ASP.Net MVC 3、Ninject 和 Quartz.Net - 如何？

Question

我现在使用 Ninject 2.2.1.4 和我的 MVC3，我成功配置 Ninject 运行它，但我不知道如何让 Ninject 在我的 MVC3 中运行 Quartz.Net 有人可以帮忙吗？

Answer 1

创建一个使用 Ninject 的 JobFactory

public class NinjectJobFactory : IJobFactory
{
    private readonly Func<Type, IJob> jobFactory;

    public NinjectJobFactory (Func<Type, IJob> jobFactory)
    {
        this.jobFactory = jobFactory;
    }

    public IJob NewJob(TriggerFiredBundle bundle)
    {
        return this.jobFactory(bundle.JobDetail.JobType);
    }
}

还有一个 QuarzSchedulerProvider

public class QuartzSchedulerProvider : Provider<IScheduler> 
{
    private readonly IJobFactory jobFactory;
    private readonly IEnumerable<ISchedulerListener> listeners;
    private readonly ISchedulerFactory schedulerFactory;

    public QuartzSchedulerProvider(
        ISchedulerFactory schedulerFactory,
        IJobFactory jobFactory, 
        IEnumerable<ISchedulerListener> listeners)
    {
        this.jobFactory = jobFactory;
        this.listeners = listeners;
        this.schedulerFactory = schedulerFactory;
    }

    protected override IScheduler CreateInstance(IContext context)
    {
        var scheduler = this.schedulerFactory.GetScheduler();
        scheduler.JobFactory = this.jobFactory;
        foreach (var listener in this.listeners)
        {
            scheduler.AddSchedulerListener(listener);
        }

        return scheduler;
    }
}

还有一个 SchedulerFactoryProvider

public class QuartzSchedulerFactoryProvider : Provider<ISchedulerFactory>
{
    protected override ISchedulerFactory CreateInstance(IContext context)
    {
        var properties = new NameValueCollection();
        properties["quartz.dataSource.DataSource.connectionString"] = "Your connection string";
        properties["quartz.dataSource.DataSource.provider"] = "Your provider";

        properties["quartz.jobStore.type"] = "Quartz.Impl.AdoJobStore.JobStoreTX, Quartz";
        properties["quartz.jobStore.driverDelegateType"] = "Quartz.Impl.AdoJobStore.StdAdoDelegate, Quartz ";
        properties["quartz.jobStore.tablePrefix"] = "QRTZ_";
        properties["quartz.jobStore.dataSource"] = "DataSource";
        properties["quartz.jobStore.useProperties"] = "true";

        return new StdSchedulerFactory(properties);
    }
}

并配置

Bind<IJobFactory>().To<NinjectJobFactory>();
Bind<ISchedulerFactory>().ToProvider<QuartzSchedulerFactoryProvider>();
Bind<IScheduler>().ToProvider<QuartzSchedulerProvider>().InSingletonScope();
Bind<Func<Type, IJob>>().ToMethod(ctx => t => (IJob)ctx.Kernel.Get(t));

如果您需要一些 ISchedulerListener，例如用于记录也将它们绑定在这里。

在您想要添加作业的地方注入一个 IScheduler 实例，并且很可能您也必须将一个实例的属性注入到 global.asax 中。但请注意，我还没有在 MVC 上下文中使用过 Quarz，因为我认为计划任务不属于 Web 应用程序，而是属于在同一服务器上运行的服务。
