Adding Hangfire support to a solution #4032 | Support

akaziuka created 2 years ago

We have a tiered app/solution generated with ABP Suite. We're looking to add Hangfire support to this solution. Following the documentation that describes the steps (https://docs.abp.io/en/abp/latest/Background-Jobs-Hangfire), we were able to install the package with ABP CLI, as suggested. My understanding is that we don't need to do anything extra. When we run the solution it fails at runtime with the following error:

Volo.Abp.AbpInitializationException
  HResult=0x80131500

Hello, I have re-implemented Hangfire manually, as the documentation suggested, and I can even see the dashboard running. However, the DbMigrator exits with the following error:

Unhandled exception. Volo.Abp.AbpInitializationException: An error occurred during the initialize Volo.Abp.Modularity.OnApplicationInitializationModuleLifecycleContributor phase of the module Volo.Abp.Hangfire.AbpHangfireModule, Volo.Abp.HangFire, Version=6.0.1.0, Culture=neutral, PublicKeyToken=null: An exception was thrown while activating λ:Volo.Abp.Hangfire.AbpHangfireBackgroundJobServer -> λ:Hangfire.JobStorage.. See the inner exception for details.
 ---> Autofac.Core.DependencyResolutionException: An exception was thrown while activating λ:Volo.Abp.Hangfire.AbpHangfireBackgroundJobServer -> λ:Hangfire.JobStorage.
 ---> System.InvalidOperationException: JobStorage.Current property value has not been initialized. You must set it before using Hangfire Client or Server API.
   at Hangfire.JobStorage.get_Current()
   at Hangfire.HangfireServiceCollectionExtensions.<>c.<AddHangfire>b__1_0(IServiceProvider _)
   at Hangfire.HangfireServiceCollectionExtensions.<>c__DisplayClass13_0`1.&lt;TryAddSingletonChecked&gt;b__0(IServiceProvider serviceProvider)
   at Autofac.Extensions.DependencyInjection.AutofacRegistration.&lt;&gt;c__DisplayClass3_0.&lt;Register&gt;b__0(IComponentContext context, IEnumerable`1 parameters)
   ...

I'm not sure what JobStorage does it require. I'm using PostgresSQL as a database server, and I can see Hangfire has created a separate schema in the database to host its data. Any clues on what can it be?

Also, please suggest what's the proper place in the solution to implement Hangfire logic/jobs?

I have re-implemented Hangfire manually

Can you share your code?

Maybe you should move some code to DbMigrator module.
