Description

1. Use DI to resolve the Hangfire adapter, replacing Activator.CreateInstance.
2. Refactor variable naming for cron expressions in Hangfire background worker manager.

The reasons for the modification are as follows:

The TimeZone property in HangfirePeriodicBackgroundWorkerAdapter defaults to TimeZoneInfo.Utc, causing ExcelFileCleanupOptions.CronExpression = "0 23 * * *" to actually execute at 23:00 UTC (07:00 in China). There is a time zone discrepancy between the actual execution time of CronExpression and this.

After switching to dependency injection, CronExpression can execute based on the local timezone in the following way.

1. Create a new subclass of HangfirePeriodicBackgroundWorkerAdapter, such as MyAbpHangfirePeriodicBackgroundWorkerAdapter, and modify TimeZone to TimeZoneInfo.Local in the default constructor.

public class MyAbpHangfirePeriodicBackgroundWorkerAdapter<TWorker> : HangfirePeriodicBackgroundWorkerAdapter<TWorker>
    where TWorker : IBackgroundWorker
{
    public MyAbpHangfirePeriodicBackgroundWorkerAdapter()
    {
        TimeZone = TimeZoneInfo.Local;
    }
}

2. Replace the original HangfirePeriodicBackgroundWorkerAdapter

    public override void ConfigureServices(ServiceConfigurationContext context)
    {
        context.Services.AddSingleton(typeof(MyAbpHangfirePeriodicBackgroundWorkerAdapter<>));
        context.Services.Replace(ServiceDescriptor.Singleton(typeof(HangfirePeriodicBackgroundWorkerAdapter<>),
            typeof(MyAbpHangfirePeriodicBackgroundWorkerAdapter<>)));
    }
