camel-spring-boot - Make it easy to keep the JVM running

@SpringBootApplication
public class SampleCamelApplication {

    public static void main(String[] args) {
        ConfigurableApplicationContext ctx = new SpringApplicationBuilder().sources(SampleCamelApplication.class).run(args);

        // keep the JVM running as Camel uses only daemon threads in the sample
        CamelSpringBootApplicationController controller = ctx.getBean(CamelSpringBootApplicationController.class);
        controller.blockMainThread();
    }
}
