WFLYEJB0043：定時器[定時器]的上一次執行仍在進行中，在[時間]跳過此重疊的定時執行

我已經在單例EJB中定義了一些持久定時器，如下所示（使用WildFly 9.0.2 final）。WFLYEJB0043：定時器[定時器]的上一次執行仍在進行中，在[時間]跳過此重疊的定時執行

@Startup 
@Singleton 
@Lock(LockType.READ) 
public class BackgroundJobManager implements BackgroundJobService { 

    @Schedule(dayOfMonth = "1", month = "Jan", year = "*", hour = "0", minute = "0", second = "0", persistent = true) 
    private void doYearlyJob() { 
     //... 
    } 

    @Schedule(hour = "*", minute = "*/5", second = "0", persistent = true) 
    private void updateTopSellers() { 
     //... 
    } 

    @Schedule(hour = "*", minute = "*/1", second = "0", persistent = true) 
    private void updateFeedback() { 
     //... 
    } 

    //... 
}

在服務器啓動時以及應用程序重新部署時（如下僅爲其中的一部分）會發出幾個警告。

計時器服務在standalone-full-ha.xml中定義如下。

<timer-service thread-pool-name="default" default-data-store="clustered-store"> 
    <data-stores> 
     <database-data-store name="clustered-store" datasource-jndi-name="java:jboss/datasources/projectXADatasource" database="mysql" partition="timer"/> 
    </data-stores> 
</timer-service>

這些警告也出現，當這些計時器被保存到文件系統中的位置數據庫，無論應用程序是否部署在集羣（standalone-full-ha.xml）或非集羣（standalone-full.xml）環境。

我會定期清除standalone/data（除了部署的JDBC驅動程序和自定義內容），standalone/deployments和standalone/tmp的所有內容。定時器的症狀不再像以前那樣在standalone/data中提供，當定時器最初被保存到文件系統時。

是否有修復？

_{有一個question但我不滿意給出了答案（對不起）。此外，該問題使用JBoss EAP 6.4，以及爲什麼標記spring在應用程序服務器中使用EJB時對我而言是一個謎。}

更新：

的問題仍然是WildFly 10.0.0最終的穩定。

持續定時器和開發（hotdeploy/hotpublish）並不總是很好地結合在一起。從理論上講，IDE的服務器插件是怪罪。 – BalusC

NetBeans WildFly插件確實無法正常工作。談到另一個IDE是一個學習曲線，因爲我從一開始就習慣於使用NetBeans，所以不可能立即實現。我只想知道其他人如何以這種方式使用NetBeans的WildFly。 – Tiny

Eclipse也很不完美;） – BalusC

這是一個公認的錯誤。請參閱https://issues.jboss.org/browse/WFLY-6561。

的錯誤也被應用到JBoss 7以及：https://issues.jboss.org/browse/JBEAP-4442

感謝您的參考 – 99Sono

我們得到關於啓動這個「警告」，這似乎無論如何成功執行scheduledTimeout方法。這裏沒有錯誤，因爲@Schedule註釋中的persistent屬性默認爲true。此消息在服務器關閉一段時間後（在開發過程中）會顯示給我們（正在開發中）（因此，如果服務器未聯機，則會發生超時事件）。對這個問題的其他答案也可能是有效的，但是如果這個功能的適當功能被忽略，在這裏注意到這一點。

基本上，如果您認爲這是一個問題，請重新評估是否希望您的@Schedule定時事件重播在服務器脫機時錯過的所有事件。如果不是，則在批註中將persistent屬性設置爲false。
