Class EmailValidator

java.lang.Object

org.hibernate.validator.internal.constraintvalidators.EmailValidator

All Implemented Interfaces:

ConstraintValidator<Email,CharSequence>

public class EmailValidator
extends Object
implements ConstraintValidator<Email,CharSequence>

Checks that a given character sequence (e.g. string) is a well-formed email address.

The specification of a valid email can be found in RFC 2822 and one can come up with a regular expression matching all valid email addresses as per specification. However, as this article discusses it is not necessarily practical to implement a 100% compliant email validator. This implementation is a trade-off trying to match most email while ignoring for example emails with double quotes or comments.
