Email Document
Generate a document and attach it to an e-mail in one step. The message is a real MIME e-mail (HTML + text + PDF attachment).
Outbox mode - no SMTP server is configured, so e-mails are saved as
.eml files in
C:\GumroadArtifactsSoft\spring-boot-print-document-lab\data\outbox and nothing leaves this PC. Download one and open it with Outlook or
Thunderbird to see exactly what the customer would get. To send for real, set spring.mail.host (see the box below).
Sent / Outbox
table email_log| When | To / subject | Attachment | Status |

How it works
MimeMessage msg = mailSender.createMimeMessage(); // or new MimeMessage(Session) in Outbox mode
MimeMessageHelper h = new MimeMessageHelper(msg, true, "UTF-8"); // true = multipart (needed for attachments)
h.setFrom("PrintDoc Lab <documents@printdoc.local>");
h.setTo("accounts@siamfresh.example");
h.setSubject("Invoice INV-202610-001");
h.setText(plainText, html); // text + HTML alternative
h.addAttachment("invoice-INV-202610-001.pdf", new ByteArrayResource(pdfBytes), "application/pdf");
msg.writeTo(new FileOutputStream("data/outbox/....eml")); // Outbox
mailSender.send(msg); // SMTPSend real mail: add to config/application-local.properties
spring.mail.host=smtp.gmail.com
spring.mail.port=587
spring.mail.username=you@gmail.com
spring.mail.password=your-16-letter-app-password
spring.mail.properties.mail.smtp.auth=true
spring.mail.properties.mail.smtp.starttls.enable=trueSpring Boot only creates the JavaMailSender bean when spring.mail.host is set; the service asks
for it with ObjectProvider<JavaMailSender> and falls back to the Outbox. Files: service/EmailService.java.
