从失火 Qualtz 中恢复的数据库错误

Question

我将 Quartz 配置为使用数据库中的计划作业。现在，当我启动调度程序时：

try {
  // Grab the Scheduler instance from the Factory
  Scheduler scheduler = StdSchedulerFactory.getDefaultScheduler();


  // and start it off
  scheduler.start();

  scheduler.shutdown();

} catch (Exception se) {
  Log.log(LogLevel.ERROR, se.getMessage());
}

项目的配置文件如下所示：

org.quartz.scheduler.instanceName = DatabaseScheduler
org.quartz.scheduler.skipUpdateCheck = true
org.quartz.threadPool.threadCount = 3

org.quartz.jobStore.class = org.quartz.impl.jdbcjobstore.JobStoreTX
org.quartz.jobStore.driverDelegateClass = org.quartz.impl.jdbcjobstore.MSSQLDelegate
org.quartz.dataSource.myDB.driver = com.microsoft.sqlserver.jdbc.SQLServerDriver
org.quartz.dataSource.myDB.URL = jdbc:sqlserver://server:1433;databaseName=schedules
org.quartz.dataSource.myDB.user = sa     
org.quartz.dataSource.myDB.password = password
org.quartz.dataSource.myDB.maxConnections = 2

org.quartz.jobStore.tablePrefix = QRTZ_
org.quartz.jobStore.dataSource = myDB
org.quartz.scheduler.misfirePolicy =  doNothing

我得到的错误是：

有人可以帮我解决这个错误吗？我还查看了 Whosebug 。没有任何运气。我正在使用 Quartz 2.2.3。即使我的数据库表是空的，我也会收到错误。

发现问题。在我的源代码中，调度程序启动并立即关闭调度程序。在这段时间里，什么都不能安排，而且在调用关闭之前调度程序的启动还没有完成。删除关闭调用它工作正常。
