如何在ASP.NET中使用Quartz.net调度任务以触发邮件发送？

Question

我不知道如何在ASP.NET中使用Quartz.dll。我们应该在哪里编写代码以定时触发每天早上发送邮件的任务？

你有几个选项，具体取决于你想做什么和如何设置。例如，你可以将Quartz.Net服务器安装为独立的Windows服务，也可以将其嵌入到ASP.NET应用程序中。

如果你想嵌入运行它，那么你可以从全局.asax文件中启动服务器，就像这样（从源代码示例中的第12个示例）：

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();

如果您将其作为服务运行，您可以像这样远程连接它（例如＃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();

一旦你获得了对调度器的引用（通过远程访问或因为你有一个嵌入式实例），你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);

你能更新使用最新版本的帖子等内容吗？现在配置值的格式似乎已经改变了。谢谢！ - Snowy

我认为2.x版本的新方法是：

将此服务器导出到远程上下文

quartz.scheduler.exporter.type = Quartz.Simpl.RemotingSchedulerExporter, Quartz quartz.scheduler.exporter.port = 555 quartz.scheduler.exporter.bindName = QuartzScheduler quartz.scheduler.exporter.channelType = tcp quartz.scheduler.exporter.channelName = httpQuartz - NickG

啊，讨厌注释里不能换行！ - NickG

几周前，我写了一篇关于使用Quartz.Net在Windows Azure Worker Roles中调度作业的文章。自那以后，我遇到了一个要求，这促使我创建了一个包装器来包装Quartz.Net IScheduler。JobSchedule负责从CloudConfigurationManager读取计划字符串并安排作业。

CloudConfigurationManager从角色配置文件中读取设置，可以通过Windows Azure管理门户下的云服务配置部分进行编辑。

以下示例将安排一个需要每天在早上6点、8点、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Windows Azure Cloud Service项目，并在Role文件夹下找到所需的角色配置。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”，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根据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));

每日作业的实现如下。由于这只是一个演示，我不会添加任何特定的逻辑到作业中。

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

JobSchedule包装了Quartz.Net IScheduler。在之前的文章中，我谈到了包装第三方工具的重要性，这是一个很好的例子，因为我正在包含作业调度逻辑，并且我有可能在不影响使用JobSchedule的代码的情况下更改此逻辑。

应在角色启动时配置JobSchedule，并在整个角色生命周期内维护JobSchedule实例。可以通过在云服务的配置部分下更改“JobDailySchedule”设置来更改计划。然后，在云服务的实例部分下重新启动角色实例以应用新计划。

public class JobSchedule
{
    private readonly IScheduler sched;

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

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

    }

        schedule.Split(';')
