Using Spring IoC to set up enum values

Question

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 i

Answer 1

What do you need to set up? The values are created when the class loads, and as it's an enum, no other values can be created (unless you add them to the source and recompile).

That's the point of an enum, to be able to give limit a type to an explicit range of constant, immutable values. Now, anywhere in your code, you can refer to a type Car, or its values, Car.NANO, Car.MERCEDES, etc.

If, on the other hand, you have a set of values that isn't an explicit range, and you want to be able to create arbitrary objects of this type, you'd use the same ctor as in your post, but as a regular, not enum class. Then Spring provides various helper clases to read values from some source (XML file, config file, whatever) and create Lists of that type.
