How can I configure Quartz in .net core to use dependency injection? I using standard .net core Dependency mechanism. In constructor of class that implements IJob, I need inject some dependencies.
You can use the Quartz.Spi.IJobFactory
interface and implement it. The Quartz documentations states:
When a trigger fires, the Job it is associated to is instantiated via the JobFactory configured on the Scheduler. The default JobFactory simply activates a new instance of the job class. You may want to create your own implementation of JobFactory to accomplish things such as having your application’s IoC or DI container produce/initialize the job instance. See the IJobFactory interface, and the associated Scheduler.SetJobFactory(fact) method.
ISchedulerFactory schedulerFactory = new StdSchedulerFactory(properties);
var scheduler = schedulerFactory.GetScheduler();
scheduler.JobFactory = jobFactory;
Edit
The implementation can look like this:
public class JobFactory : IJobFactory
{
protected readonly IServiceProvider Container;
public JobFactory(IServiceProvider container)
{
Container = container;
}
public IJob NewJob(TriggerFiredBundle bundle, IScheduler scheduler)
{
return Container.GetService(bundle.JobDetail.JobType) as IJob;
}
public void ReturnJob(IJob job)
{
// i couldn't find a way to release services with your preferred DI,
// its up to you to google such things
}
}
To use it with the Microsoft.Extensions.DependencyInjection
create your container like this:
var services = new ServiceCollection();
services.AddTransient<IAuthorizable, AuthorizeService>();
var container = services.BuildServiceProvider();
var jobFactory = new JobFactory(container);
