Beginner questions related to the official tutorial

[Thomas Lehmann]

Hi,

what I'm basically have been looking for was a comfortable way of using a factory

where the factory does not know directly the implementation.

Main point is that in my project I have very strict rules from Checkstyle and

PMD complaining if one class does know too many others.

Now looking at the tutorial from your side - coming to my questions - I wondered

about at least two things:

1. The whole thing does work only if I specify the list of modules at the component annotation. Is this not the opposite to what I mentioned about loosely coupled classes? At least from tutorial there is one module per command ... Isn't there a way to work without that?
   
   
2. In the tutorial the command is created once and then used to route the input to that command. How to change that when I need a new command of same type for each routing operation? (in my case I have tasks being read from a document and I need the "new Task" instance mechanism on each task I find in the document depending on the type of task.

I think that it's for the beginning :)

Kind Regards,

Thomas

1. @Modules.includes allows you to compose modules if that's what you're looking for. But be careful to make logical groupings; it's not necessarily an antipattern to have a long list of modules in your component. It's often easiest to think about groupings of modules once you start having multiple configurations/components.
   
2. Instead of requesting a Map<String, Command>, you can request a Map<String, Provider<Command>>. Once you have the appropriate Provider<Command>, calling provider.get() multiple times will give you multiple instances.
