How Can I Monitor Directories After Spring Boot Application Start?

Monitoring Directories after Spring Boot Initialization

To monitor a directory for changes after your Spring Boot application starts, consider utilizing the ApplicationReadyEvent. This event triggers once the application is fully initialized and ready to handle HTTP requests.

The following code snippet demonstrates how to use the ApplicationReadyEvent listener:

<code class="java">@EventListener(ApplicationReadyEvent.class)
public void doSomethingAfterStartup() {
    System.out.println("hello world, I have just started up");
}</code>

The ApplicationReadyEvent fires after the @Autowired annotations have been set, ensuring that your services are ready for use. This approach provides a reliable and efficient way to execute code once your Spring Boot application is fully operational.

By utilizing the ApplicationReadyEvent, you can effectively monitor directories or perform other tasks after your application has successfully started, ensuring proper system initialization and timely event handling.
