Simplify.Scheduler Documentation
Same as Simplify.WindowsServices library with removed Windows Services
dependency and specifically made for console (docker) execution.
Provides BasicScheduler
, SingleTaskScheduler
, MultitaskScheduler
classes for scheduling.
Allows you to simply create applications which can work on schedule. Every user class instance will be instantiated using Simplify.DI IOC container which provides DI by default for your application.
Available at NuGet as binary package
Principle of work
To use Simplify.Scheduler, you must create a class with the Run
method in it and pass this class to the handler as a type parameter. The Run
method will be invoked by the handler class (the handler types are listed below), this method will be your execution process root. An instance of your class will be created using the IOC Simplify.DI
container, so you can register any types that your class depends on through DIContainer.Current
, and they will be automatically resolved.
Run
method can be one of the following:
- Parameterless
Run()
method. Run(string serviceName)
if you want to access a service name.Run(IJobArgs args)
if you want to access a service name or startup parameters.
Run method can be void
or can return Task
(can be used for async/await code).
Quick start
There is a templates package available at nuget.org for Simplify.Scheduler.
Install Simplify.ProjectsTemplates
templates package:
dotnet new -i Simplify.ProjectsTemplates
Create an initial Simplify.Scheduler based project:
dotnet new simplify.scheduler -n HelloWorld
Types of Schedulers
BasicScheduler
BasicScheduler
class is best suited for services that run without timers, for example, a TCP server or client.
SingleTaskScheduler
SingleTaskScheduler
class is best suited to perform one task, which must be periodically started by a timer.
MultitaskScheduler
MultitaskScheduler
class is best suited for multiple tasks services.
This is the same as SingleTaskScheduler
but allows you to specify multiple working classes/methods.
You can add multiple jobs with different timer intervals/crontab expressions.
You can use single class with several methods, each specified method will be launched by the corresponding task (a new instance of the class will be created), or simply use several classes.
MultitaskScheduler working example
Setup a job schedule
You can specify timer intervals in seconds or just set the Ncrontab expression for timer. If no settings specified in the configuration, then the timer will be executed once every minute. If both timer interval and crontab expression specified in the config, then the crontab expression will be used instead.
Multiple crontab expressions can be specified, for example: 30 14 * * *|45 1 * * *|0 12 * * Mon
The main way to setup a job is to pass configuration based on Microsoft.Extensions.Configuration.IConfiguration
Example
Program.cs
var configuration = new ConfigurationBuilder()
.AddJsonFile("appsettings.json", false)
.Build();
using(var handler = new SingleTaskScheduler<MyClass>(configuration))
handler.Start();
appsettings.json
{
"JobSettings":
{
"CrontabExpression": "* * * * *",
"ProcessingInterval: 30
}
}
Additional settings
Option | default value | Description |
---|---|---|
CleanupOnTaskFinish | true | Execute GC.Collect(); after each "Run" method execution |
MaximumParallelTasksCount | 1 (so the only one task of the same job can exist at a time) | The maximum allowed parallel tasks of the same job (the new task will be create in parallel if previous task is not ended execution) |
Global exceptions catching which can be thrown when resolving instances by Simplify.DI in handler
Simplify.Scheduler
can catch all exceptions thrown by user code.
To receive such an event you should subscribe to handler OnException event.
static void Main(string[] args)
{
...
handler.OnException += OnException;
...
}
static void OnException(ServiceExceptionArgs args)
{
Console.Write(args.ServiceName);
Console.Write(args.Exception.Message);
}
Examples
BasicScheduler
MyClass.cs
public class MyClass
{
public void Run()
{
// Some task
}
}
Program.cs
static void Main(string[] args)
{
DIContainer.Current.Register<MyClass>();
using(var scheduler = new BasicScheduler<MyClass>())
scheduler.Start(args)
}
SingleTaskScheduler
static void Main(string[] args)
{
DIContainer.Current.Register<MyClass>();
using(var scheduler = new SingleTaskScheduler<MyClass>)
scheduler.Start(args);
}
MultitaskScheduler
Program.cs
static void Main(string[] args)
{
// Registering in IOC container
DIContainer.Current.Register<TaskProcessor1>();
DIContainer.Current.Register<TaskProcessor2>();
// Handler creation
using(var handler = new MultitaskScheduler())
{
// Jobs addition
// If configuration section is not specified then 'YourClassName + Settings' section name will be used
handler.AddJob<TaskProcessor1>();
// Manually specified section name and invoke method name
handler.AddJob<TaskProcessor1>("TaskProcessor1SecondTaskSettings", "RunTask2");
handler.AddJob<TaskProcessor2>();
handler.Start(args);
}
}
TaskProcessor1.cs
public class TaskProcessor1
{
public void Run()
{
Debug.WriteLine("TaskProcessor1 Run executed");
}
public void RunTask2()
{
Debug.WriteLine("TaskProcessor1 RunTask2 executed");
}
}
TaskProcessor2.cs
public class TaskProcessor2
{
public void Run()
{
Debug.WriteLine("TaskProcessor2 Run executed");
}
}
appsettings.json
{
"TaskProcessor1Settings": {
"CrontabExpression": "*/2 * * * *"
},
"TaskProcessor1SecondTaskSettings": {
"ProcessingInterval": 30
},
"TaskProcessor2Settings": {
"ProcessingInterval": 45
}
}
