Java how to stop spring boot application

To stop a Spring Boot application, you can use the CTRL + C keyboard shortcut if the application is running in the terminal, or use the kill command if the application is running as a background process.

Alternatively, you can use the SpringApplication.exit method to stop the application. This method will shutdown the application context and stop all the running threads.

Here's an example of how you can use the SpringApplication.exit method to stop a Spring Boot application:

@SpringBootApplication
public class MyApplication {
    public static void main(String[] args) {
        ConfigurableApplicationContext context = SpringApplication.run(MyApplication.class, args);
        // ...
        context.close();
        SpringApplication.exit(context, () -> 0);
    }
}

This code will close the application context and stop the application using the SpringApplication.exit method.

Note that the SpringApplication.exit method should only be used in cases where the application needs to be stopped abruptly, such as when an unrecoverable error occurs. In normal circumstances, you should use the CTRL + C keyboard shortcut or the kill command to stop the application.
