Sending Email with Attachments in Spring Boot

I'm trying to send an email with file attachments in Spring Boot.

This is a basic gmail SMTP server application properties config:

This is my EmailService:

EmailService

When I call this method with mailMessageDto object passed, there is no exception thrown. Nothing happens, e-mail isn't sent.

I have debugged on javaMailSender.send(messsage) line of code and everything seems fine.

Update

spring.mail.properties.mail.smtp.ssl.enable=false

should be false not true spring.mail.properties.mail.smtp.socketFactory.class=javax.net.ssl.SSLSocketFactory

step 1. add dependencies in porm.xml

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-mail</artifactId>
</dependency>

step 2. add configuration code in application.properties

spring.mail.host=smtp.gmail.com
spring.mail.port=465
spring.mail.username=username
spring.mail.password=password
spring.mail.protocol=smtps
spring.mail.properties.mail.smtp.auth=true
spring.mail.properties.mail.smtp.connectiontimeout=5000
spring.mail.properties.mail.smtp.timeout=5000
spring.mail.properties.mail.smtp.writetimeout=5000
spring.mail.properties.mail.smtp.starttls.enable=true

step 3. add code in controller masterconroller.java

@GetMapping("/sendmail")
@ResponseBody
String home() {
    try {
        masterServiceImpl.sendEmail("path");
        return "Email Sent!";
    } catch (Exception ex) {
        return "Error in sending email: " + ex;
    }
}

step 4. add code in MasterServiceImpl.java

@Autowired
private JavaMailSender javaMailSender;
public void sendEmail(String path) throws Exception{
         MimeMessage message = javaMailSender.createMimeMessage();
         MimeMessageHelper helper = new MimeMessageHelper(message, true);
         helper.setTo("[email protected]");
         helper.setText("<html><body><h1>hello Welcome!</h1><body></html>", true);
         FileSystemResource file  = new FileSystemResource(new File(path));
         helper.addAttachment("testfile", file);
         helper.addAttachment("test.png", new ClassPathResource("test.jpeg"));
         helper.setSubject("Hi");
         javaMailSender.send(message);
   }

I propose you to apply SRP to sendMessageWithAttachment() method by extracting functionality around adding attachments:

private void addAttachments(MailMessageDto message, MimeMessageHelper helper) {
  message.getFiles().forEach(file -> addAttachment(file, helper));
}

This method streams over all files and adds every file by using addAttachment():

private void addAttachment(File file, MimeMessageHelper helper) {
  String fileName = file.getName();
  try {
    helper.addAttachment(fileName, file);
    log.debug("Added a file atachment: {}", fileName);
  } catch (MessagingException ex) {
    log.error("Failed to add a file atachment: {}", fileName, ex);
  }
}

This will log an error for each failed attachment. Can you try this approach?
