문제

문서에 achord 서비스 수명주기 RegistryShutdownListener를 구현하고 내 리소스를 정리할 수 있어야합니다 (이 경우 ThreadPool을 종료) 예외를 던지고 셧다운 리스너를 수행하기 위해 내 서비스를 다시 시작하려고하는 것 같습니다!?

package.myservice.java :

public class MyService implements RegistryShutdownListener
{
...
    private ExecutorService executors;

    private void intitialise()
    {
...
    executors = Executors.newFixedThreadPool(3);

추신 : 나는 당신이 다른 Hivemind 서비스를 언급 할 수 없다는 것을 알고 있습니다. registryDidShutdown() 그러나 집행자들은 Hivemind 서비스 Afaik이 아니며, 그것은 그 일부입니다. java.util.concurrent

도움이 되었습니까?

해결책

찾은 후 이것 버그라는 것을 알 수 있습니다. 작업은 HiveModule의 구성 및 인터페이스 모두에 구현을 사용하는 대신 서비스에 인터페이스를 사용하는 것입니다 (때때로 건너 뛰는 것).
