I have a Java backend with Spring MVC and I am using validation in this way on my domain object for an email address:
import javax.validation.constraints.NotNull;
import javax.validation.constraints.Pattern;
import javax.validation.constraints.Size;
...
@NotNull
@Size(min = 1, max = 100)
@Pattern(regexp="^([a-zA-Z0-9\\-\\.\\_]+)'+'(\\@)([a-zA-Z0-9\\-\\.]+)'+'(\\.)([a-zA-Z]{2,4})$")
private String email;
But all I get with these lines of code
Set<ConstraintViolation<Person>> failures =
validator.validate(personObject);
...
Map<String, String> failureMessages = new HashMap<String, String>();
for (ConstraintViolation<Person> failure : failures) {
failureMessages.put(failure.getPropertyPath().toString(), failure.getMessage());
System.out.println(failure.getPropertyPath().toString()+" - "+failure.getMessage())
}
I get this on the console:
email - must match "^([a-zA-Z0-9\\-\\.\\_]+)'+'(\\@)([a-zA-Z0-9\\-\\.]+)'+'(\\.)([a-zA-Z]{2,4})$"
but I have as email address
[email protected], so the regexp does not match.
So I have two prolems:
What's wrong here?
And how can I define a error message on my own, because display this to the user, that is not a good thing :-)
Thank you in advance for your help and Best Regards.
