我在MVC应用程序中使用hangfire。我正在向用户发送提醒 约定。我已经在我的应用程序中安装了hangfire。我已经在配置了hangfire startup.cs类。但是当我运行该应用程序时,它会产生以下错误, JobStorage。当前属性值尚未初始化。您必须先设置它,然后才能使用Hangfire客户端或服务器API。
using Hangfire;
using Hangfire.SqlServer;
using Microsoft.Owin;
using Owin;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using UKC.Data.Infrastructure;
using UKC.UI.Helper;
[assembly: OwinStartup(typeof(UKC.UI.App_Start.Startup))]
namespace UKC.UI.App_Start
{
public partial class Startup
{
public void Configuration(IAppBuilder app)
{
ConfigureAuth(app);
GlobalConfiguration.Configuration
.UseSqlServerStorage("DbEntities");
app.UseHangfireDashboard();
app.UseHangfireServer();
}
}
}

您可以使用这条路:
1-安装Hangfire -> Hangfire.AspNetCore(v1.7.14)和Hangfire.Core(v1.7.14)
2-注册服务
class Program
{
static void Main(string[] args)
{
BuildWebHost(args).Run();
}
public static IWebHost BuildWebHost(string[] args)
{
return WebHost.CreateDefaultBuilder(args)
.UseStartup<Startup>()
.Build();
}
}
public class Startup
{
public void ConfigureServices(IServiceCollection services)
{
// Add Hangfire services.
services.AddHangfire(configuration => configuration
.SetDataCompatibilityLevel(CompatibilityLevel.Version_170)
.UseSimpleAssemblyNameTypeSerializer()
.UseRecommendedSerializerSettings()
.UseSqlServerStorage("Server=-; Database=-; user=-; password=-;"));
// Add the processing server as IHostedService
services.AddHangfireServer();
}
3-添加仪表板用户界面
public void Configure(IApplicationBuilder app, IBackgroundJobClient
backgroundJobs, IHostingEnvironment env)
{
app.UseHangfireDashboard();
backgroundJobs.Enqueue(() => Console.WriteLine("Hello world from
Hangfire!"));
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
}
}
4-运行应用程序 由于我们创建了后台作业,因此以下消息也应出现,其唯一行为是将消息写入控制台。 Hangfire的Hello world!
答案 1 :(得分:0)
public static void InitializeHangFire()
{
var sqlStorage = new SqlServerStorage("connectionString");
var options = new BackgroundJobServerOptions
{
ServerName = "Test Server"
};
JobStorage.Current = sqlStorage;
}

this link中存在相同的问题。希望对您有帮助。
您可以编写引发异常的代码吗?我在下面编写您的Startup
类和测试控制器。工作正常。我没有遇到任何例外。
[RoutePrefix("")]
public class HomeController : ApiController
{
[Route(""), HttpGet]
public void Get()
{
Hangfire.BackgroundJob.Enqueue(() => Tasks.DoIt("test"));
Hangfire.BackgroundJob.Schedule(() => Tasks.InitializeJobs(), TimeSpan.FromSeconds(5));
}
}
public static class Tasks
{
public static void DoIt(string s)
{
Console.WriteLine(s);
}
public static void InitializeJobs()
{
Console.WriteLine(DateTime.Now.ToString());
}
}
