Should mapping value be declared in a contant or as an enum?
===

I see this scattered throughout code base : 

@RequestMapping(value = "myValue")

I would prefer to use something like this : 

@RequestMapping(value = Constants.myValue)

It seems to break DRY using the actual String value within @RequestMapping instead of constant
But is this good code practice ? Should I use an enum instead ?
I may need to use Constants.myValue elsewhere in the code base
