`System.exit(0)` could be dangerous. I suggest using this instead: `SpringApplication.exit(ctx)`

Is there a reason here? Would the SpringApplication do things to close up services and so on?

Yes, this does not always matter, but sometimes there are services which need a headsup before being closed to finalize something, like flush to a log file or alike. `SpringApplication.exit` first closes the context, properly calling all the shutdown hooks, then shuts down the application.

All of what you said works perfectly. Thanks
