Having troubles sending emails from spring boot application

Question

I have been trying to send email via spring boot and i cant seem to succeed. I am been using javamail api for a long time now but want to use springboot with spring mail.

public class SendMail {

    @Autowired
    private JavaMailSender javaMailSender;

    public void sendingMail(String to, String subject, String body) {
        SimpleMailMessage message = new SimpleMailMessage();
        message.setTo(to);
        message.setSubject(subject);
        message.setText(body);
        javaMailSender.send(message);
    }

}

and here is my mailer

@Controller
public class ExamPle {

    @Autowired
    private SendMail  sendMail;

    @RequestMapping("/he")
    public String homePage() {
        sendMail.sendingMail("bobobush007@gmail.com", "Welcome George", "Sample Message here");
        return "Sent";
        }
}

I already have sprint-boot-starter-mail in my pom file but i keep getting this error message. I have even watched youtube videos of tutorials on how to do this and yet it doesn't work. I am using Spring Tool Suite Version: 3.9.0.RELEASE.

Answer 1

I think the password you should use is the Generated app password for gmail, it shouldn't be just any password i guess.

Answer 2

This works.

@Service
public class SendMail {

@Autowired
private JavaMailSender javaMailSender;

  public void sendingMail(String to, String subject, String body) {
    MimeMessage message=javaMailSender.createMimeMessage();
    MimeMessageHelper helper;
    helper=new MimeMessageHelper(message,true);
    helper.setTo(to);
    helper.setSubject(subject);
    helper.setText(body);
    javaMailSender.send(message);

 }}

Answer 3

Seems your properties is not fetched properly, for example:

spring.mail.properties.mail.smtp.auth=true
spring.mail.properties.mail.smtp.starttls.enable=true

You should try to use other way like this:

JavaMailSenderImpl mailSender = new JavaMailSenderImpl();

mailSender.setHost(emailProperties.getHost());
mailSender.setPort(Integer.parseInt(emailProperties.getPort()));
mailSender.setUsername(emailProperties.getUsername());
mailSender.setPassword(emailProperties.getPassword());

Properties javaMailProperties = new Properties();
javaMailProperties.put("mail.smtp.starttls.enable", "true");
javaMailProperties.put("mail.smtp.auth", "true");
javaMailProperties.put("mail.transport.protocol", "smtp");
javaMailProperties.put("mail.debug", "true");

mailSender.setJavaMailProperties(javaMailProperties);

See more this way from the post Spring Boot Freemarker Email Template

Hope this help!

Answer 4

Have you tried adding javax.mail to your pom ? Spring email sender has a dependency to JavaMail.
