[JAVA] What to do if tomcat process remains when tomcat is stopped in eclipse

If you stop tomcat in Eclipse and then start it again, you will get an error message stating that the port is being used, or in the case of Spring boot, "The Tomcat connector configured to listen on port 8080 failed to start. The port may already. The message "be in use or the connector may be misconfigured." May appear on the Eclipse console. These errors occur when the tomcat process remains after stopping tomcat. Therefore, in order to start tomcat on the same port again, it is necessary to stop the tomcat process once. Here, we will explain three ways to stop the tomcat process. The following environment is assumed.

--Environment

OS: macOS Mojave Eclipse version: Photon Release (4.8.0) tomcat8

How to stop tomcat process

--Stop the process in Activity Monitor.

  1. Open Activity Monitor.
  2. Look for the process name "java" displayed in the Activity Monitor. (Hover over Activity Monitor and press the "j" key to find it.)
  3. Double-click on "java" to bring up a window, then press the exit button for that window.
  4. When the message "Are you sure you want to end this process?" Is displayed, press the end button.

--Check the PID of the process with the top command and exit.

  1. Open terminal.
  2. Execute the following command on the terminal screen.
> top | grep java

Then, the process of "java" is displayed, and the PID is displayed on the far left, so copy it. 3. Execute the following command.

> kill <Copyed PID>

--Specify the process name with the pkill command and exit.

  1. Execute the following command.
> pkill java

that's all. I think that some people will fall in love with tomcat when it's just touched, so I hope it helps.
