Question

如果满足某些条件，如何停止工作？

下面是一个示例，该示例每5秒运行一次作业并生成1到100之间的随机数。现在我想让生成的数字为50时停止工作。

class Program
{
    static void Main(string[] args)
    {
        JobScheduler jobScheduler = new JobScheduler();
        jobScheduler.Start();
        Console.ReadLine();
    }
}

public class JobScheduler
{
    public async void Start()
    {
        ISchedulerFactory schedulerFactory = new StdSchedulerFactory();
        IScheduler scheduler = await schedulerFactory.GetScheduler();
        await scheduler.Start();


        string id_job1 = Guid.NewGuid().ToString();

        // define the job and tie it to our HelloJob class
        IJobDetail job1 = JobBuilder.Create<HelloJob>()
            .WithIdentity(Guid.NewGuid().ToString(), "group1")
            .Build();

        // Trigger the job to run now, and then every 5 seconds
        ITrigger trigger1 = TriggerBuilder.Create()
            .WithIdentity(id_job1, "group1")
            .StartNow()
            .WithSimpleSchedule(x => x
                .WithIntervalInSeconds(5)
                .RepeatForever())
        .Build();                       


        var listener = new CountJobListener();
        scheduler.ListenerManager.AddJobListener(listener, KeyMatcher<JobKey>.KeyEquals(job1.Key));

        await scheduler.ScheduleJob(job1, trigger1);          

    }
}

public class HelloJob : IJob
{
    SomethingToDo obj = new SomethingToDo();
    public async Task Execute(IJobExecutionContext context)
    {           
        await Console.Out.WriteLineAsync("HelloJob is executing.");
        int num = obj.CreateRandomNumbers();
        Console.WriteLine(num);
    }
}

public class CountJobListener : IJobListener
{       

    public async Task JobToBeExecuted(IJobExecutionContext context, CancellationToken cancellationToken = default(CancellationToken))
    {

    }

    public async Task JobExecutionVetoed(IJobExecutionContext context, CancellationToken cancellationToken = default(CancellationToken))
    {

    }

    public async Task JobWasExecuted(IJobExecutionContext context, JobExecutionException jobException, CancellationToken cancellationToken = default(CancellationToken))
    {

    }

    public string Name { get { return "CountJobListener"; } }

}

public class SomethingToDo
{
    public int CreateRandomNumbers()
    {
        return new Random().Next(1, 101);
    }
}

如何实现？

            static void Main(string[] args)
            {
                JobScheduler jobScheduler = new JobScheduler();
                jobScheduler.Start();
                Console.ReadLine();
            }
        }

                IScheduler scheduler = await schedulerFactory.GetScheduler();
                await scheduler.Start();


                string id_job1 = Guid.NewGuid().ToString();

                // define the job and tie it to our HelloJob class
                IJobDetail job1 = JobBuilder.Create<HelloJob>()
                    .WithIdentity(Guid.NewGuid().ToString(), "group1")
                    .Build();

                // Trigger the job to run now, and then every 5 seconds
                ITrigger trigger1 = TriggerBuilder.Create()
                    .WithIdentity(id_job1, "group1")

                await Console.Out.WriteLineAsync("Job is executing.");
                int num = obj.CreateRandomNumbers();
                context.JobDetail.JobDataMap["GeneratedNumber"] = num;  // Store some value in JobMap to be available for further processing if necessary
                Console.WriteLine(num);

                if (num == 5)
                    await context.Scheduler.PauseJob(context.JobDetail.Key);

            }
        }

        public class CountJobListener : IJobListener
        {

您可以像这样暂停作业

jobScheduler.PauseJob(new JobKey(<JobKey>, <Group>));

成功完成后停止Quartz作业
