Configuring max and min parameters in @size validation annotation through properties












0















Normally, we would validate a model with some constraint like so:



public class PersonForm {
@NotNull
@Size(min=2, max=30)
private String name;

@NotNull
@Min(18)
private Integer age;
}


However, I would like to use configurable properties instead of constants in my implementation. For instance, let this the properties file:



personform.name.size.min=2
personform.name.size.max=30


and the form class...



public class PersonForm {
@NotNull
@Size(min="personform.name.size.min", max="personform.name.size.max")
private String name;

...
}


Is this possible with a declarative, annotation-based approach? Thank you.

          Try using Spring Expression language in annotation



           @Size(min="${personform.name.size.min}", max="${personform.name.size.max}")
          private String name;
