C#帮助使用 quartz 实时配置间隔

Question

我需要根据数据库配置设置时间间隔。

例如，控制台应用程序以 10 秒的间隔运行，如果我将间隔更改为 20 秒，它将遵循新的间隔而不关闭控制台应用程序。

这是当前配置:

NameValueCollection properties = new NameValueCollection();
properties["quartz.threadPool.threadCount"] = "1";

ISchedulerFactory schedFact = new StdSchedulerFactory(properties);
IScheduler sched = schedFact.GetScheduler();

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


// Trigger the job to run now, and then every 30 seconds
ITrigger trigger = TriggerBuilder.Create()
    .WithIdentity("myTrigger", "group1")
    .StartNow()
    .WithSimpleSchedule(f => f.WithIntervalInSeconds(10)
                              .RepeatForever())
    .WithPriority(1)
    .Build();


// Tell quartz to schedule the job using our trigger
sched.ScheduleJob(job, trigger);

根据Quartz.NET manual ，您始终可以通过重新安排新触发器来更改现有触发器:

// retrieve the trigger
Trigger oldTrigger = sched.getTrigger(triggerKey("oldTrigger", "group1");

// obtain a builder that would produce the trigger
TriggerBuilder tb = oldTrigger.getTriggerBuilder();

// update the schedule associated with the builder, and build the new trigger
// (other builder methods could be called, to change the trigger in any desired way)
Trigger newTrigger = tb.withSchedule(simpleSchedule()
    .withIntervalInSeconds(10)
    .withRepeatCount(10)
    .build();

sched.rescheduleJob(oldTrigger.getKey(), newTrigger);
