How to @Inject the factory object

[unv...@gmail.com]

Is it possible to @Inject a "factory" parameter instead of passing it as argument to create () method:

i.e. for this code to be valid and working as expected via BQ's dependecy injection mechanism? Thanks.

public class MyFactory {

    @Setter

    private int intProperty;

    @Setter

    private String stringProperty;

    @Setter

    @Inject

    private Service service;

    public OtherService create() {

        new OtherService(service)

            .setProperty(intProperty);

    }

}

Hi Vadim,

The short answer is no. We avoided that intentionally to separate "configuration"properties" and "DI services" within the factory. The alternative seemed too confusing. 

It generally works well, though I've encountered one scenario where the choice above is kinda problematic - polymorphic factories (factories that subclass each other). Each subclass may need different services to do its work, so we end up passing Injector in the method parameters, which is ugly.

So indeed we should give the factory injection a second thought. This may cut down on boilerplate in a couple of places....

That is exactly the use case I have.

I did this and works ok with me: I have the Injector as an argument to the @Provides method and then inside I am calling injector.injectMembers(serviceFactory) while looping through the values of the factories Map.
