Example Code Snippets

To send emails, include the mail dependency in your Spring Boot application.

Note: I am utilizing @RequiredArgsConstructor and @Slf4j annotations in the service class with the Lombok dependency; feel free to replace them with traditional constructors and loggers if preferred.

Configuration

In the application.yml file, be sure to set the necessary properties for email configuration.

Creating the EmailService

You will need to establish an EmailService class that handles the sending of HTML enriched emails along with attachments.

Building the HTML Template

It's essential to create your email template. I recommend using a template builder for this purpose, as it simplifies the creation process and often proves more advantageous than simple text emails.

For starters, I suggest using Stripo.email (not a referral link, but a recommendation due to their free tier for smaller projects). You can select a responsive template or start from scratch.

Utilizing Stripo's code editor, you can copy the HTML code, as illustrated below.

Using HTML Templates in Your Spring Boot Application

Paste and format the HTML email template within your Spring Boot application under the templates folder. Remember, in the EmailService class, we leverage a ResourceLoader to retrieve this file from the classpath under the templates directory.

To Summarize

As demonstrated, implementing an email-sending service in a Spring Boot application with the Stripo email template builder is quite simple. Go ahead and create your template!

That's all for today! Let's get coding! ❤
