Query parameter enums are generated as Strings

raml like this:

#%RAML 1.0
title: Query parameter enums are generated as Strings #291

/bus:
  get:
    queryParameters:
      brandName:
        type: string
        enum: [Volvo, Scania]

will generated method where brandName is a String.
BrandName enum will be generated but not referenced.

If brandName is a data type enum will be referenced as it should be.

It seems that enum as @RequestParam is not handled well in Spring. E.g. if enum contains 2 constants like this:

public enum Test{
   A("a"), B("b")
   ...
}

request param value will have to match to constant name instead of constant value (in this example request param value has to be upper case). Some binder has to be added to controller but this is too cumbersome to support.

Despite limitation explained above I'll fix:

• enum query parameter defined as string
• @Valid annotation missing from interface in case of Spring4ControllerDecoratorRule
