同一个 Job Quartz.NET 的多个触发器 [英] Multiple triggers of same Job Quartz.NET

问题描述

我有以下代码:

 IScheduler scheduler = StdSchedulerFactory.GetDefaultScheduler();
            scheduler.Start();
            IJobDetail job = JobBuilder.Create<EmailJob>().StoreDurably().WithIdentity("J_Email", "J_Mailing").Build();         
            ITrigger trigger = TriggerBuilder.Create()
                                .WithIdentity("MailTrigger1", "T_Mail1")
                                .StartNow()                                
                                .WithSimpleSchedule(x => x.WithMisfireHandlingInstructionIgnoreMisfires()
                                    .WithIntervalInSeconds(3)
                                    .RepeatForever())
                                .Build();       


            ITrigger triggernew = TriggerBuilder.Create()
                               .WithIdentity("MailTrigger", "T_Mail")
                               .StartNow()                               
                               .WithSimpleSchedule(x => x.WithMisfireHandlingInstructionIgnoreMisfires()
                                   .WithIntervalInSeconds(5)
                                   .RepeatForever())
                               .Build();        
            scheduler.ScheduleJob(job,triggernew);
            scheduler.ScheduleJob(job,trigger);

我收到以下异常:

'Quartz.ObjectAlreadyExistsException' 类型的未处理异常发生在 Quartz.dll 中

An unhandled exception of type 'Quartz.ObjectAlreadyExistsException' occurred in Quartz.dll

附加信息:无法存储作业:'J_Mailing.J_Email'，因为已经存在具有此标识的人.

Additional information: Unable to store Job: 'J_Mailing.J_Email', because one already exists with this identification.

但有人告诉我，同一个 JOB 可以有多个触发器.也许我做错了什么?

But I have been told that you can have multiple triggers of the same JOB. Maybe I am doing something wrong?

推荐答案

将作业添加到调度程序.

Add the Job to the Scheduler.

然后在创建触发器时，使用 ForJob.

Then on the creation of the triggers, use ForJob.

下面的代码已经过测试.

The code below is tested.

IScheduler scheduler = StdSchedulerFactory.GetDefaultScheduler();


//// scheduler.DeleteJob(new JobKey("J_Email"));


IJobDetail job = JobBuilder.Create<MyConcreteJob>().StoreDurably().WithIdentity("J_Email", "J_Mailing").Build();

scheduler.AddJob(job, true /* bool replace */ ); /* Add the given IJob to the Scheduler - with no associated ITrigger.  */


ITrigger trigger = TriggerBuilder.Create()
                    .WithIdentity("MailTrigger1", "T_Mail1")
                    .StartNow()
                    .WithSimpleSchedule(x => x.WithMisfireHandlingInstructionIgnoreMisfires()
                        .WithIntervalInSeconds(3)
                        .RepeatForever())
                    .ForJob(job)
                    .Build();


ITrigger triggernew = TriggerBuilder.Create()
                   .WithIdentity("MailTrigger", "T_Mail")
                   .StartNow()
                   .WithSimpleSchedule(x => x.WithMisfireHandlingInstructionIgnoreMisfires()
                       .WithIntervalInSeconds(5)
                       .RepeatForever())
                   .ForJob(job)
                   .Build();


scheduler.ScheduleJob(triggernew);
scheduler.ScheduleJob(trigger);

scheduler.Start();
