CronJobs

CronJobs a powerful tool to automate ideas. 

 

Add a new cronjob

To add a new cronjob, create a new class that derives from ICronJob, IJob.

Example:

public class EventCleanUpJob : ICronJob, IJob
{
    public string Key { get; set; } = "EventCleanUp";
    public string Name { get; set; } = "Event Clean Up";
    public string CronExpression { get; set; } = "0 0/1 * * * ?";
    public bool IsEnabled { get; set; } = true;
    
    private ILogger<EventCleanUpJob> _logger;
    private EventAccess _eventAccess;

    public EventCleanUpJob(ILogger<EventCleanUpJob> logger, EventAccess eventAccess)
    {
        _logger = logger;
        _eventAccess = eventAccess;
    }

    public Task Execute(IJobExecutionContext context)
    {
        _logger.LogInformation($"Cron job executed at: {DateTime.Now}");

        _eventAccess.DeleteOutdated();
        
        return Task.CompletedTask;
    }
}

Add the CronJob to services:

services.AddSingleton<ICronJob, EventCleanUpJob>();

It's important that the Key is unique. It will be used for trigger manually. 

 

Run manually

To run a cronjob manually, the CronJob administration view is supporting this.
