@Component("flowui_RegexpValidator") @Scope("prototype") public class RegexpValidator extends AbstractValidator<String> implements org.springframework.beans.factory.InitializingBean
Regexp validator checks that String value is matched with specified regular expression.

The regular expression follows the Java regular expression conventions.

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

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

     @Bean("flowui_RegexpValidator")
     @Scope(BeanDefinition.SCOPE_PROTOTYPE)
     @Primary
     protected RegexpValidator regexpValidator(String regexp) {
          return new CustomRegexpValidator(regexp);
     }
