Сегодня я начал новый проект с Spring Boot (простой проект MVC).
Никогда не использовал Spring Boot с Thymeleaf, но с успехом использовался в качестве REST-сервера с аннотациями @Async и @EnableAsync (только создает и использует JSON).
Все работает отлично (в настоящее время только экран входа в систему), но когда я добавляю аннотацию @EnableAsync, «внутренний» сервер (Tomcat) не отвечает ни на один запрос (соединение отказано).
Если я уберу @EnableAsync, все снова будет работать идеально.
Ниже приведен журнал запуска без @EnableAsync:

просматривая журнал с включенной асинхронностью, я не вижу SimpleUrlHandlerMapping и RequestMappingHandlerAdapter.
Последняя строка привлекла мое внимание No task executor bean found for async processing: no bean of type TaskExecutor and no bean named 'taskExecutor' either, поэтому я использовал следующий код:
@Bean
public TaskExecutor threadPoolTaskExecutor() {
ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
executor.setCorePoolSize(4);
executor.setMaxPoolSize(4);
executor.setThreadNamePrefix("p2j");
executor.initialize();
return executor;
}
теперь строка о «нет bean-объекта типа TaskExecutor» не появляется и получает две новые записи в журнале:
2018-05-02 17:01:25.521 INFO 14084 --- [ restartedMain] o.s.s.concurrent.ThreadPoolTaskExecutor : Initializing ExecutorService
2018-05-02 17:01:25.525 INFO 14084 --- [ restartedMain] o.s.s.concurrent.ThreadPoolTaskExecutor : Initializing ExecutorService 'threadPoolTaskExecutor'
но сервер не отвечает ни на один запрос.
PS:
это основной класс:
@SpringBootApplication
@EnableAutoConfiguration
@EnableWebMvc
public class Portal2jApplication {
public static void main(String[] args) {
SpringApplication.run(Portal2jApplication.class, args);
}
}
Обновление:
Вот мой интерфейс хранилища:
@Repository
public interface UsuarioRepo extends MongoRepository<Usuario, String> {
@Async
CompletableFuture<Usuario> findByEmail(String email);
}
Почему-то я не помню: P, я использовал аннотацию @Async на интерфейсе, и в соответствии с этой страницей: http://www.baeldung.com/spring-async, @Async должен применяться к публичным методам только .
Удалил @Async из хранилища и использовал в правильном месте (в Service), все снова работает отлично. Не знаю, действительно ли это «ошибка»!
