background email job activate instance failed for IEmailSender dependancy missing
Closed this issue · 12 comments
i've referrenced the volo.abp.mailkit and some other necessary modules , however the email sending job always run failed. below is the error codes.
i've tried to run any other background job and got the expected work; so i can judge that the problem is the sytem couldnot find any IEmailSender instance registered . how can i fixed it.
An exception was thrown while activating xxxxHelper.Web.EmailSendingJob.
Autofac.Core.DependencyResolutionException: An exception was thrown while activating xxxxHelper.Web.EmailSendingJob.
---> Autofac.Core.DependencyResolutionException: None of the constructors found with 'Autofac.Core.Activators.Reflection.DefaultConstructorFinder' on type 'xxxxHelper.Web.EmailSendingJob' can be invoked with the available services and parameters:
Cannot resolve parameter 'Volo.Abp.Emailing.IEmailSender emailSender' of constructor 'Void .ctor(Volo.Abp.Emailing.IEmailSender)'.
the backgroundjob definition code is :
public class EmailSendingJob : BackgroundJob<EmailSendingArgs>, ITransientDependency
{
private readonly IEmailSender _emailSender;
public EmailSendingJob(IEmailSender emailSender)
{
_emailSender = emailSender;
}
// work well with the background job without IEmailSender injection
// public EmailSendingJob()
// {
//
// }
public override void Execute(EmailSendingArgs args)
{
// Logger.Log<EmailSendingArgs>(LogLevel.Information,new EventId(1001)
// ,args,null,null);
// _emailSender.SendAsync(
// args.EmailAddress,
// args.Subject,
// args.Body
// ).Wait();
Console.ForegroundColor = ConsoleColor.Blue;
Console.WriteLine("I'm triggered without IEmailSender");
Console.ForegroundColor = ConsoleColor.White;
}
}
[DependsOn(typeof(AbpEmailingModule))]
public class AbpMailKitModule : AbpModule
{
}
i found the source code of AbpMailKitModule is as simle as above, is there something wrong?
Did you [DependsOn(typeof(AbpMailKitModule))]?
ofcourse, i did that @acjh ; the issue is failed to get the the iemailsender injection .
the autofac dependency couldn't find any relevant instances
please see the module code
[DependsOn(
typeof(AbpAutofacModule),
typeof(XXXXApplicationModule),
typeof(AbpMailKitModule),
typeof(AbpBackgroundJobsModule),
typeof(AbpSettingManagementDomainModule),
typeof(AbpSettingManagementEntityFrameworkCoreModule)
)]
public class BackgroundJobTaskModule:AbpModule
{
public override void ConfigureServices(ServiceConfigurationContext context)
{
Configure<AbpBackgroundJobWorkerOptions>(options =>
{
options.DefaultTimeout = 86400; //1 days (as seconds)
//Configure for fast running
options.JobPollPeriod = 1000;
options.DefaultFirstWaitDuration = 1;
options.DefaultWaitFactor = 1;
});
Configure<AbpBackgroundJobOptions>(options =>
{
options.IsJobExecutionEnabled = true; //set to false can Disable job execution
// options.AddJob<EmailSendingJob>();
// options.AddJob<BackgroundEmailSendingJob>();
});
}
public override void OnPostApplicationInitialization(ApplicationInitializationContext context)
{
var email= context.ServiceProvider
.GetRequiredService<IEmailSender>();
}
}
I could not reproduce that.
In your OnPostApplicationInitialization method, is email set?
Can you create a repro project?
ok, i'll do it . i'll notice you ASAP. thanks
dear @acjh : it's sorry so late to upload the project.

sincere thanks
Please move the dependent modules and configuration code in BackgroundJobTaskModule to MysqlDemoWebModule.
You have defined a BackgroundJobTaskModule module but it is not used. Please check the documentation for more framework information. https://docs.abp.io/en/abp/latest/
@maliming but how to explain that without IEmailSender injection ,the background job worked well?
i think that the BackgroundJobTaskModule has been registered by the abp framework?

No.

Because your DomainModule depends on it.
