my port 8080 in java Spring so never disconnects. The process remains open even if I stop the application. Which means that when I launch the project and restart it a second time after a code modification, I am shown that it is already listening. It's the same project. I therefore have to go to currport to stop the process each time a line of code changes if I restart the project. If I change the port in application.properties, all the ports that I indicate are displayed "already listening" while ultimately, currport does not find any process on these ports. So I waste a lot of time killing the 8080 process on currport between each launch OF THE SAME PROJECT, something I never did before, I have java on 2 other PCs and it doesn't do that, I can re-run a project without kill the process. When I launch my project, it listens on one port, as long as I don't stop it, whether I launch my project 1 time or 10 times, the listening is the same. I don't know what change there was, but it affects all my spring projects only on the 8080, all other projects which launch a web service on another port do not have this problem. I've never had this problem before.

even if I change the port in application.properties, it gives me the same problem, all the ports that I put are already listening while no process with these ports exists.
it is not another process which can be incriminated, because when I stop the process on port 8080 via currport, my project runs again, but I restart it just after, it gives me an error again because port busy, so before restarting my project which is already listening, I have to stop the process manually, can you imagine doing this every time you modify your code?
pressing the red button to stop the process has no effect. thanks
To solve this first you need to open your Command Line (cmd) and type:
netstat -ano | findstr :8080
This will identify the process ID that is using the 8080 port,
Then on the same comand line type the following command:
taskkill /PID yourProcessNumber /F
Where yourProcessNumber must be replaced by the process number you just identified previously.
I hope this helps
The number 31420 would be the process id number in my case [1]: https://i.sstatic.net/939uM.png
