Stop current running Spring boot in linux

Question

i am running a springboot application in linux.To run this springboot we use below command.

java -jar sssup-SNAPSHOT.jar &

This spring boot application makes an endpoint available which is then used by other services.

Now when the new version of .jar is available i have to stop the current running .jar and again run the above mentioned command.

Here my question is how to stop the current running sssup-SNAPSHOT.jar ?

Answer 1

Since you are running the process in the background you need to find its process first to kill it.

To find the process ID fire below command:

ps -ef | grep "sssup-SNAPSHOT.jar"

The output will look something like below:

 502  5980  5964   0 10:40AM ttys000 

Your second column is your process ID So, over here it is 5980. After copying that fire below command.

kill 5980

Just check again by firing ps -ef command that it gets killed or not. If it's not killed already than you can use -9 flag to force kill it. Like kill -9 <PID>

Answer 2

One way is to bring the background process to the foreground with the fg command and then press Ctrl+C. This will only work if you are in the same terminal where you ran the JAR file.

Another more reliable way is to use ps -a | grep java to find the process id of your app. Then you can do kill <PID> with that process id.
