当前使用crystal.net运行12个作业。
前10个作业需要每30分钟运行一次。第二个作业需要每3分钟运行一次。
问题是每3分钟运行2个作业。该程序停止工作。它不会崩溃,控制台窗口仍在响应,但该应用程序不再触发作业。
我认为这是因为调度程序收集了垃圾。有人对此有解决方案吗?
StartAsync:
public async Task StartAsync(CancellationToken cancellationToken)
{
var scheduler = await GetScheduler();
await scheduler.Start();
await scheduler.ScheduleJob(GetAbsenceJob(), GetDefaultTrigger(nameof(AbsenceJob)));
await scheduler.ScheduleJob(GetAddressJob(), GetDefaultTrigger(nameof(AddressJob)));
await scheduler.ScheduleJob(GetCustomerJob(), GetDefaultTrigger(nameof(CustomerJob)));
await scheduler.ScheduleJob(GetDriverJob(), GetDefaultTrigger(nameof(DriverJob)));
await scheduler.ScheduleJob(GetPlanCombJob(), GetDefaultTrigger(nameof(PlanCombJob)));
await scheduler.ScheduleJob(GetPlanGroupJob(), GetDefaultTrigger(nameof(PlanGroupJob)));
await scheduler.ScheduleJob(GetSupplierJob(), GetDefaultTrigger(nameof(SupplierJob)));
await scheduler.ScheduleJob(GetTrailerJob(), GetDefaultTrigger(nameof(TrailerJob)));
await scheduler.ScheduleJob(GetTransportTypeJob(), GetDefaultTrigger(nameof(TransportTypeJob)));
await scheduler.ScheduleJob(GetVehicleJob(), GetDefaultTrigger(nameof(VehicleJob)));
await scheduler.ScheduleJob(GetImportFilesJob(), GetImportTrigger(nameof(ImportFilesJob)));
await scheduler.ScheduleJob(GetExtractFilesJob(), GetImportTrigger(nameof(ExtractFilesJob)));
}
GetSchedular
private static async Task<IScheduler> GetScheduler()
{
var props = new NameValueCollection {
{ "quartz.threadPool.threadCount", "20" },
{ "quartz.jobStore.misfireThreshold", "60000" },
{ "quartz.serializer.type", "binary" },
{ "quartz.scheduler.instanceName", "SynchroScheduler"},
{ "quartz.jobStore.type", "Quartz.Simpl.RAMJobStore, Quartz" },
{ "quartz.threadPool.type", "Quartz.Simpl.SimpleThreadPool, Quartz" }
};
var factory = new StdSchedulerFactory(props);
var scheduler = await factory.GetScheduler();
return scheduler;
}

如何启动服务:
var host = new HostBuilder()
.ConfigureHostConfiguration(configHost =>
{
configHost.SetBasePath(Directory.GetCurrentDirectory());
configHost.AddJsonFile(Text.Hostsettings, optional: true);
configHost.AddEnvironmentVariables(prefix: Text.Prefix);
configHost.AddCommandLine(args);
})
.ConfigureAppConfiguration((hostContext, configApp) =>
{
configApp.SetBasePath(Directory.GetCurrentDirectory());
configApp.AddJsonFile(Text.Appsettings, optional: true);
configApp.AddJsonFile($"appsettings.{hostContext.HostingEnvironment.EnvironmentName}.json", optional: true);
configApp.AddEnvironmentVariables(prefix: Text.Prefix);
configApp.AddCommandLine(args);
})
.ConfigureServices((hostContext, services) =>
{
services.AddLogging();
services.Configure<SynchroDbOptions>(hostContext.Configuration.GetSection("SynchoDbOptions"));
services.AddHostedService<DbSyncService>();
})
.ConfigureLogging((hostContext, configLogging) =>
{
configLogging.AddConfiguration(hostContext.Configuration.GetSection("Logging"));
configLogging.AddConsole();
})
.UseConsoleLifetime()
.Build();
host.RunAsync();
是的,你是对的。 ScheduleJob
仅注册该作业,它不等待其执行。在某个时候,垃圾收集器将出现并回收内存,而我记得有一个终结器可以对任何作业进行调度。因此,您需要存储要调度到的IScheduler
实例。
一种选择是将IScheduler
返回给调用者,以便他们可以决定如何存储它:
public async Task<IScheduler> StartAsync(CancellationToken cancellationToken)
{
...
...
return scheduler;
}
[另一种方法是让您的实例方法将其存储在成员变量中,并让类管理调度程序的生存期。如果不知道代码的全部范围,就无法说出哪一个最好。
