我正在创建一个使用 Quartz.NET 的应用程序,该应用程序在 Windows 服务中使用。还有一个用 ASP.NET 编写的管理后端,管理员可以在其中添加作业并监视调度程序的状态。但是,我遇到了 ASP.NET 后端的问题。
连接是在 Global.asax 文件中建立的,起初它似乎工作 - 当用户登录到主仪表板时,它工作正常。问题是当用户点击另一个页面时,它会说调度程序“schedService”已经存在。
这是我的 Windows 服务代码:
NameValueCollection properties = new NameValueCollection();
properties["quartz.scheduler.instanceName"] = "schedService";
properties["quartz.threadPool.type"] = "Quartz.Simpl.SimpleThreadPool, Quartz";
properties["quartz.threadPool.threadCount"] = threadcount;
properties["quartz.threadPool.threadPriority"] = "Normal";
properties["quartz.jobStore.misfireThreshold"] = "60000";
properties["quartz.jobStore.type"] = "Quartz.Impl.AdoJobStore.JobStoreTX, Quartz";
properties["quartz.jobStore.useProperties"] = "false";
properties["quartz.jobStore.dataSource"] = "default";
properties["quartz.jobStore.tablePrefix"] = "QRTZ_";
//
properties["quartz.scheduler.exporter.type"] = "Quartz.Simpl.RemotingSchedulerExporter, Quartz";
properties["quartz.scheduler.exporter.port"] = "555";
properties["quartz.scheduler.exporter.bindName"] = "QuartzScheduler";
properties["quartz.scheduler.exporter.channelType"] = "tcp";
//
// if running MS SQL Server we need thisl
properties["quartz.jobStore.lockHandler.type"] = "Quartz.Impl.AdoJobStore.UpdateLockRowSemaphore, Quartz";
// config file
properties["quartz.dataSource.default.connectionString"] = connection;
properties["quartz.dataSource.default.provider"] = "SqlServer-20";
ISchedulerFactory schedService = new StdSchedulerFactory(properties);
IScheduler sched = schedService.GetScheduler();
ASP.NET Global.asax 代码:
public static IScheduler Sched()
{
NameValueCollection properties = new NameValueCollection();
properties["quartz.scheduler.instanceName"] = "schedMaintenanceService";
properties["quartz.scheduler.proxy"] = "true";
properties["quartz.scheduler.proxy.address"] = "tcp://localhost:555/QuartzScheduler";
ISchedulerFactory sf = new StdSchedulerFactory(properties);
IScheduler sched = sf.GetScheduler();
return sched;
}
然后我在每个 ASP.NET 页面中使用它:
public static IScheduler sched = Project.Global.Sched();
