.NET 6 + Hangfire 实现后台作业管理

一.环境：

ASP.NET Core 6  Hangfire MySQL

二、新建ASP.NET Core空项目

项目名称：HangfireExample

框架：.NET 6.0

三、Nuget引入程序集

Hangfire.Core

Hangfire.MySqlStorage                   --mysql数据库存储

Hangfire.AspNetCore                     --AspNetCore支持

Hangfire.Dashboard.BasicAuthorization   --可视化 权限控制

Hangfire.HttpJob                        --httpJob

创建MySQL数据库：hangfiredb

appsettings.json配置MySQL连接：

代码语言：javascript复制

"ConnectionStrings": {
    "HangfireConnection": "server=192.168.5.234;Database=hangfiredb;userid=root;password=123456;SslMode=none;Allow User Variables=true;"
  },

Programe.cs程序：

代码语言：javascript复制

using Hangfire;
using Hangfire.Dashboard.BasicAuthorization;
using Hangfire.HttpJob;
using Hangfire.MySql;
using System.Configuration;
using System.Transactions;
using static System.Net.WebRequestMethods;



var builder = WebApplication.CreateBuilder(args);
var Config = builder.Configuration;
// Add Hangfire services.
builder.Services.AddHangfire(configuration => configuration
    .SetDataCompatibilityLevel(CompatibilityLevel.Version_170)
    .UseSimpleAssemblyNameTypeSerializer()
    .UseRecommendedSerializerSettings()
    .UseStorage(new MySqlStorage(
        Config["ConnectionStrings:HangfireConnection"],
        new MySqlStorageOptions
        {
            TransactionIsolationLevel = IsolationLevel.ReadCommitted,
            QueuePollInterval = TimeSpan.FromSeconds(15),
            JobExpirationCheckInterval = TimeSpan.FromHours(1),
            CountersAggregateInterval = TimeSpan.FromMinutes(5),
            PrepareSchemaIfNecessary = true,
            DashboardJobListLimit = 50000,
            TransactionTimeout = TimeSpan.FromMinutes(1),
            TablesPrefix = "Hangfire"
        })).UseHangfireHttpJob());

// Add the processing server as IHostedService
builder.Services.AddHangfireServer();


var app = builder.Build();
app.UseHangfireDashboard("/hangfire", new DashboardOptions
{
    Authorization = new[] {new BasicAuthAuthorizationFilter(new BasicAuthAuthorizationFilterOptions
    {
        RequireSsl = false,
        SslRedirect = false,
        LoginCaseSensitive = true,
        Users = new []
        {
            new BasicAuthAuthorizationUser
                    {
                        Login = "admin",
                        PasswordClear =  "admin"
                    }
        }
    })}
    
    app.UseRouting();
app.UseEndpoints(endpoints =>
{
    endpoints.MapGet("/", async context =>
    {
        await context.Response.WriteAsync("Hello World!");
    });
});

//app.MapGet("/", () => "Hello World!");

app.Run();

运行项目：

Hangfire运行结果

hangfire访问地址链接，输入账号admin，密码admin

https://localhost:5001/hangfire

Hangfire管理后台

自动创建了数据库表：

hangfiredb

【小结】

Hangfire是当今最流行的任务调度框架之一，大型系统中常常会用到。
