创建定时任务

依赖库

集成

添加DependOn

csharp 复制代码

[DependsOn(typeof(AbpBackgroundWorkersHangfireModule))]
public class AppModule: AbpModule
{
}

创建ConfigureHangfire

csharp 复制代码

private void ConfigureHangfire(IServiceCollection services,IConfiguration configuration)
{
    services.AddHangfire(config =>
    {
        config.UseSqlServerStorage(configuration.GetConnectionString("Default"));
    });
    services.AddHangfireServer(o =>
    {
    	//hangfire默认15s扫一次任务，加快到1s一次。毫秒级建议用while或者重开一个abp
    	o.SchedulePollingInterval = TimeSpan.FromSeconds(1);
	});

csharp 复制代码

public override void ConfigureServices(ServiceConfigurationContext context)
{
    var services = context.Services;
    var config = context.Configuration;
    ConfigureHangfire(services,config);
}

添加dashboard

csharp 复制代码

app.UseHangfireDashboard();
app.UseConfiguredEndpoints();

此时打开http://localhost:5000/hangfire就能看到dashboard了。

创建定时任务

HighFrequencyWorker

csharp 复制代码

public class HighFrequencyWorker : AsyncPeriodicBackgroundWorkerBase
{
    public HighFrequencyWorker(AbpAsyncTimer timer, IServiceScopeFactory serviceScopeFactory) : base(timer, serviceScopeFactory)
    {
        Timer.Period = 1000;
    }

    protected override async Task DoWorkAsync(PeriodicBackgroundWorkerContext workerContext)
    {
        Logger.LogDebug("我是高频");
    }
}

CronWorker

csharp 复制代码

public class CronWorker : HangfireBackgroundWorkerBase
{
    public CronWorker()
    {
        RecurringJobId = "Cron Worker";
        CronExpression = "0 0/1 * * * ?";
    }

    public override async Task DoWorkAsync(CancellationToken cancellationToken = default)
    {
        Logger.LogDebug($"我是Cron，当前时间{DateTime.Now.ToLongTimeString()}");
    }
}

在OnApplicationInitialization里注册

csharp 复制代码

context.AddBackgroundWorkerAsync<HighFrequencyWorker>().Wait();
context.AddBackgroundWorkerAsync<CronWorker>().Wait();
