Blocking main thread

Camel applications extending FatJarRouter by default blocks the main thread of the application. It means that after you start your fat jar, your application waits for Ctrl+C signal and doesn't exit immediately. If you would like to achieve similar behavior for non-FatJarRouter applications, retrieve CamelSpringBootApplicationController bean from your ApplicationContext and use the former to block the main thread of your application using CamelSpringBootApplicationController#blockMainThread() method.

public static void main(String... args) {
    ApplicationContext applicationContext = new SpringApplication(MyCamelApplication.class).run(args);
    CamelSpringBootApplicationController applicationController =
            applicationContext.getBean(CamelSpringBootApplicationController.class);
    applicationController.blockMainThread();
}
