How to introduce pojo dependencies using dagger 2?

Question

I have a simple pojo class:

public class MySimpleClass {

    private List<String> mDependency;

    public MySimpleClass (List<String> dependency) {
        mDependency = dependency;
    }
}

And I'm trying to create it using dependency injection using dagger 2. Now I have a simple module and component for it:

@Module
public class MySimpleClassModule {

    @Provides
    MySimpleClass provideMySimpleClass(List<String> dependency) {
        return new MySimpleClass(dependency);
    }
}

@Component(modules={MySimpleClassModule.class})
public interface MySimpleClassComponent {
}

But I'm not sure how I can inject a dependency List<String>every time I need to create a new instance MySimpleClass. In the above scenario, it seems that I really need to add List<String>to the constructor MySimpleClassModuleand have a new instance of this module every time I need a new instance MySimpleClasswith a new one List<String>. It's right? In this particular case, this seems like a lot of overhead.

, @Inject. Dagger 2 , , @Provides .

public class MySimpleClass {

    private List<String> mDependency;

    @Inject
    public MySimpleClass (List<String> dependency) {
        mDependency = dependency;
    }
}
