解决IDEA中：Error running Tomcat8: Address localhost:1099 is already in use
When I was running the web project today, it suddenly failed to run, and finally reported Error running Tomcat8: Address localhost:1099 is already in use
As a result, the web project cannot be run. After a look, it turns out that port 1099 is occupied. The solution is as follows:
First enter window+r into cmd and execute the netstat -ano command
In this way, the pid that occupies the port number of 1099 is 11036, and then we are executing the tasklist command
Furthermore, we can see that the process occupying port 8080 is java.exe, and then we open the task manager to terminate the process java.exe
Then restart Tomcat
