Java exec detects where the Tomcat service is in (normal, start or stop, stop state)

Thought: Check with cmd command

Normal operation: cmd/c net start outputs the list that has been started, compared to whether it is in the list

Start or stop in: cmd/c net start tomcat outputs relationship hints in start or stop

Stop state: Above two, is stop state

Extended:

Originally wanted to use cmd Startup.bat boot is tomcat, then this state (starting) is saved to the database

With cmd startdown.bat off is Tomcat, then this state (stopping) is saved to the database

It also takes time to start and shut down, to check if it's up or down, to detect if HTTP is accessible, a bit of a hassle, to add Tomcat to the service

It's better to judge.
