Tomcat Startup error: Error running tomcat:address localhost:1099 is already in use

Tomcat Startup error: Error running tomcat:address localhost:1099 is already. This is a server where Tomcat did not shut down properly after the last boot or encountered an exception, and some of the threads did not shut down completely. This is where 1099 of the thread is not shut down, so the server does not start properly again, causing the Web project to run. This is obviously 1099 ports have been occupied, the solution is as follows:

Java is actually a thread that is not finished, and can be learned by viewing the process:

Execute command cmd---"Netstat-ano
You can see the PID:

And then through the command: tasklist know is the PID of which name: (actually can be directly based on this PID to find in the Task Manager)

Is that a java.exe process takes up

Then you can go to Task Manager to force him off:

Because I am the problem has been resolved, and then want to reproduce the resolution process, so the task manager will have another java.exe process, ignore it, turn off the corresponding to occupy the port number of the PID process is good

This will allow you to reboot the server.
