英文:
Apache commons email validator: allow plus character in e-mail
问题
使用 org.apache.commons.validator.routines.EmailValidator（1.7）来进行Java中的电子邮件验证。
在GMAIL中，用户可以使用 myname+anything@gmail.com，它将发送到 myname@gmail.com。然而，EmailValidator 不允许 + 字符。我还尝试在验证之前将 + 替换为 %2b，但也失败了。
有什么建议吗？我可以在我的 EmailValidator 实例中添加一个额外允许的字符吗？我找不到这个选项，但我猜我需要类似的东西。
附注：由于各种原因，我不太想使用自定义正则表达式。

using org.apache.commons.validator.routines.EmailValidator (1.7) for e-mail validation in Java.
In GMAIL a user is allowed to use myname+anything@gmail.com and it will go to myname@gmail.com. However, the EmailValidator does not allow the + character. I also tried replacing the + with %2b before validation but it also fails.
Any suggestions? Can I add an extra allowed character to my EmailValidator instance? Couldn't find this but guess I would need something like that.
Ps. I don't really want to go to custom regex for various reasons.

The Apache Commons EmailValidator 在处理加号时确实有效。输出结果为：true。
英文:
The Apache Commons EmailValidator does work with a plus sign.
import org.apache.commons.validator.routines.EmailValidator;
public class MapperMain {
public static void main(String[] args) {
String email = "john+Williams@ennui.co.za";
EmailValidator emailValidator = EmailValidator.getInstance();
System.out.println(emailValidator.isValid(email));
}
}
Outputs:
true
