Question

我正在使用最新的3.0.6版本的Quartz.net 我想安排一个每天运行的进程（当前示例是每40秒运行一次，但我会对其进行更改）我有调用该方法执行的方法，但是在“作业”类中启动该方法时，它似乎并未启动任何应启动的过程。我不确定为什么不触发？

 public static void Run()
    {

        var isRunning = false;
        IServiceCollection services = new ServiceCollection();
        Startup startup = new Startup();
        var serviceProvider = startup.ConfigureServices(services);
        IWindsorContainer _container = serviceProvider.GetService<IWindsorContainer>();
        while (true)
        {
            if (!isRunning)
            {
                isRunning = true;
                var configuration = _container.Resolve<IConfigurationRoot>();
                var _process = _container.Resolve<Process.Process>();
                int secondsForSleep = Convert.ToUInt16(configuration[Enums.SleepTime]);
                {
                    try
                    {
                        execute();
                    }
                    catch (Exception ex)
                    {
                    }
                    finally
                    {
                        isRunning = false;
                        Thread.Sleep(secondsForSleep);
                        _container.Release(_process);
                    }
                }
            }
        }
    }

    public static async void execute()
    {

        // construct a scheduler factory
        NameValueCollection props = new NameValueCollection
        {
            { "quartz.serializer.type", "binary" }
        };
        StdSchedulerFactory factory = new StdSchedulerFactory(props);

        // get a scheduler
        IScheduler sched = await factory.GetScheduler();
        await sched.Start();


        IJobDetail job = JobBuilder.Create<Job>()
            .WithIdentity("myJob", "group1")
            .Build();

        ITrigger trigger = TriggerBuilder.Create()
            .WithIdentity("myTrigger", "group1")
            .StartNow()
            .WithSimpleSchedule(x => x
                .WithIntervalInSeconds(1)
                .RepeatForever())
            .Build();

        await sched.ScheduleJob(job, trigger);

    }
}

public class Job : IJob
{
    public async Task Execute(IJobExecutionContext context)
    {
        JobKey key = context.JobDetail.Key;
        IServiceCollection services = new ServiceCollection();
        Startup startup = new Startup();
        var serviceProvider = startup.ConfigureServices(services);
        IWindsorContainer _container = serviceProvider.GetService<IWindsorContainer>();
        var configuration = _container.Resolve<IConfigurationRoot>();
        var _process = _container.Resolve<Process.Process>();
        Task t = new Task(() =>
        {
             _process.MainProcess();
        });
       t.Start();
        await t;
    }
}

我是否错误地设置了IJobDetail对象或其他东西？有人有类似的问题吗？看来我确实按照文档做了eryerything，但仍然无法正常工作

这不是您问题的直接答案，但是如果问题与以下相关，则可能会对您有所帮助。

看，您已经将execute方法定义为async void。结果，您无法通过await execute()调用它，所以

您的try-catch块将不处理execute方法中引发的任何异常
finally块在调用execute()方法后立即运行（不等待方法完成）

换句话说，将您的代码更改为async Task execute()和await execute()并再次进行测试。
