本文介绍了WFLYEJB0043：先前执行的计时器[计时器]仍在进行中，在[时间]跳过此重叠的计划执行的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我在单例EJB中定义了一些持久性计时器，如下所示（使用WildFly 9.0.2 final）。

I have defined some persistent timers in a singleton EJB as follows (using WildFly 9.0.2 final).

@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() {
        //...
    }

    //...
}

在服务器启动时以及重新部署应用程序时会发出几个警告（如下所示）（

Several warnings are issued on server startup and when the application is redeployed like the following (these are merely a few of them).

定时服务在<$中定义c $ c> standalone-full-ha.xml 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>

当这些定时器持久存储到文件系统而不是数据库时，也会出现这些警告无论应用程序是部署在集群中（ standalone-full-ha.xml ）还是非集群（ standalone-full.xml ）environment。

These warnings also appear, when these timers are persisted to the file system in place of a database, no matter whether the application is deployed in a cluster (standalone-full-ha.xml) or non-cluster (standalone-full.xml) environment.

我经常清除 standalone / data 的所有内容（已部署的JDBC除外）驱动程序和自定义内容），独立/部署和 standalone / tmp 在必要时。定时器的症状在独立/数据中不再可用，因为它们之前是最初被定时器保存到文件系统的时间。

I regularly flush out all contents of standalone/data (except the deployed JDBC driver and custom contents), standalone/deployments and standalone/tmp whenever necessary. Symptoms of timers are no longer available in standalone/data as they were before, when timers were initially being persisted to the file system.

有没有修复？

有一个问题但我对给出的答案不满意（抱歉）。此外，该问题使用JBoss EAP 6.4以及为什么标签 spring 在应用程序服务器中使用EJB时​​在那里呈现对我来说是一个谜。

There is a question but I am not satisfied with the answer given (sorry). Besides, that question uses JBoss EAP 6.4 and why the tag spring presents there while using EJBs in an application server is a mystery to me.

更新：

该问题在WildFly 10.0.0决赛中保持不变。

The issue remains stationary in WildFly 10.0.0 final.

推荐答案

这是一个公认的错误。请参见 https://issues.jboss.org/browse/WFLY-6561 。

This is an acknowledged bug. See https://issues.jboss.org/browse/WFLY-6561.

该错误也适用于JBoss 7： https://issues.jboss.org/browse/JBEAP-4442

The bug has also been applied to JBoss 7 as well: https://issues.jboss.org/browse/JBEAP-4442
