设置Hangfire成功作业到期属性不起作用 [英] Set Hangfire succeeded job expiry attribute not working

问题描述

我正在使用Hangfire来执行作业，并且我想更改一天后从数据库中删除成功的作业的行为-我希望将它们存储一年.

I am using Hangfire to do jobs, and I'd like to change the behaviour that succeeded jobs are deleted from the database after a day - I'd like them to be stored for a year.

按照此中的说明进行操作线程，与

Following the instructions in this thread, which is the same as in this SO question, I have created a class:

public class OneYearExpirationTimeAttribute : JobFilterAttribute, IApplyStateFilter
{
    public void OnStateUnapplied(ApplyStateContext context, IWriteOnlyTransaction transaction)
    {
        context.JobExpirationTimeout = TimeSpan.FromDays(365);
    }

    public void OnStateApplied(ApplyStateContext context, IWriteOnlyTransaction transaction)
    {
        context.JobExpirationTimeout = TimeSpan.FromDays(365);
    }
}

并将其注册到我的Asp.net Web API启动类中作为全局过滤器:

and I register it in my Asp.net web api startup class as a global filter:

public class Startup
{
    public void Configuration(IAppBuilder app)
    {
        // ... other stuff here ...
        GlobalJobFilters.Filters.Add(new OneYearExpirationTimeAttribute());
        GlobalConfiguration.Configuration.UseSqlServerStorage("HangFireDBConnection");
        app.UseHangfireDashboard();
    }
}

网络api是发布作业的地方(即，调用BackgroundJob.Enqueue(() => ...)的地方).我尚未更改执行实际工作的客户端的配置.

The web api is the place where jobs are posted (i.e., the call to BackgroundJob.Enqueue(() => ...) happens). I have not changed the configuration of the clients that do the actual jobs.

如果我现在发布一项工作并且成功完成，那么它仍然有一天有效期，如您在屏幕快照中所见，该屏幕快照同时显示了仪表板和HangfireDb中的条目，

If I now post a job and it succeeds, it still has a expiry of one day as you can see in the screenshot, which shows both the dashboard and the entry in the HangfireDb,

我做错了什么或我想念什么?

What am I doing wrong or what am I missing?

推荐答案

我的设置错误是该属性是在错误的应用程序上设置的.正如我在问题中所述，我将过滤器添加到了发布工作的asp.net网络api的startup.cs文件中.

My mistake in setup was that the attribute was set on the wrong application. As I stated in the question, I added the filter in the startup.cs file of the asp.net web api where jobs are posted.

相反，我应该在正在执行作业的控制台应用程序中添加配置，即我的控制台应用程序以

Instead I should have added the configuration in the Console application where the jobs are being executed, i.e., my console app starts with

static void Main(string[] args)
{
    GlobalConfiguration.Configuration.UseSqlServerStorage("HangFireDBConnection");
    GlobalJobFilters.Filters.Add(new OneYearExpirationTimeAttribute());
    // ... more stuff ...
}

然后它起作用. Hangfire文档可能会更清楚地说明应在何处配置过滤器.

Then it works. The Hangfire documentation could be a bit clearer on where the filter should be configured.
