java - tomcat启动时，通常只允许每个套接字地址(协议(protocol)/网络地址/端口)使用一次？

Question

这是 server.xml 中我的连接器元素。我也尝试使用 8443 而不是 8484 但同样的错误。

<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经 Tomcat start up error 验证的端口(8484 或 8443) 。 我不确定真正的原因是什么？

Answer 1

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

您正在尝试在同一端口上打开两个监听套接字。

redirectPort 用于:

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.

它需要是一个与 port 指定的不同端口
