Custom message in HibernateValidator

Hi all.

I have annotated some POJO's fields with validation tags. It works fine, but the message I receive when the exception is raised is not enough intuitive. Is (easy) possible to specify a text message for each field annotation?.

E. g.:

Code:

public class AnnotatedPojo implements Serializable {

   // other fields and getter/setter...

   private String date = null;

   @Pattern(regex = Utils.DATE_REGEXP)
   public String getDate() {
      return date;
   }

   public void setDate(String date) {
      this.date = date;
   }
}

In this case, if the text written in 'date' field does not match the regular expression, Hibernate raises an error but it does not specify which is exactly the problem. I would like to indicate, at least, the field name and the source of the problem ("date format" or something similar).

Any idea?

Hi,

Use the 'message' parameter. All constraints have to support this parameter. It allows you to customize the error messages. You can add the full error message as value to parameter or you can use a token like {my.date.pattern.message} in which case you have to also create a ValidationMessages.properties file and add it to the classpath. In the properties file you use the token as key and the actual value as message.

The current distribution of Hibernate Validator contains a (not yet complete) user guide. The usage of messages is already explained. Otherwise the JSR-303 spec itself is a good place for some examples.

Ok, I have used the message parameter. It works fine.

Thank you!
