基于Asp.Net Core 5.0依赖Quartz.Net框架编写的任务调度web管理平台

 

 

 1、Quartz.NET框架核心类

IScheduler:调度者

IJobDetail:任务

ITrigger:触发器

JobKey:任务/触发器标识

JobDataMap:数据包

2、邮件通知(FluentEmail类库)

_fluentEmail.To(to).Subject(subject).Body(body, true).SendAsync();

3、Quartz.NET宿主方式,依靠IHostedService后台服务执行

internal class QuartzHostedService : IHostedService
{
	private readonly ISchedulerFactory schedulerFactory;
	private readonly IOptions<QuartzHostedServiceOptions> options;
	private IScheduler scheduler = null!;

	public QuartzHostedService(
		ISchedulerFactory schedulerFactory,
		IOptions<QuartzHostedServiceOptions> options)
	{
		this.schedulerFactory = schedulerFactory;
		this.options = options;
	}

	public async Task StartAsync(CancellationToken cancellationToken)
	{
		scheduler = await schedulerFactory.GetScheduler(cancellationToken);
		await scheduler.Start(cancellationToken);
	}

	public Task StopAsync(CancellationToken cancellationToken)
	{
		return scheduler.Shutdown(options.Value.WaitForJobsToComplete, cancellationToken);
	}
}

4.Asp.Net Core 5.0集成

		}, job =>

		return fluentEmail;
	});

	IocEngine.Instance.Init(services);  // 实在没办法才弄个静态容器获取service, 监听器里无法通过构造函数 注入 ISchedulerFactory, IFluentEmail, 猜测应该是循环引用了
