How to create Spring Boot app as Ubuntu service?

1. Create service named employee using vi command

   sudo vim /etc/systemd/system/employee.service
   

2. Copy paste the following content into the file and make sure to change the ExecStart command arguments

   [Unit]
   Description=Employee Spring Boot application service
   
   [Service]
   User=ubuntu
   ExecStart=/usr/bin/java -Dspring.profiles.active=prod -Dusername="admin" -Dpassword="Password129388" -jar /home/ubuntu/Employee/target/employee-0.0.1-SNAPSHOT.jar 
   ExitStatus=143
   
   TimeoutStopSec=10
   Restart=on-failure
   RestartSec=5
   
   [Install]
   WantedBy=multi-user.target
   

3. Enable the service

   sudo systemctl enable employee
   

4. Start the service

   sudo systemctl start employee
   

5. Reload system daemon

   sudo systemctl daemon-reload
   

6. Check the service status

   sudo systemctl status employee 
   

7. Check service logs using the following command

   sudo journalctl -u employee.service --no-pager
   

On Ubuntu 20.04, the systemd does not recognize ExitStatus key with error message: Unknown key name 'ExitStatus' in section 'Service', ignoring.. In this case, you might be change ExitStatus to SuccessExitStatus.

- ExitStatus=143
+ SuccessExitStatus=143
