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
源码地址： https://github.com/246850/Calamus.TaskScheduler
演示地址：http://47.101.47.193:1063/
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);
}
}
