Sending e-mails with Spring

We will create a simple Spring service that will be used for sending mail. One method will create a SimpleMailMessage on the spot, while the other will use a preconfigured default message. The source code for the service is the following:

package com.javacodegeeks.spring.mail;
 
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.mail.MailSender;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.stereotype.Service;
 
@Service("mailService")
public class MailService {
    
    @Autowired
    private MailSender mailSender;
    @Autowired
    private SimpleMailMessage alertMailMessage;
    
    public void sendMail(String from, String to, String subject, String body) {

  

  SimpleMailMessage message = new SimpleMailMessage();

   

  message.setFrom(from);

  message.setTo(to);

  message.setSubject(subject);

  message.setText(body);

  mailSender.send(message);

  
    }
    
    public void sendAlertMail(String alert) {

  

  SimpleMailMessage mailMessage = new SimpleMailMessage(alertMailMessage);

  mailMessage.setText(alert);

  mailSender.send(mailMessage);

  
    }
    
}


The corresponding Spring XML file that bootstraps the container is the following:

<?xml version="1.0" encoding="UTF-8"?>
 
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns:p="http://www.springframework.org/schema/p"
    xmlns:aop="http://www.springframework.org/schema/aop" 
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:jee="http://www.springframework.org/schema/jee" 
    xmlns:task="http://www.springframework.org/schema/task"
    xsi:schemaLocation="

    <context:component-scan base-package="com.javacodegeeks.spring.mail" />    
    
    <bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">

  <property name="host" value="smtp.gmail.com"/>

  <property name="port" value="25"/>

  <property name="username" value="myusername@gmail.com"/>

  <property name="password" value="mypassword"/>

  <property name="javaMailProperties">


<props>


    <!-- Use SMTP transport protocol -->


    <prop key="mail.transport.protocol">smtp</prop>


    <!-- Use SMTP-AUTH to authenticate to SMTP server -->


    <prop key="mail.smtp.auth">true</prop>


    <!-- Use TLS to encrypt communication with SMTP server -->


    <prop key="mail.smtp.starttls.enable">true</prop>


    <prop key="mail.debug">true</prop>


</props>

  </property>
    </bean>
    
    <bean id="alertMailMessage" class="org.springframework.mail.SimpleMailMessage">

  <property name="from">




<value>myusername@gmail.com</value>

  </property>

  <property name="to">




<value>myusername@gmail.com</value>

  </property>

  <property name="subject" value="Alert - Exception occurred. Please investigate"/>
    </bean>
    
</beans>

In case you wish to use Gmail’s SMTP server, make sure that the following JavaMail properties are configured appropriately:

host=smtp.gmail.com
port=25
username=your-gmail-username
password=your-gmail-password
mail.transport.protocol=smtp
mail.smtp.auth=true
mail.smtp.starttls.enable=true


Finally, we create a class that will be used to create the Spring container and test the simple mail service we created. The source code is the following:

package com.javacodegeeks.spring.mail;
 
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.FileSystemXmlApplicationContext;
 
public class MailServiceTest {
 
    public static void main(String[] args) {

  

  ApplicationContext context = new FileSystemXmlApplicationContext("conf/spring.xml");
 

  MailService mailService = (MailService) context.getBean("mailService");

  

  mailService.sendMail("myusername@gmail.com", "myusername@gmail.com", "Testing123", "Testing only nn Hello Spring Email Sender");

  

  mailService.sendAlertMail("Exception occurred");

  
    }
    
}
