Is there a way to set up such enum values via Spring IoC at construction time?

What I would like to do is to inject, at class load time, values that are hard-coded in the code snippet below:

public enum Car {         NANO ('Very Cheap', 'India'),         MERCEDES ('Expensive', 'Germany'),         FERRARI ('Very Expensive', 'Italy');          public final String cost;         public final String madeIn;          Car(String cost, String madeIn)         {                 this.cost= cost;                 this.madeIn= madeIn;         }  }

Let’s say that the application must be deployed in Germany, where Nanos are ‘Nearly free’, or in India where Ferraris are ‘Unaffordable’. In both countries, there are only three cars (deterministic set), no more no less, hence an enum, but their ‘inner’ values may differ. So, this is a case of contextual initialization of immutables.

  1. Do you mean setting up the enum itself?

    I don’t think that’s possible. You cannot instantiate enums because they have a static nature. So I think that Spring IoC can’t create enums as well.

    On the other hand, if you need to set initialize something with a enum please check out the Spring IoC chapter. (search for enum) There’s a simple example that you can use.
