Spring – Sending E-Mail Via Gmail SMTP Server With MailSender--reference
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.
1. Project dependency
Add the JavaMail and Spring’s dependency.
File : pom.xml
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.mkyong.common</groupId> <artifactId>SpringExample</artifactId> <packaging>jar</packaging> <version>1.0-SNAPSHOT</version> <name>SpringExample</name> <url>http://maven.apache.org</url> <repositories> <repository> <id>Java.Net</id> <url>http://download.java.net/maven/2/</url> </repository> </repositories> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>3.8.1</version> <scope>test</scope> </dependency> <!-- Java Mail API --> <dependency> <groupId>javax.mail</groupId> <artifactId>mail</artifactId> <version>1.4.3</version> </dependency> <!-- Spring framework --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring</artifactId> <version>2.5.6</version> </dependency> </dependencies></project>
2. Spring’s Mail Sender
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); }}<iframe id="aswift_1" name="aswift_1" frameborder="0" marginwidth="0" marginheight="0" scrolling="no" width="728" height="90"></iframe>
3. Bean configuration file
Configure the mailSender bean and specify the email details for the Gmail SMTP server.

4. Run it
package com.mkyong.common; import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext; public class App { public static void main( String[] args ) { ApplicationContext context = new ClassPathXmlApplicationContext("Spring-Mail.xml"); MailMail mm = (MailMail) context.getBean("mailMail"); mm.sendMail("from@no-spam.com", "to@no-spam.com", "Testing123", "Testing only \n\n Hello Spring Email Sender"); }}referenc from：http://www.mkyong.com/spring/spring-sending-e-mail-via-gmail-smtp-server-with-mailsender/
