@Component("ui_MaxValidator") @Scope("prototype") public class MaxValidator<T extends Number> extends AbstractValidator<T>
Max validator checks that value must be less than or equal to the specified maximum.

For error message it uses template string and it is possible to use '${value}' and '${max}' keys for formatted output.

In order to provide your own implementation globally, create a subclass and register it in configuration class, for example: 

     @Bean("ui_MaxValidator")
     @Scope(BeanDefinition.SCOPE_PROTOTYPE)
     @Primary
     protected MaxValidator maxValidator(long max) {
          return new CustomMaxValidator(max);
     }
