SpringBoot Send Email With Attachment

Sending emails with attachments is a common requirement in many applications, including those built with Spring Boot. There are several reasons why sending emails with attachments is important in various scenarios:

1. Sharing Information: Attachments allow you to share additional information, such as documents, images, or other files, along with the email. This is useful when you need to provide more context or details related to the email content.
2. Document Distribution: In business applications, it’s often necessary to send documents like invoices, reports, or contracts via email. Attaching these files ensures that the recipient has the necessary information conveniently.
3. Enhanced Communication: Sometimes, a picture is worth a thousand words. Attaching images or diagrams can help convey information more effectively than text alone, making communication more comprehensive.
4. File Sharing: Email is a common means of sharing files, and attachments provide a way to send files directly within the email rather than relying on external file-sharing services.

Spring Boot provides the JavaMailSender interface and the MimeMessage helper class to create and send emails. You can easily attach files to your email using the MimeMessageHelper class.
