javax.validation to validate list of values?

Question

is there a way to use javax.validation to validate a variable of type string called colour that needs to have these values only(red, blue, green, pink) using annotations?

Answer 1

you can create an enum

public enum Colors {
    RED, PINK, YELLOW
}

and then in your model, you can validate it like so:

public class Model {
    @Enumerated(EnumType.STRING)
    private Colors color;
}

which will validate your payload against the enum, given that you have added @Valid in your RestController.
