1、介绍
Hangfire是一个开源的.NET任务调度框架,提供了内置集成化的控制台(后台任务调度面板),可以直观明了的查看作业调度情况。
2、Nuget安装
3、编写代码
1)测试服务:FirstStartService
using Microsoft.Extensions.Hosting;
namespace HangfireTest.Service
{
public class FirstStartService: IHostedService
{
public async Task StartAsync(CancellationToken cancellationToken)
{
await Task.Run(() =>
{
Console.WriteLine("FirstStartService......StartAsync");
}, cancellationToken);
//hangfire定时任务
var id = Hangfire.BackgroundJob.Enqueue(() => Console.WriteLine("插入队列的任务"));
Hangfire.BackgroundJob.Schedule(() => Console.WriteLine("延迟的任务"), TimeSpan.FromSeconds(5));
Hangfire.RecurringJob.AddOrUpdate(() => Console.WriteLine("循环执行的任务"), Hangfire.Cron.Minutely);
Hangfire.BackgroundJob.ContinueJobWith(id, () => Console.WriteLine("指定任务执行之后执行的任务"));
}
public async Task StopAsync(CancellationToken cancellationToken)
{
await Task.Run(() =>
{
Console.WriteLine("FirstStartService......StopAsync");
}, cancellationToken);
}
}
}
2) 测试服务:SecondStartService
using Microsoft.Extensions.Hosting;
namespace HangfireTest.Service
{
public class SecondStartService: IHostedService
{
public async Task StartAsync(CancellationToken cancellationToken)
{
await Task.Run(() =>
{
Console.WriteLine("SecondStartService......StartAsync");
}, cancellationToken);
}
public async Task StopAsync(CancellationToken cancellationToken)
{
await Task.Run(() =>
{
Console.WriteLine("SecondStartService......StopAsync");
}, cancellationToken);
}
}
}
3)Startup.cs注入测试服务和Hangfire(此实例项目为VS2022 .NET6所建的ASP.NET Core Web API测试项目 Program.cs和其他版本建的项目有所区别,但注入方式没区别)
/// <summary>
/// 应用程序的入口点和生命周期 -- 应用程序启动起处理的任务
/// </summary>
builder.Services.AddHostedService<FirstStartService>();
builder.Services.AddHostedService<SecondStartService>();
/// <summary>
/// Hangfire定时任务
/// </summary>
builder.Services.AddHangfire(x => x.UseSqlServerStorage("Data Source=localhost;Initial Catalog=Test;Integrated Security=True;")); // SqlServer
builder.Services.AddHangfireServer();
/// <summary>
/// Hangfire定时任务
/// </summary>
app.UseHangfireDashboard();
4、访问方式
