Question

我写了一个JobListener来跟踪WPF应用启动的Quartz作业。

该应用会创建一个作业列表，调用BackgroundWorker来调度所有作业，并为每个作业注册JobListener。 JobListener旨在更新将在应用用户界面中动态显示的不同列表。

正确安排和执行作业，但由于某些未知原因，JobListener事件永远不会被触发。

JobListener：

class DummyJobListener : IJobListener
{
    private ObservableCollection<JobKey> _pendingJobs;
    private ObservableCollection<JobKey> _runningJobs;
    private ObservableCollection<JobKey> _finishedJobs;

    public readonly Guid Id = Guid.NewGuid();

    public StressJobListener(ObservableCollection<JobKey> pendingJobs, ObservableCollection<JobKey> runningJobs, ObservableCollection<JobKey> finishedJobs)
    {
        _pendingJobs = pendingJobs;
        _runningJobs = runningJobs;
        _finishedJobs = finishedJobs;
    }

    public void JobToBeExecuted(IJobExecutionContext context)
    {
        JobKey jobKey = context.JobDetail.Key;
        _pendingJobs.Remove(jobKey);
        _runningJobs.Add(jobKey);
    }

    public void JobWasExecuted(IJobExecutionContext context, JobExecutionException jobException)
    {
        JobKey jobKey = context.JobDetail.Key;
        _runningJobs.Remove(jobKey);
        _finishedJobs.Add(jobKey);
    }

    public void JobExecutionVetoed(IJobExecutionContext context)
    {
    }

    public string Name
    {
        get { return "DummyJobListener" + Id; }
    }
}

App：

private BackgroundWorker _runJobs = new BackgroundWorker();

ObservableCollection<IJobDetail> jobList = new ObservableCollection<IJobDetail>();

ObservableCollection<JobKey> _pendingJobs = new ObservableCollection<JobKey>();
ObservableCollection<JobKey> _runningJobs = new ObservableCollection<JobKey>();
ObservableCollection<JobKey> _finishedJobs = new ObservableCollection<JobKey>();

public MainWindow()
{
    InitializeComponent();

    // fill jobList with jobs

    _runJobs.DoWork += RunJobs;
}


private void btnStart_Click(object sender, RoutedEventArgs e)
{
    _runJobs.RunWorkerAsync();
}

private void RunJobs(object sender, DoWorkEventArgs e)
{
    IScheduler scheduler = // GetScheduler

    foreach (IJobDetail x in jobList)
    {
        scheduler.ListenerManager.AddJobListener(new DummyJobListener(_pendingJobs, _runningJobs, _finishedJobs), KeyMatcher<JobKey>.KeyEquals(x.Key));
        scheduler.ScheduleJob(x, someTrigger);
        _pendingJobs.Add(x.Key);
    }

    scheduler.Start();

}

我在这里错过了什么吗？

Answer 1

我明白了。

我错过了配置中的quartz.threadPool.type密钥，该密钥是在Quartz.Simpl.ZeroSizeThreadPool, Quartz上设置的（此Quartz配置主要用于Web环境）。当您的调度程序只想安排作业而不运行它们时，将使用此设置，将此任务留给作为服务运行的Quartz Server。 “使用非启动调度程序执行的作业”部分应该引导我朝这个方向发展。

将此密钥更改为Quartz.Simpl.SimpleThreadPool, Quartz解决了问题。

Answer 2

您是否正在运行 scheduler.Start（）？我认为默认情况下会禁用调度程序，您需要明确启动它。

未触发Quartz.Net JobListener事件
