What is the best Java email address validation method?
What are the good email address validation libraries for Java? Are there any alternatives to commons validator?
Apache Commons is generally known as a solid project. Keep in mind, though, you'll still have to send a verification email to the address if you want to ensure it's a real email, and that the owner wants it used on your site.
EDIT : There was a bug where it was too restrictive on domain, causing it to not accept valid emails from new TLDs.
This bug was resolved on 03/Jan/15 02:48 in commons-validator version 1.4.1
使用官方的Java电子邮件包是最简单的：
public static boolean isValidEmailAddress(String email) {
boolean result = true;
try {
InternetAddress emailAddr = new InternetAddress(email);
emailAddr.validate();
} catch (AddressException ex) {
result = false;
}
return result;
}
Apache Commons validator can be used as mentioned in the other answers.
pom.xml:
<dependency>
<groupId>commons-validator</groupId>
<artifactId>commons-validator</artifactId>
<version>1.4.1</version>
</dependency>
build.gradle:
compile 'commons-validator:commons-validator:1.4.1'
The import:
import org.apache.commons.validator.routines.EmailValidator;
The code:
String email = "myName@example.com";
boolean valid = EmailValidator.getInstance().isValid(email);
and to allow local addresses
boolean allowLocal = true;
boolean valid = EmailValidator.getInstance(allowLocal).isValid(email);
