Problem with inject dependencies service in job

[juanfaustoperalta]

Hi, sorry for my English.
I want to use a task lib in my projec with Scala 2.12 and Play 2.6. When I set up and inject dependencies of play in it, it does not work because of the error: Could not find the default constructor with no parameters in: myClass for example: class Person @Inject()(actorSystem: ActorSystem, val carService: carService) extends AbstractConfigurationJob(actorSystem). The TestJobs do work correctly. Any suggestion?

Thanks

Same issue here

I surrendered to the problem by below:

class SmsNotificationDaily @Inject()(actorSystem: ActorSystem)
extends AbstractAnnotatedJob(actorSystem) {

@Inject() var cloudResourceHandler: CloudResourceHandler = _
@Inject() var ec: BlockingExecutionContext = _

...

}

(but Guice throws a lot exceptions complaining to the dependencies, I am still search solutions for it here)

I'm running into the same issue.

@zuoky your workaround unfortunately results in java.lang.NullPointerException: null when I try call a function on the injected service.

This library is not suitable for DI. You can see the class JobClassLoader, and it use reflection to get instance of out user-defined job, not with DI.

I think the only way is to get the instance from DI by Play.current.injector.getInstance, but it is depreted after play 2.5.
