我有一个应用程序;它位于三个不同的服务器上,使用负载均衡器进行用户分配。
该应用程序使用自己的队列,我为作业添加了一个过滤器以保留其original
排队以防它们在某个时候失败。但话又说回来,它仍然表现得就像应用程序没有运行一样。错误如下;
System.InvalidOperationException: Recurring job can't be scheduled, see inner exception for details.
---> Hangfire.Common.JobLoadException: Could not load the job. See inner exception for the details.
---> System.IO.FileNotFoundException: Could not resolve assembly 'My.Api'.

What can be the issue here? The apps are running. And once I trigger the recurring jobs, they are good to go, until they show the above error.
这是我的 AppStart 文件;
private IEnumerable<IDisposable> GetHangfireServers()
{
Hangfire.GlobalConfiguration.Configuration
.SetDataCompatibilityLevel(CompatibilityLevel.Version_170)
.UseSimpleAssemblyNameTypeSerializer()
.UseRecommendedSerializerSettings()
.UseSqlServerStorage(HangfireServer, new SqlServerStorageOptions
{
CommandBatchMaxTimeout = TimeSpan.FromMinutes(5),
SlidingInvisibilityTimeout = TimeSpan.FromMinutes(5),
QueuePollInterval = TimeSpan.Zero,
UseRecommendedIsolationLevel = true,
DisableGlobalLocks = true
});
yield return new BackgroundJobServer(new BackgroundJobServerOptions {
Queues = new[] { "myapp" + GetEnvironmentName() },
ServerName = "MyApp" + ConfigurationHelper.GetAppSetting("Environment")
});
}
public void Configuration(IAppBuilder app)
{
var container = new Container();
container.Options.DefaultScopedLifestyle = new AsyncScopedLifestyle();
RegisterTaskDependencies(container);
container.RegisterWebApiControllers(System.Web.Http.GlobalConfiguration.Configuration);
container.Verify();
var configuration = new HttpConfiguration();
configuration.DependencyResolver = new SimpleInjectorWebApiDependencyResolver(container);
/* HANGFIRE CONFIGURATION */
if (Environment == "Production")
{
GlobalJobFilters.Filters.Add(new PreserveOriginalQueueAttribute());
Hangfire.GlobalConfiguration.Configuration.UseActivator(new SimpleInjectorJobActivator(container));
Hangfire.GlobalConfiguration.Configuration.UseLogProvider(new Api.HangfireArea.Helpers.CustomLogProvider(container.GetInstance<Core.Modules.LogModule>()));
app.UseHangfireAspNet(GetHangfireServers);
app.UseHangfireDashboard("/hangfire", new DashboardOptions
{
Authorization = new[] { new DashboardAuthorization() },
AppPath = GetBackToSiteURL(),
DisplayStorageConnectionString = false
});
AddOrUpdateJobs();
}
/* HANGFIRE CONFIGURATION */
app.UseWebApi(configuration);
WebApiConfig.Register(configuration);
}
public static void AddOrUpdateJobs()
{
var queueName = "myapp" + GetEnvironmentName();
RecurringJob.AddOrUpdate<HangfireArea.BackgroundJobs.AttachmentCreator>(
"MyApp_MyTask",
(service) => service.RunMyTask(),
"* * * * *", queue: queueName, timeZone: TimeZoneInfo.FindSystemTimeZoneById("Turkey Standard Time"));
}
这里可能有什么问题?
