Description:

The Tomcat connector configured to listen on port 8097 failed to start. The port may already be in use or the connector may be misconfigured.

Verify the connector's configuration, identify and stop any process that's listening on port 8097, or configure this application to listen on another port.
这时,使用
ps -ef|grep 项目名,查看进程
kill -9 项目名
然后再进行重启就可以
