ABP框架系列之四十五：(Quartz-Integration-Quartz-集成)

Introduction

Quartz is a is a full-featured, open source job scheduling system that can be used from smallest apps to large scale enterprise systems. Abp.Quartz package simply integrates Quartz to ASP.NET Boilerplate.

Quartz是一个功能齐全的开源作业调度系统，可以从最小的应用程序到大型企业系统使用。Abp.Quartz包简单地集成ASP.NET样板。

ASP.NET Boilerplate has a built-in persistent background job queue and background worker system. Quartz can be a good alternative if you have advanced scheduling requirements for your background workers. Also,Hangfire can be a good alternative for persistent background job queue.

ASP.NET的模板有一个内置的持久后台作业队列和背景工人系统。如果你对你的背景工作者有高级的进度要求，Quartz是一个不错的选择。另外，迟发性可以持续背景任务队列的一个很好的选择。

Installation

Install Abp.Quartznuget package to your project and add a DependsOn attribute to your module for AbpQuartzModule:

[DependsOn(typeof (AbpQuartzModule))]
public class YourModule : AbpModule
{
    //...
}

Creating Jobs

To create a new job, you can either implement Quartz's IJob interface, or derive from JobBase class (defined in Abp.Quartz package) that has some helper properties/methods (for logging and localization for example). A simple job class is shown below:

创建一个新的工作，你可以实现 Quartz的ijob接口，或者从jobbase类（ABP。石英包中定义的），有一些辅助属性/方法（记录和定位为例）。下面显示一个简单的作业类：

public class MyLogJob : JobBase, ITransientDependency
{
    public override void Execute(IJobExecutionContext context)
    {
        Logger.Info("Executed MyLogJob :)");
    }
}

We simply implemented the Execute method to write a log. You can see Quartz's documentation for more.

Schedule Jobs（安排工作）

IQuartzScheduleJobManager is used to schedule jobs. You can inject it to your class (or you can Resolve and use it in your module's PostInitialize method) to schedule jobs. An example Controller that schedules a job:

iquartzschedulejobmanager来安排工作。你可以将它注入到你的类（或你可以解决和使用你的模块的postinitialize法）安排工作。调度工作的示例控制器：

public class HomeController : AbpController
{
    private readonly IQuartzScheduleJobManager _jobManager;

    public HomeController(IQuartzScheduleJobManager jobManager)
    {
        _jobManager = jobManager;
    }

    public async Task<ActionResult> ScheduleJob()
    {
        await _jobManager.ScheduleAsync<MyLogJob>(
            job =>
            {
                job.WithIdentity("MyLogJobIdentity", "MyGroup")
                    .WithDescription("A job to simply write logs.");
            },
            trigger =>
            {
                trigger.StartNow()
                    .WithSimpleSchedule(schedule =>
                    {
                        schedule.RepeatForever()
                            .WithIntervalInSeconds(5)
                            .Build();
                    });
            });

        return Content("OK, scheduled!");
    }
}
