Sometimes when you run a Web project, you encounter an error running tomcat8:address localhost:1099 is already in, causing the Web project to run. This is obviously 1099 ports have been occupied, the solution is as follows:

The first step, the command prompt symbol, executes the command: Netstat–ano

Visible, the 1099-port process PID is 6072.

Step two, command prompt symbol, execute command: tasklist

Visible, the process that occupies the 8080 port is Java.exe
The third step, through Task Manager, terminates the process Java.exe

We're going to see 2 java.exe open, and it's all gone.

Fourth step, restart Tomcat to start normally
