How to access the @AuraEnabled variables in client Controller?

Question

 public class test{

    @AuraEnabled
    Public Static Integer init1;

    @AuraEnabled
    Public Static Integer init2;

    @AuraEnabled
    public Static string returnStringOnlyButInitInteger(){
        Init1 = 10;
        Init2 = 20;
        return "I have initialized the Integers";
    }

}

If I have initialized the string variables in the Apex Controller and call the method on Component initialization. How can I access the other variables in Component ? Thanks

You can't. I think at one point Lightning was meant to have a mechanism where you'd be able to have automatic view state, like in Visualforce, but that hasn't materialized as a feature. The documentation states:

Don’t store component state in your controller (client-side or server-side). Store state in a component’s client-side attributes instead.

You are advised to store data in attributes only, and pass them back and forth as parameters and return values as necessary.
