问题 I use quartz in my asp website, i initialize the scheduler in application_start method and shutdown in application_end method ,my trigger will fire everyday but I found that my scheduler will automatically shutdown if there are not request for a while ,so my background works will not triggered,are there any better way to keep the scheduler life long and only shutdown when the server stopped? 回答1: For better knowledge sharing: There are two suggestions: http://www.codeproject.com/Articles

问题 Is there any way to gain access to the HttpContext object from a Quartz.NET job? HttpContext.Current and the likes do not seem to work with Quartz.NET jobs. 回答1: Yes there is a way. Just set HttpContext.Current to JobDataMap when instantiating new scheduler(probably in Application_Start event in Global.asax) like this: jobDetail.JobDataMap["context"] = HttpContext.Current; Then access it in Execute method like this: HttpContext context = context.JobDetail.JobDataMap["context"] as HttpContext;

问题 I am into shared hosting and they do not allow me to use windows scheduler... So what are the ways of achieving scheduled tasks ie(timed mail) in asp.net... I just saw background process by Jeff Atwood blog... Is it relaible? Or any other ways of doing scheduled tasks... Then i found quartz.net but i can't find a simple example that embeds quartz.net into an asp.net( without installing a Quartz.Net server as a standalone windows service )... Any suggestion on quartz.net... 回答1: I was

问题 I'm working in C# using Quartz.NET and am having problems setting the misfire instruction on a CronTrigger. I'm running an SQL backend with the Quartz DB installed. I have the following code which works fine for creating a job and running a scheduler. IScheduler _scheduler; IJobDetail job; ISchedulerFactory sFactory; ICronTrigger trig; sFactory = new StdSchedulerFactory(); _scheduler = sFactory.GetScheduler(); _scheduler.Start(); job = JobBuilder.Create<Test>().WithIdentity("testJob",

问题 We are starting a new project in .NET Core 2, I will be needing some approach to run a scheduled job that will do some work. This app will be hosted in Linux server or AWS linux instance. I have done this with Azure WebJobs and .NET 4.6. How is this done with .Net Core and Linux 回答1: I dont know who upvoted this question. I went out and used Hangfire Jobs. Pretty easy to work. not actually a scheduled job. But we can start it with a Run() and be on our way doing other things. No need to wait

问题 I am a beginner in Quartz.Net. How can I add multiple jobs in a scheduler? For the sake of learning I am using Console Application. 回答1: If you're new to Quartz.Net I would suggest you to start with Jay Vilalta's Blog and the old one where you can find loads of tutorials and useful infos about Quartz.Net. If you want to schedule multiple jobs in your console application you can simply call Scheduler.ScheduleJob ( IScheduler ) passing the job and the trigger you've previously created:

问题 I've been trying to figure out how to call the ScheduleJobs methods within Quartz.Net, but struggling to create the correct parameters it's expecting. Here's what I've tried: IJobDetail jobDetail = JobBuilder.Create<ReportJob>() .WithIdentity("theJob") .Build(); ITrigger everydayTrigger = TriggerBuilder.Create() .WithIdentity("everydayTrigger") // fires .WithCronSchedule("0 0 12 1/1 * ?") // start immediately .StartAt(DateBuilder.DateOf(DateTime.Now.Hour, DateTime.Now.Minute, DateTime.Now

问题 I'm currently writing a web application that provides some database manipulation. The system also needs to be capable working with different databases.The problem is that certain fields in the database have to be updated with data from a RESTful api. To perform these updates, I use a Quartz.NET schedule that makes a job for every table that needs to be updated.This job checks if it needs to update the relevant database. If it does, it gets the information from the REST-service. When I don't

问题 Is there any way to create a new trigger on a JobDetail record which is in the database, but not in memory? Specific use: I have jobs scheduled to run daily using a cron trigger. Sometimes a particular day's job needs to be re-run with the same parameters. I'd like to create a new simple trigger using the same JobDetail, since that's where the parameters are stored. Reschedule() doesn't work, since it deletes the existing trigger. Is that possible? 回答1: In Quartz.net, I had to do this a

问题 ...when a job is still being executed when its next execution time occurs? For example, if I have a job that occurs every 30 seconds, and after the 30 seconds it is still operating, would the next instance come into play or would it wait? 回答1: The short answer is that a new job will be executed, unless you are inheriting from IStatefulJob, in which case only one job instance is allowed to run at a time. 回答2: As TskTsk answered, you can implement IStatefulJob insted of IJob but there is a
