Spring – Sending E-mail via Gmail SMTP server with MailSender

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.

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);	
	}
}

3. Bean configuration file

Configure the mailSender bean and specify the email details for the Gmail SMTP server.

Note
Gmail configuration details – http://mail.google.com/support/bin/answer.py?hl=en&answer=13287

File : Spring-Mail.xml


<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">

<bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
	<property name="host" value="smtp.gmail.com" />
	<property name="port" value="587" />
	<property name="username" value="username" />
	<property name="password" value="password" />
		
	<property name="javaMailProperties">
	   <props>
       	      <prop key="mail.smtp.auth">true</prop>
       	      <prop key="mail.smtp.starttls.enable">true</prop>
       	   </props>
	</property>
</bean>
	
<bean id="mailMail" class="com.mkyong.common.MailMail">
	<property name="mailSender" ref="mailSender" />
</bean>
	
</beans>

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("[email protected]",
    		   "[email protected]",
    		   "Testing123", 
    		   "Testing only \n\n Hello Spring Email Sender");
        
    }
}

    1. I had the same issue. All you have to do is to activate lesssecureapp feature. To do so, sign in your google account and switch on that.

  11. Nice article,
    I have also used JavaMailSenderImpl for sending mail and it is running successfully.
    There is one issue i faced is that, as I am sending some critical data in mail and it gets logged in console.
    So is there any way to disable logger for not logging critical mail content or whole mail content ?
    Thanks in advance

  16. Hello,

    Would be possible to set the SMTP server dynamically? I want the user to persist this data in an embedded database once the app is deployed and, after that, configure the mailsender.

    Thank you in advance and congratulations for this great article 😉

  19. Hi,

    Thanks for this tutorial. This is really effective.
    One issue I am facing while running this code. The mail is getting delivered without the subject and from.
    Can you please let me know apart from this code do I need to do anything else.

    My Code:
    package com.cms.notification.mail;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.mail.MailSender;
    import org.springframework.mail.SimpleMailMessage;

    public class SampleMail {
    @Autowired
    private 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);

    System.out.println(“DONE”);
    }

    }

  25. Hi I’m using javamailproperties in the mail bean. I want bounced email notification to be send to another address rather than “from” address in the mail. I’m not getting error but bounced mails are not being sent either.
    bean properties

     
<bean id="MailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
        <property name="host" value="${MAIL_HOST}"/>
        <property name="port" value="${MAIL_PORT}"/>
        <property name="javaMailProperties">
            <props>
                <prop key="mail.debug">true</prop>
                <prop key="mail.transport.protocol">smtp</prop>
                <!--prop key="mail.smtp.auth">false</prop-->
                <prop key="mail.smtp.starttls.enable">false</prop>
                <prop key="mail.smtp.from">[email protected]</prop>
            </props>
        </property>
    </bean>

    java mail sender is

    public void sendMail(final MailBean p_mailBean) {
        MimeMessagePreparator l_preparator = new MimeMessagePreparator() {

            public void prepare(MimeMessage p_msg) throws Exception {
                //p_msg.setHeader("Return-Path", "<[email protected]>");

                p_msg.setRecipient(RecipientType.TO, new InternetAddress(p_mailBean.getRecipient()));                  
                if (p_mailBean.getFrom() != null && !"".equals(p_mailBean.getFrom())) {
                    p_msg.setFrom(new InternetAddress(p_mailBean.getFrom()));
                } else {
                    p_msg.setFrom(new InternetAddress(getFromAddress()));
                }
                p_msg.setSubject(p_mailBean.getSubject());
                p_msg.setContent(p_mailBean.getText(), "text/html");
            }
        };
        try {            
            this.mailSender.send(l_preparator);
        } catch (MailException me) {
            System.out.println("exception occurred");
            me.printStackTrace();
            //Doesn't rethrow the exception
            logger.error("Error sending mail to " + p_mailBean.getRecipient(), me);
            logger.error(StackTraceHandler.getTrace(me));
        }
    }

    can you help me find what is the problem please? I’ve been working on this for 2 days now 🙁
    Thank you

  27. Hi,

  30. Is there any way to know whether the email has been successfully delivered or not. I meant to say whether any bounce back message is there?

    Reply

  31. Thanks a lot, it was really useful. There is a 

    simpleMailMessage

    in the project that can be downloaded which isn’t really used (and it’s not used in the example on this page), you may want to delete in there.

  32. Do you know how to get a delivery notificaiton of an email sent by using JavaMailSenderImpl.

    I have tried to set the following properties and tried, but it doesn’t work.

    true
    true
    true
    ISO-8859-1
    “SUCCESS, FAILURE ORCPT=rfc822;[email protected]”

    1. Are you behind Firewall or proxy? Make sure your network didn’t blocked smtp.gmail.com and port 587. Often time, your company just blocked anything but port 80.

    How can i set proxy settings here, to send emails through network that uses a proxy server?
