Question

I validate in two ways – using spring validator for custom validation and javax.validation for quick and general

Spring does things neatly, where this code will go exactly to document with given locale and extract text required.

 private Errors checkPasswordMatch(Person p, Errors errors) {
   if (!p.getPassword().equals(p.getRepeatedPassword())) {
   errors.rejectValue("password", "person.password.mismatch");
   errors.rejectValue("repeatedPassword", "person.password.mismatch");
    }
    return errors;
}

Javax is less hassle, but there is no way to produce message in different languages.

    @NotNull
    @Size(min = 10, max = 10, message = "size must be 10 characters")
    protected String birthDate;

How to advise javax to go to some GB.properties or US.properties or IT.properties file to extract messages same way spring does depending on user locale?

Answer 1

@Size(min = 10, max = 10, message = "{birthDate.size}")
protected String birthDate;

in (create one in classpath if you dont have one) ValidationMessages.properties define as birthDate.size = some message

EDIT 1:

Keep files seperate. ValidationMessages needs to be shipped/packaged along with your beans all the time unlike your app specific messages. You dont need to define a bean for ValidationMessages.properties file. It will be picked up automatically
