send mail to AWS SES using spring boot

AppConfig.java

package org.test.demo;

import com.amazonaws.regions.Region;
import com.amazonaws.regions.Regions;
import com.amazonaws.services.simpleemail.AmazonSimpleEmailService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Configuration;

@Configuration
public class AppConfig {

    @Autowired
    AmazonSimpleEmailService amazonSimpleEmailService(AmazonSimpleEmailService amazonSimpleEmailService) {
        // if use ses region change, write below.
        amazonSimpleEmailService.setRegion(Region.getRegion(Regions.US_EAST_1));
        return amazonSimpleEmailService;
    }

}

MailSenderService.java

package org.test.demo.service;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.mail.MailSender;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.stereotype.Service;

@Service
public class MailSenderService {

    private final MailSender mailSender;

    @Autowired
    public MailSenderService(MailSender mailSender) {
        this.mailSender = mailSender;
    }

    public void sendMessage() {
        SimpleMailMessage simpleMailMessage = new SimpleMailMessage();
        simpleMailMessage.setFrom("from@mailaddress");
        simpleMailMessage.setTo("to@mailaddress");
        simpleMailMessage.setSubject("subject");
        simpleMailMessage.setText("text");

        this.mailSender.send(simpleMailMessage);

    }

}

pom.xml

<!-- add -->
		<dependency>
			<groupId>org.springframework.cloud</groupId>
			<artifactId>spring-cloud-starter-aws</artifactId>
		</dependency>

I think this might be broken in the latest release of the AWS SDK. amazonSimpleEmailService is immutable now and the region can't be changed.

For anyone wondering why "spring-cloud-starter-aws" dependency is not enough for this example to work:

Most of the required stuff from spring-cloud-aws-context is optional.. If you want to use that stuff (MailSender etc) within your project, you have to include optional dependencies in your project also.

For Newbies

@matthewsommer can be changed by static region

@hajdukd Can I specify the keys and region within the configuration as follows? Also I'm trying to use JavaMailSender instead of MailSender. as I need to send HTML formatted emails.

  @Autowired
    AmazonSimpleEmailService amazonSimpleEmailService(AmazonSimpleEmailService amazonSimpleEmailService) {
  	
      amazonSimpleEmailService = AmazonSimpleEmailServiceClientBuilder.standard()
              .withCredentials(new AWSStaticCredentialsProvider(new BasicAWSCredentials(ACCESSKEY, SECRETKEY)))
              .withRegion(Regions.US_EAST_1).build();
  }

Also can I replace the artifact 'spring-cloud-starter-aws' with some minimal required dependencies to work with SES on springboot?
