The core component of my heart (pluggable AOP) ~ scheduling component

Recommended for you: Get network issues from WhatsUp Gold. Not end users.

Back to the directory is a scheduling component, it can flexibly set your debugging mode, by time, by date, by the cycle can be easily achieved, quartz can be used not only in web, but also can be deployed in WinForm, winservice, let's make a simple debugging services, we taking WEB as an example, the WEB end of the popular MVC3 implementation.

We need to introduce the three components of DLL


For WEB projects, scheduling after injection we can put it in the global.asax, it can make our scheduling task start automatically when the application starts, automatically at the end of the application, this is the end, we need to see.

Global.asax content:

 IScheduler sched;
        protected void Application_Start()

            // By default on Entity Framework using LocalDB
            Database.DefaultConnectionFactory = new SqlConnectionFactory(@"Data Source=(localdb)\v11.0; Integrated Security=True; MultipleActiveResultSets=True");


            string cronExpr = ConfigurationManager.AppSettings["cronExpr"];
            ISchedulerFactory sf = new Quartz.Impl.StdSchedulerFactory();
            sched = sf.GetScheduler();
            IJobDetail job = JobBuilder.Create<Callback>()
                .WithIdentity("job1", "group1")

            ICronTrigger trigger = (ICronTrigger)TriggerBuilder.Create()
                .WithIdentity("trigger1", "group1")

            sched.ScheduleJob(job, trigger);

        protected void Application_End(object sender, EventArgs e)
            //   Applications running in the closure of the code
            if (sched != null)

Look at our scheduling code, the callback method that debugging, it must implement the IJob interface, this interface has a method of Execute, we put the thing to do here, and it has a parameter IJobExecutionContext, which passed is the current task (job) object.

   public class Callback : IJob
        private readonly ILog logger = LogManager.GetLogger(typeof(Callback));

        #region IJob members

        public void Execute(IJobExecutionContext context)
            logger.Info(context.JobDetail.Key.Name + DateTime.Now);


Below we look at the relevant information in the configuration file, which is composed of quartz nodes and log4 log configuration node.

Well, now we can run WEB programs, then the root directory of your log directory should have our scheduling log, ha ha.
