asp.net core中使用quartz定时任务

官网：https://www.quartz-scheduler.net/

添加依赖

<PackageReference Include="Quartz.AspNetCore" Version="3.5.0" />

创建一个任务类

public class HelloJob : IJob
{
    public async Task Execute(IJobExecutionContext context)
    {
        //ConsoleUtil.WriteLine("Greetings from HelloJob!");
        // Console.WriteLine(666);
    }
}

在program中注册

serviceCollection.AddQuartz(q =>
{
    // handy when part of cluster or you want to otherwise identify multiple schedulers
    q.SchedulerId = "Scheduler-Core";

    // we take this from appsettings.json, just show it's possible
    // q.SchedulerName = "Quartz ASP.NET Core Sample Scheduler";
    // as of 3.3.2 this also injects scoped services (like EF DbContext) without problems
    q.UseMicrosoftDependencyInjectionJobFactory();

    // or for scoped service support like EF Core DbContext
    // q.UseMicrosoftDependencyInjectionScopedJobFactory();
    q.UseDefaultThreadPool(tp => { tp.MaxConcurrency = 10; });
    
    // quickest way to create a job with single trigger is to use ScheduleJob
    // (requires version 3.2)
    q.ScheduleJob<HelloJob>(trigger => trigger
        //.WithIdentity("trigger3", "group1")
        // 5s一次
        .WithCronSchedule("0/5 * * * * ? ")
    );
});

// ASP.NET Core hosting
serviceCollection.AddQuartzServer(options =>
{
    // when shutting down we want jobs to complete gracefully
    options.WaitForJobsToComplete = true;
});
