nuget

Hangfire.AspNetCore

Hangfire.MySqlStorage

我使用的是mysql  同时hangfire也支持sqlserver 所以他可以持久化

using Hangfire;
using Hangfire.MySql;
using HangFire;
using System.Transactions;

var builder = WebApplication.CreateBuilder(args);
 7 builder.Services.AddHangfire(options =>
 8 {
 9     string hangFireConStr = builder.Configuration.GetSection("hangFireConStr").Value;
10     options.UseStorage(new MySqlStorage(hangFireConStr, new MySqlStorageOptions
11     {
12         TransactionIsolationLevel = IsolationLevel.ReadCommitted,//TransactionIsolationLevel - 事务隔离级别。默认值为已提交读取。
13         QueuePollInterval = TimeSpan.FromSeconds(15),    //QueuePollInterval - 作业队列轮询间隔。默认值为 15 秒。
14         JobExpirationCheckInterval = TimeSpan.FromHours(1),    //JobExpirationCheckInterval - 作业过期检查间隔（管理过期记录）。默认值为 1 小时。
15         CountersAggregateInterval = TimeSpan.FromMinutes(5),    //CountersAggregateInterval - 聚合计数器的间隔。默认值为 5 分钟。
16         PrepareSchemaIfNecessary = true,    //PrepareSchemaIfNecessary - 如果设置为 ，则创建数据库表。默认值为 。truetrue
17         DashboardJobListLimit = 50000,    //DashboardJobListLimit - 仪表板作业列表限制。默认值为 50000。
18         TransactionTimeout = TimeSpan.FromMinutes(1),    //TransactionTimeout - 事务超时。默认值为 1 分钟。
19         TablesPrefix = "Hangfire"    //TablesPrefix - 数据库中表的前缀。默认值为无
20     }));
21 });
22 //注入核心服务
23 builder.Services.AddHangfireServer();
24 //注入 hangfire 后台服务
25 builder.Services.AddHostedService<RecurringJobsService>();
26 // Add services to the container.

builder.Services.AddControllers();
// Learn more about configuring Swagger/OpenAPI at https://aka.ms/aspnetcore/swashbuckle
builder.Services.AddEndpointsApiExplorer();
builder.Services.AddSwaggerGen();

var app = builder.Build();
34 //hangfire面板
35 app.UseHangfireDashboard();
// Configure the HTTP request pipeline.
if (app.Environment.IsDevelopment())
{
    app.UseSwagger();
    app.UseSwaggerUI();
}

app.UseHttpsRedirection();

app.UseAuthorization();

app.MapControllers();

app.Run();

 

后台任务
