Hibernate Validator - @Length - How to specify separate message for min and max?

Question

I am using Hibernate validator for form validation in my web-app. I am using the @Length annotation for my String attribute as follows:

@Length(min = 5, message

You can specify several @Length constraints at one element by using the inner list annotation (which is defined for each constraint type in Bean Validation/Hibernate Validator) like this:

@List({
    @Length(min = 5, message = "The field must be at least 5 characters"),
    @Length(max = 50, message = "The field must be less than 50 characters")
})
private String myString;

Btw. I recommend to prefer @Size as defined by the Bean Validation API over @Length for portability reasons.
