asp.net - 如何在 ASP.NET 中使用 Quartz.net

Question

我不知道如何在 ASP.NET 中使用 Quartz.dll。在哪里编写调度作业以每天早上触发邮件的代码？请如果有人知道它请帮助我...

您有几个选项，具体取决于您想要做什么以及如何设置它。例如，您可以将 Quartz.Net 服务器安装为独立的 Windows 服务，也可以将其嵌入到您的 asp.net 应用程序中。

如果你想嵌入运行它，那么你可以从你的 global.asax 启动服务器，就像这样（来自源代码示例，示例 #12）：

NameValueCollection properties = new NameValueCollection();
properties["quartz.scheduler.instanceName"] = "RemoteServer";

// set thread pool info
properties["quartz.threadPool.type"] = "Quartz.Simpl.SimpleThreadPool, Quartz";
properties["quartz.threadPool.threadCount"] = "5";
properties["quartz.threadPool.threadPriority"] = "Normal";

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

如果您将它作为服务运行，您将像这样远程连接到它（来自示例 #12）：

NameValueCollection properties = new NameValueCollection();
properties["quartz.scheduler.instanceName"] = "RemoteClient";

// set thread pool info
properties["quartz.threadPool.type"] = "Quartz.Simpl.SimpleThreadPool, Quartz";
properties["quartz.threadPool.threadCount"] = "5";
properties["quartz.threadPool.threadPriority"] = "Normal";

// set remoting expoter
properties["quartz.scheduler.proxy"] = "true";
properties["quartz.scheduler.proxy.address"] = "tcp://localhost:555/QuartzScheduler";
// First we must get a reference to a scheduler
ISchedulerFactory sf = new StdSchedulerFactory(properties);
IScheduler sched = sf.GetScheduler();

一旦你引用了调度程序（无论是通过远程处理还是因为你有一个嵌入式实例），你就可以像这样安排作业：

// define the job and ask it to run
JobDetail job = new JobDetail("remotelyAddedJob", "default", typeof(SimpleJob));
JobDataMap map = new JobDataMap();
map.Put("msg", "Your remotely added job has executed!");
job.JobDataMap = map;
CronTrigger trigger = new CronTrigger("remotelyAddedTrigger", "default", "remotelyAddedJob", "default", DateTime.UtcNow, null, "/5 * * ? * *");
// schedule the job
sched.ScheduleJob(job, trigger);

几周前，我写了一篇关于使用 Quartz.Net 在 Windows Azure Worker Roles 中安排作业的文章。从那时起，我遇到了一个要求，促使我围绕 Quartz.Net IScheduler 创建一个包装器。JobSchedule 负责从 CloudConfigurationManager 读取调度字符串并调度作业。

CloudConfigurationManager 从角色的配置文件中读取设置，可以通过云服务配置部分下的 Windows Azure 管理门户进行编辑。

以下示例将安排需要在每天早上 6 点、上午 8 点、上午 10 点、下午 12:30 和下午 4:30 执行的作业。计划在角色设置中定义，可以通过 Visual Studio 进行编辑。要访问角色设置，请转到您的 Windows Azure 云服务项目并在角色文件夹下找到所需的角色配置。通过双击配置文件打开配置编辑器，然后导航到“设置”选项卡。单击“添加设置”并将新设置命名为“JobDailySchedule”并将其值设置为 6:0;8:0;10:0;12:30;16:30;

The code from this Post is part of the Brisebois.WindowsAzure NuGet Package

To install Brisebois.WindowsAzure, run the following command in the Package Manager Console

PM> Install-Package Brisebois.WindowsAzure

Get more details about the Nuget Package.

然后使用 JobSchedule 使用角色配置文件中定义的计划安排每日作业。

var schedule = new JobSchedule();

schedule.ScheduleDailyJob("JobDailySchedule",
                            typeof(DailyJob));

DailyJob 实现如下。由于这是一个演示，我不会在作业中添加任何特定的逻辑。

public class DailyJob : IJob
{
    public void Execute(IJobExecutionContext context)
    {
        //Do your daily work here
    }
}

JobSchedule 包装了 Quartz.Net IScheduler。在之前的一篇文章中，我谈到了包装你的 3rd 方工具的重要性，这是一个很好的例子，因为我包含作业调度逻辑，我可以在不影响使用 JobSchedule 的代码的情况下更改此逻辑。

JobSchedule 应该在 Role 启动时配置，并且 JobSchedule 实例应该在 Role 的整个生命周期中保持。可以通过在云服务的配置部分下的 Windows Azure 管理门户更改“JobDailySchedule”设置来更改计划。然后要应用新计划，请通过云服务实例部分下的 Windows Azure 管理门户重新启动角色实例。

public class JobSchedule
{
    private readonly IScheduler sched;

    public JobSchedule()
    {
        var schedFact = new StdSchedulerFactory();

        sched = schedFact.GetScheduler();
        sched.Start();
    }

    }
