"Turn" quartz.net open source Job scheduling framework use detailed

The Quartz.net job scheduling framework is a. NET extended ported version of the Quartz Scheduler project developed by the great organization Opensymphony. Supports cron-like expressions, clusters, databases. Features are powerful, let alone.

Now let's break down a little project I've done recently on scheduling, to help understand the quartz.net and common methods.

Simple usage of quartz.net-Getting Started

If you are a novice to quartz.net, console starter Here, it is recommended to follow the next, then 10 minutes to understand quartz.net is so easy to do.

1. Create a scheduled schedule that executes every 3 seconds

public class Runmain {static void Main (string[] args) {Console.WriteLine (DateTime.Now.ToStri            Ng ("R"));            1. First create a job scheduling pool ischedulerfactory Schedf = new Stdschedulerfactory (); IScheduler sched = Schedf.            Getscheduler (); 2. Create a specific job ijobdetail job = jobbuilder.create<jobdemo> ().                       Build (); 3. Create and configure a trigger Isimpletrigger trigger = (Isimpletrigger) triggerbuilder.create (). Withsimpleschedule (X=>x.withintervalinseconds (3). Withrepeatcount (int. MaxValue)).            Build (); 4. Join the sched in the job scheduling pool.            Schedulejob (Job, trigger); 5. Start running sched.            Start ();        Console.readkey (); }} public class Jobdemo:ijob {//<summary>///This is the job schedule per time execution method///&LT;/SUMMARY&G        T            <param name= "context" ></param> public void Execute (Ijobexecutioncontext context) { Console.writEline (DateTime.Now.ToString ("R")); }    }

Note:1, note the order in which the job schedule was created. 2, the above code execution result is, every three seconds executes once jobdemo in the Execute, if the program does not stop, the endless execution to the everlasting, hehe, tore the egg.

2. Improved (Rich scheduling): The last job, I want him to execute every three seconds, a total of 100 times, start execution time set at the current time, the end time I set in 2 hours, but 100 times executed no more than 2 small time is no longer executed.

    public class Runmain {static void Main (string[] args) {Console.WriteLine (DateTime.Now.To            String ("R"));            First create a job scheduling pool ischedulerfactory Schedf = new Stdschedulerfactory (); IScheduler sched = Schedf.            Getscheduler (); Create a specific job ijobdetail job = jobbuilder.create<jobdemo> ().            Build ();            Nextgivenseconddate: If the first parameter is null, the table name is delayed by 2 seconds later in the current time.            DateTimeOffset startTime = Datebuilder.nextgivenseconddate (DateTime.Now.AddSeconds (1), 2);            DateTimeOffset endTime = Datebuilder.nextgivenseconddate (DateTime.Now.AddHours (2), 3); Create and configure a trigger Isimpletrigger trigger = (Isimpletrigger) triggerbuilder.create (). StartAt (StartTime). EndAt (EndTime). Withsimpleschedule (X=>x.withintervalinseconds (3). Withrepeatcount (100)).            Build (); Join the sched in the job scheduling pool. ScheduleJob (job, trigger); Start Running sched.            Start ();        Console.readkey (); }} public class Jobdemo:ijob {//<summary>///This is the job schedule per time execution method///&LT;/SUMMARY&G        T            <param name= "context" ></param> public void Execute (Ijobexecutioncontext context) {        Console.WriteLine (DateTime.Now.ToString ("R")); }    }

3. Continue to improve (Cron-like use): The first two job scheduling is too simple, if I want to 10,20,25,26,33,54 minutes per hour, every minute of the 1th, 10, 14 seconds to execute once. So the above is obviously not enough. This is when I introduce the cron-like expression in order to achieve a variety of time-latitude calls.

 public class Runmain {static void Main (string[] args) {Console.WriteLine (DateTime.Now.ToStr            ING ("R"));            First create a job scheduling pool ischedulerfactory Schedf = new Stdschedulerfactory (); IScheduler sched = Schedf.            Getscheduler (); Create a specific job ijobdetail job = jobbuilder.create<jobdemo> ().            Build ();            Nextgivenseconddate: If the first parameter is null, the table name is delayed by 2 seconds later in the current time.            DateTimeOffset startTime = Datebuilder.nextgivenseconddate (DateTime.Now.AddSeconds (1), 2);            DateTimeOffset endTime = Datebuilder.nextgivenseconddate (DateTime.Now.AddYears (2), 3); Create and configure a trigger Icrontrigger trigger = (Icrontrigger) triggerbuilder.create (). StartAt (StartTime). EndAt (EndTime).                                        Withcronschedule ("1,10,14 10,20,25,26,33,54 * * *?") .            Build (); Join the sched in the job scheduling pool.            Schedulejob (Job, trigger);      Start running      Sched.            Start ();            Hangs 2 days Thread.Sleep (Timespan.fromdays (2)); After 2 days, the job schedule is closed and sched is not executed.            Shutdown ();        Console.readkey (); }} public class Jobdemo:ijob {//<summary>///This is the job schedule per time execution method///&LT;/SUMMARY&G        T            <param name= "context" ></param> public void Execute (Ijobexecutioncontext context) {        Console.WriteLine (DateTime.Now.ToString ("R")); }    }

A detailed description of job scheduling project based on Quartz.net

The final effect is shown in the first diagram that begins.

The following is mainly said, job scheduling in how to locate the specific job scheduling, and to the job scheduling group, name, add, start, stop.

First show the following table structure, in the project I call job scheduling for task scheduling.

1, new job scheduling.

 <summary>///Task Scheduler///</summary> public static IScheduler scheduler = NULL; public static IScheduler Getscheduler () {if (scheduler! = NULL) {return SCH            Eduler;                } else {ischedulerfactory SCHEDF = new Stdschedulerfactory (); IScheduler sched = Schedf.                Getscheduler ();            Return sched;        }}///<summary>//Add Task Schedule///</summary>//<returns></returns>                public bool Addschedulejob (wj_scheduleentity m) {try {if (M! = null) {if (m.starruntime = = null) {M.starruntime = D                    Atetime.now;                    } DateTimeOffset starruntime = Datebuilder.nextgivenseconddate (m.starruntime, 1); if (M.endruntime = = nulL) {m.endruntime = DateTime.MaxValue.AddDays (-1);                    } DateTimeOffset endruntime = Datebuilder.nextgivenseconddate (m.endruntime, 1);                    Scheduler = Getscheduler (); Ijobdetail job = jobbuilder.create
Note:1. Here are the functions that the job schedule executes. 2. The above withidentity (M.jobname, M.jobgroup), is to give the job scheduling to join the group, and the name, convenient for us to work on which job schedule, start stop and so on.

Note: The Execute method parameter Ijobexecutioncontext executed here will automatically bring the details of job scheduling, job name, job group name, job next execution time, job execution time and so on, where the content is also very important, such as according to the job group, Job name we can find the corresponding job schedule from the database detailed, update the operational database.
2, for a job schedule to stop, start.
