运行 Net Core 控制台应用程序中的简单石英示例

Question

我正在尝试运行 .NET Core 控制台应用程序中的简单 Quartz 3.x 示例。我有这段代码（取自 here）：

public static async Task Main(string[] args)
{
    // 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();

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

    // Trigger the job to run now, and then every 40 seconds
    ITrigger trigger = TriggerBuilder.Create()
        .WithIdentity("myTrigger", "group1")
        .StartNow()
        .WithSimpleSchedule(x => x
            .WithIntervalInSeconds(40)
            .RepeatForever())
    .Build();

    await sched.ScheduleJob(job, trigger);
}

public class HelloJob : IJob
{
    public async Task Execute(IJobExecutionContext context)
    {
        await Console.Out.WriteLineAsync("HelloJob is executing.");
    }
}

随着对 3.x 的更改，一切都变得异步，它永远不会执行 HelloJob。只需运行s 即可结束并退出控制台应用程序。我在这里错过了什么吗？我们不能在核心控制台应用程序中运行像这样的 quartz 作业吗？

我可以运行 2.x 版本（没有异步方法）的常规控制台应用程序中的旧版本就好了：

public static void Main(string[] args)
{
    // construct a scheduler factory
    ISchedulerFactory schedFact = new StdSchedulerFactory();

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

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

    // Trigger the job to run now, and then every 40 seconds
    ITrigger trigger = TriggerBuilder.Create()
      .WithIdentity("myTrigger", "group1")
      .StartNow()
      .WithSimpleSchedule(x => x
          .WithIntervalInSeconds(40)
          .RepeatForever())
      .Build();

    sched.ScheduleJob(job, trigger);
}

public class HelloJob : IJob
{
    public void Execute(IJobExecutionContext context)
    {
        Console.WriteLine("HelloJob is executing.");
    }
}

Answer 1

我没有在控制台应用程序中使用 Quartz 2.x，但是版本 3.x 的行为有点符合预期：在安排 sched 之后应用程序继续执行并且退出。

可能这不是最优雅的解决方案，但最后的这两行应该有所帮助：

...
sched.ScheduleJob(job, trigger);
Console.ReadKey()
await sched.Shutdown();
