Spring comes with a useful ‘org.springframework.mail.javamail.JavaMailSenderImpl‘ class to simplify the e-mail sending process via JavaMail API. Here’s a Maven build project to use Spring’s ‘JavaMailSenderImpl‘ to send an email via Gmail SMTP server.
Add the JavaMail and Spring’s dependency.

A Java class to send email with the Spring’s MailSender interface.
File : MailMail.java
package com.mkyong.common;
import org.springframework.mail.MailSender;
import org.springframework.mail.SimpleMailMessage;
public class MailMail
{
private MailSender mailSender;
public void setMailSender(MailSender mailSender) {
this.mailSender = mailSender;
}
public void sendMail(String from, String to, String subject, String msg) {
SimpleMailMessage message = new SimpleMailMessage();
message.setFrom(from);
message.setTo(to);
message.setSubject(subject);
message.setText(msg);
mailSender.send(message);
}
}
Configure the mailSender bean and specify the email details for the Gmail SMTP server.
