Read Console input on spring boot with tomcat

Question

Is it possible to read console input just before the embedded tomcat on the spring boot starts? The supposedly application flow is, request username and password from the user,

Answer 1

If you want to full log with console input like logger + System.out.println() outputs, then you have to use

nohup java -jar yourJarFile.jar admin password >> fullLogOutput.log &

Another issue:

the problem is when I close the console(SSH on linux) the process stops.

So you want to run your jar file as background process. You can't stop it with your console closing. Just add & symbol after full command, it will not stop. You can use the following command.

nohup java -jar yourJarFile.jar &

For taking full log with console output

nohup java -jar yourJarFile.jar >> fullLogOutput.log &

The & symbol is used to run the program in the background.

The nohup utility makes the command passed as an argument run in the background even after you log out.

Stopping/Killing the back-end process:

For stopping the background process, use ps -aux to get the id and then kill (id number)

ps -aux | grep yourJarFile.jar

You will get the id number. To kill that

sudo kill -9
