Amazon SES & Spring Boot Integration

Send emails using AWS SES and spring boot.

In this article, I will show you the steps needed to send emails from a Boot Spring app using Amazon SES or any other SMTP service.
Spring boot provides all the configuration of JavaMail by a single starter dependency. Add this following dependency to your spring boot pom.xml file.
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-mail</artifactId>
<version>2.2.5.RELEASE</version>
</dependency>
Once the dependency is in place, the next step is to specify the AWS SES properties in the application.properties file using the spring.mail.* namespace.
###################AWS SES PROPERTIES################
spring.mail.host=<host>>
spring.mail.username=<user>>
spring.mail.password=<password>>
spring.mail.properties.mail.transport.protocol=smtp
spring.mail.properties.mail.smtp.port=587
spring.mail.properties.mail.smtp.auth=true
spring.mail.properties.mail.smtp.starttls.enable=true
spring.mail.properties.mail.smtp.starttls.required=true
spring.mail.properties.mail.smtp.ssl.trust=*
When you are trying this in your local or in a non-ssl or untrusted SSL server. You may get unable to connect to host exception. So add the last line
spring.mail.properties.mail.smtp.ssl.trust=*
This will ignore the ssl check.
To get the host , username and password. Login to your AWS console and go to ses SMTP Settings and generate your credencial.

Now Make a service class(SmtpService.Java) in your project and follow this sample code.
@Service
public class SmtpService {

    @Autowired
    private JavaMailSender javaMailSender;
    public void send(Request request){
        SimpleMailMessage message = new SimpleMailMessage();
        message.setFrom(request.getFrom());
        message.setTo(request.getTo());
        message.setSubject(request.getSubject());
        message.setText(request.getBody());
        javaMailSender.send(message);
    }
}
Create a sample Model for your email payload(Request.Java)
private String to;
private String body;
private String from;
private String subject;
Now you can able to send emails. Find the comple project here
