Spring에서 Async 쓰는 방법

Question

안녕하세요. 오늘도 찾아오게되었네요...휴spring으로 @scheduled 어노테이션 사용해서 로직을 하나 짰는데요.예를들어 1초 반복인데 10초 sleep이 있다고 하면아시다시피 스레드 하나로 동작하기 때문에 1초마다 실행되지 않고 10초있다가 실행되잖아요.이를 보완하기 위해 @Async를 사용하려고했는데 개인 pc에서 이클립스로 실행할 땐 로그가 잘 찍히는데서버에 배포해서 확인하면 자꾸 에러가 납니다 ㅜㅠㅜㅜ테스트 예제코드라서 뭐 얼마 있지도 않아요...@Configuration @EnableAsync public class AsyncConfig{ @Bean(name = "threadPoolTaskExecutor") public Executor threadPoolTaskExecutor() { ThreadPoolTaskExecutor taskExecutor = new ThreadPoolTaskExecutor(); taskExecutor.setCorePoolSize(5); taskExecutor.setMaxPoolSize(10); taskExecutor.setQueueCapacity(10); taskExecutor.setThreadNamePrefix("Executor-"); taskExecutor.initialize(); return taskExecutor; } }@Service public class MyService { static Logger logger = LoggerFactory.getLogger("com.MyService "); @Async("threadPoolTaskExecutor") public void print(String message) { System.out.println(message); } }아직 @Scheduled는 사용도 안했는데 여기에서부터 에러가 찍힙니다.org.springframework.beans.factory.BeanCreationException:

감사하겠습니다.

@Scheduled 어노테이션을 사용하면 하나의 스레드에서 실행되나요? 제 기억으론 별도의 스케쥴링 스레드 풀이 있었던것 같은데요

설정에 setThreadNamePrefix 라인 지우고, async 어노테이션에 threadpooltaskexecutor 이거 지우세요. 그리고 서블릿에 async-supported true로 해야 비동기 어노테이션될텐데요.
