How to Send Email with Multiple Attachments using Amazon SES in Java Spring Boot?
In this example tutorial, you will learn how to send a plain-text or HTML-based email with multiple attachments using Amazon SES in Java Spring Boot.
Follow the steps below to send an HTML/plain-text based email with attachment using AWS SES in Java Spring Boot:
Setup SES
- Login to the AWS Management Console and open the AWS SES console at https://console.aws.amazon.com/ses.
- Create identity.
- Verify your email address with Amazon SES.
- Get your AWS credentials.
Add Dependencies
Add Java Mail Sender and Amazon SES Java SDK dependencies to your project.
For Gradle
Add the following dependency to your build.gradle file:
implementation 'org.springframework.boot:spring-boot-starter-mail'
implementation group: 'com.amazonaws', name: 'aws-java-sdk-ses', version: '1.12.12'
For Maven
Add the following dependency to your pom.xml file:
Find the other versions of AWS Java SDK for Amazon SES in the AWS SES Maven Repository.
Add Configuration Class
Create a AwsConfiguration.java class and annotate it with @Configuration. Add a method that returns an instance of AmazonSimpleEmailService class and annotate it with @Bean annotation. The following code shows how to do so:
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import com.amazonaws.auth.AWSStaticCredentialsProvider;
import com.amazonaws.auth.BasicAWSCredentials;
import com.amazonaws.services.simpleemail.AmazonSimpleEmailService;
import com.amazonaws.services.simpleemail.AmazonSimpleEmailServiceClientBuilder;
@Configuration
public class AwsConfiguration {
public AWSStaticCredentialsProvider awsCredentials() {
BasicAWSCredentials credentials =
new BasicAWSCredentials("your-aws-access-key", "your-aws-access-secret");
return new AWSStaticCredentialsProvider(credentials);
}
@Bean
public AmazonSimpleEmailService getAmazonSimpleEmailService() {
return AmazonSimpleEmailServiceClientBuilder.standard().withCredentials(awsCredentials())
.withRegion("us-east-1").build();
}
}
Send Email with Multiple Attachments
The following code shows you how to send email with multiple attachments using Amazon SES in Java:
Note: HTML based email content only support inline style css.
