通用 Quartz 作业应用于不同的类和时间表

Question

我在 Net Core 6 项目中有以下 Quartz 作业：

public class StrategyJob : IJob {

  private readonly Logger _logger;

  private readonly Strategy _strategy;

  public StrategyJob(Logger logger, Strategy strategy) {

    _logger = logger;
    _strategy = strategy;

  }
  
  public async Task Execute(IJobExecutionContext context) {

    Result result = await strategy.Run();

    if (result.Code == ResultCode.Error)
      _logger.Error(result.ErrorMessage);

  } 

}

Quartz 配置如下：

services.AddQuartz(x => {

  // Quartz configuration

  x.AddJob<StrategyJob>(y => y
    .WithIdentity("StrategyJob")
  );

  x.AddTrigger(y => y
    .WithIdentity("Minute10OfEveryHour")  
    .ForJob("StrategyJob")
    .WithSimpleSchedule(x => x.WithIntervalInSeconds(10).RepeatForever())
  );

});

我需要使 StrategyJob 通用并将其应用于不同的策略/计划：

Strategy fs = new FastStrategy(2, 4, 5); > Run it every second

Strategy ss = new SlowStrategy("xy", 2); > Run it every day

... More strategies, each with a schedule, but the job execution will be the same.

如何创建通用 StrategyJob 并将其应用于不同的策略/计划？

Answer 1

您可以将策略添加到触发器的数据中。只要您不将调度程序保存在数据库中，就不必担心触发器数据的序列化。

var jobData = new Dictionary<string, object>
{
    { "Strategy", new FastStrategy(...) }
}

x.AddTrigger(y => y
   .UsingJobData(new JobDataMap(jobData))
   . ...

您需要提供自己的 IJobFactory

实现

public class JobFactory : IJobFactory
{
    public IJob NewJob(TriggerFiredBundle bundle, IScheduler scheduler)
    {
        var strategy = (Strategy)bundle.JobDetail.JobDataMap.Get("Strategy");
        return new StrategyJob(logger, strategy);
    }
}
