2. Eclipse runs the web project and reports an error message:
Several ports (8005, 8080, 8009) required by Tomcat v8.5 Server at localhost are already in use. The server may already be running in another process, or a system process may be using the port. To start this server you will need to stop the other process or change the port number(s).
The reason for the error is: the port is occupied.
The main reason for the error is: when tomcat starts, closing eclipse directly will cause the port to be occupied.
Solution:
In the tomcat directory, find the shutdown.bat in the bin folder and double-click to execute it, then go to eclipse to start tomcat and it will be successful!
