IBackgroundWorkerManager

[dicksonkimeu]

This is how we used to call background service classes.

in vNext the IocManager is un recognized. what am i missing here ?

[dicksonkimeu]

This is the class i want to call.

I was expecting something like this. but in vNext the IocManager is un recognized.

var workManager = IocManager.Resolve<IBackgroundWorkerManager>();

workManager.Add(IocManager.Resolve<BankingSwitchSync>());

You should check vnext's documentation. https://docs.abp.io/en/abp/latest/Dependency-Injection https://docs.abp.io/en/abp/latest

Have gone through the docs extensively, jobs are working (normal jobs) but can't see how to initialize my periodic background worker. Have been using something like this in the old framework

var workManager = IocManager.Resolve<IBackgroundWorkerManager>();
workManager.Add(IocManager.Resolve<BankingSwitchSync>());

context.ServiceProvider.GetRequiredService().Initialize()

Hello William, Where should I place this code ?

[wocar]

On the initialize of the module

You can override the OnApplicationInitializing

I don't seem to get this, would you help me with a sample code.

[wocar]

This is how I do it

I would suggest using resharper to find the right extension method, if this doesn’t work try

.GetService(typeof(IBackgroundService))

Have added this

            context.ServiceProvider.GetService(typeof(IBackgroundWorkerManager));
            context.ServiceProvider.GetRequiredService(typeof(BankingSwitchSync));

I was not able to add //context.ServiceProvider.GetRequiredService().Initialize();

When i ran the app i get error; Autofac.Core.Registration.ComponentNotRegisteredException: The requested service 'eBanking.VISA.Integration.BankingSwitchSync' has not been registered. To avoid this exception, either register a component to provide the service, check for service registration using IsRegistered(), or use the ResolveOptional() method to resolve an optional dependency.

hi @dicksonkimeu Try

public class Class : BackgroundWorkerBase
{
    public  override Task StartAsync(CancellationToken cancellationToken = default(CancellationToken))
    {
        this.Logger.LogDebug("Started background worker: " + this.ToString());
        return Task.CompletedTask;
    }

    public  override Task StopAsync(CancellationToken cancellationToken = default(CancellationToken))
    {
        this.Logger.LogDebug("Stopped background worker: " + this.ToString());
        return Task.CompletedTask;
    }
}

public class Class2 : PeriodicBackgroundWorkerBase
{
    public Class2(AbpTimer timer) : base(timer)
    {
        timer.Period = 1000; //1s
    }

    protected override void DoWork()
    {
        this.Logger.LogDebug("Class2 => DoWork..");
    }
}

public override void OnApplicationInitialization(ApplicationInitializationContext context)
{
    var app = context.GetApplicationBuilder();
    var env = context.GetEnvironment();

    context.ServiceProvider.GetRequiredService<IBackgroundWorkerManager>().Add(context.ServiceProvider.GetRequiredService<Class>());
    context.ServiceProvider.GetRequiredService<IBackgroundWorkerManager>().Add(context.ServiceProvider.GetRequiredService<Class2>());

    //....
}

Please share the relevant code.

[dicksonkimeu]

[dicksonkimeu]

Have tried in OnApplicationInitialization and the results are the same.

      context.ServiceProvider.GetRequiredService<IBackgroundWorkerManager>().Add(context.ServiceProvider.GetRequiredService<BankingSwitchSync>());
                context.ServiceProvider.GetRequiredService<IBackgroundWorkerManager>().Add(context.ServiceProvider.GetRequiredService<Class>());

Please share a project to reproduce your problem, you can use cli to create a project.

[wocar]

Maybe add ISingletonDependency to Class and change OnApplicationInitialization to OnPostApplicationInitialization
