is received for which a matching <security-constraint> requires SSL transport, Catalina will automatically redirect the request to the port number specified here.

它需要与 port
