In the idea of using Tomcat configuration when the project started, there will always encounter service problems can not be closed properly.
You can use cmd command forcibly shut down Tomcat process. As follows:
1, first find the process ID PID 8080 occupied port is the number
CMD> netstat -ano | findstr 8080
this last one command output indicates the occupancy 8080 port number is how much of the process, here is my 7076
2, kill off the process
CMD> taskkill / F / PID 7076
So 8080 is released.
