how to shutdown springboot immediately while configuration is wrong?

I have a question while developing my own components depending on autoconfiguration, and there are required critical parameters.

So I have a checking method in my component which annotated with @PostConstruct

If the configuration was wrong, I want this method to print the error log and shutdown application immediately just like if I set something wrong in springboot's basic configuration.

But the fact is, while using SpringApplication.exit(applicationContext)to shut down the application ,the application will remain running and stuck in somewhere and will not shut down.

the exception strack trace is shown below:

Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.

Well,after injection

    @Resource
    private ApplicationContext applicationContext

using ((ConfigurableApplicationContext)applicationContext).close() in a try catch block, shutting down the application after catching exceptions will solve the problem.

Are there more graceful ways to do so?
