Quartz .Net 无法工作......“批量获取 0 个触发器”

Question

我正在使用 Quartz 为 Windows 服务 .net core 创建作业调度程序。

我的代码完全遵循石英实现，如下面的链接所述。

https://www.quartz-scheduler.net/documentation/quartz-3.x/packages/aspnet-core-integration.html

https://andrewlock.net/using-quartz-net-with-asp-net-core-and-worker-services/

来自 Program.cs 的代码片段

  builder.Services.AddQuartz(q => {
  JobKey jobkey = new JobKey("QuartzDemoKey");

  q.UseMicrosoftDependencyInjectionJobFactory();
  q.AddJob < Worker > (config => config.WithIdentity(jobkey));
  q.AddTrigger(config => 
  config.WithIdentity("QuartzDemoTrigger").WithCronSchedule("0 
0/15 * * * ?").ForJob(jobkey));
});

直到昨天，我上面的代码都可以在本地和开发服务器上运行。现在它突然停止工作了。当我检查日志时，它给了我以下消息（不是错误）

我已经尝试了一切，但该作业不再触发，无论是在本地还是开发服务器中

我的工作（Worker.cs）代码片段如下：

public class Worker : IJob
{
    private readonly ScannerService _scannerService;
    private readonly ILogger<Worker> _logger;
    private readonly TimeSpan _interval = TimeSpan.FromDays(7);
    private readonly Dictionary<string, SanctionContext> _dbDictionary;
    private readonly IConfiguration _configuration;

    public Worker(
        ScannerService scannerService,
        ILogger<Worker> logger,
        Dictionary<string, SanctionContext> dbDictionary,
        IConfiguration configuration) =>
        (_scannerService, _logger, _dbDictionary, _configuration) = (scannerService, logger, dbDictionary, configuration);

 public Task Execute(IJobExecutionContext context)
    {
        Console.WriteLine("Quartz is running now");
        //_logger.LogInformation("Quartz running at: {time}", DateTimeOffset.Now);
        try
        {
            var counter = 0;

            _logger.LogWarning("Starting service");
            _logger.LogInformation("Worker running at: {time}", DateTimeOffset.Now);

            _scannerService.InitiateScanner(_dbDictionary, _logger, _configuration);
            //_scannerService.InitiateScanner(_dbDictionary);
            //_logger.LogWarning("{MDP}", "Msg success");

            _logger.LogInformation("Service ends at: {time} {runCounter}", DateTimeOffset.Now, counter);
            counter++;
            //await Task.Delay(_interval, stoppingToken);

        }
        //catch (TaskCanceledException)
        //{
        //    // When the stopping token is canceled, for example, a call made from services.msc,
        //    // we shouldn't exit with a non-zero exit code. In other words, this is expected...
        //}
        catch (Exception ex)
        {
            _logger.LogError(ex, "{Message}", ex.Message);

            // Terminates this process and returns an exit code to the operating system.
            // This is required to avoid the 'BackgroundServiceExceptionBehavior', which
            // performs one of two scenarios:
            // 1. When set to "Ignore": will do nothing at all, errors cause zombie services.
            // 2. When set to "StopHost": will cleanly stop the host, and log errors.
            //
            // In order for the Windows Service Management system to leverage configured
            // recovery options, we need to terminate the process with a non-zero exit code.
            //Environment.Exit(1);
        }

        return Task.CompletedTask;
    }

谢谢大家的支持，不过上述问题毕竟不是问题。当我们将 Cron 表达式设置为当天晚些时候的某个时间并且当我们进行调试时，它不会调用该函数，直到达到确切的日期和时间，这一事实让我分心。例如；如果当前是中午 12:21，并且我已将 Cron 设置为每天下午 6 点运行，直到下午 6 点，该作业将不会被执行（调用），并且它将始终在日志中给我一条消息像这样 - “批量获取 0 个触发器”，一旦到达下午 6 点，作业将被执行，现在它会显示“批量获取 1 个触发器”。我认为这是一个错误或错误，这是非常愚蠢的。我很抱歉浪费了任何人的时间。这是我第一次使用 Quartz，在这里发布问题之前我会更加小心。如果有人想将它用于 Quartz .Net Core Windows 服务实现，上面的设置对我来说效果很好（到目前为止，仍在测试）
