Configuring asynchronous support  

To run everything, we need an entry point for our application with the following customized methods:

@EnableAsync                                                         // (1)@SpringBootApplication                                               // (2)public class Application implements AsyncConfigurer {   public static void main(String[] args) {      SpringApplication.run(Application.class, args);   }   @Override   public Executor getAsyncExecutor() {                              // (3)      ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();// (4)      executor.setCorePoolSize(2);      executor.setMaxPoolSize(100);      executor.setQueueCapacity(5);                                  // (5)       executor.initialize();      return executor;   }   @Override   public AsyncUncaughtExceptionHandler getAsyncUncaughtExceptionHandler(){      return new SimpleAsyncUncaughtExceptionHandler();              // (6)   }}
