I am triying to send a mail from my spring app what was generate with jhipster 1.1.0. and my spring-boot version is 1.5.2
I have this code:
Application-dev.yml:
spring:
mail:
host: smtp.gmail.com
port: 587
username: myuser@gmail.com
password: mypass
protocol: smtp
tls: true
properties.mail.smtp:
auth: true
starttls.enable: true
#ssl.trust: smtp.gmail.com
starttls.required: true
jhipster:
mail: # specific JHipster mail property, for standard properties see MailProperties
from: myuser@gmail.com
base-url: http://127.0.0.1:8080

@Service
public class MailService {
private final Logger log = LoggerFactory.getLogger(MailService.class);
private static final String USER = "user";
private static final String BASE_URL = "baseUrl";
private final JHipsterProperties jHipsterProperties;

}

public void sendEmail(String to, String subject, String content, boolean isMultipart, boolean isHtml) {
log.debug("Send e-mail[multipart '{}' and html '{}'] to '{}' with subject '{}' and content={}",
isMultipart, isHtml, to, subject, content);
// Prepare message using a Spring helper
MimeMessage mimeMessage = javaMailSender.createMimeMessage();
try {
MimeMessageHelper message = new MimeMessageHelper(mimeMessage, isMultipart, CharEncoding.UTF_8);
message.setTo(to);
message.setFrom(jHipsterProperties.getMail().getFrom());
message.setSubject(subject);
message.setText(content, isHtml);
javaMailSender.send(mimeMessage);
log.debug("Sent e-mail to User '{}'", to);
} catch (Exception e) {
log.warn("E-mail could not be sent to user '{}'", to, e);
}
}
@Async
public void sendActivationEmail(User user) {
log.debug("Sending activation e-mail to '{}'", user.getEmail());
Locale locale = Locale.forLanguageTag(user.getLangKey());
Context context = new Context(locale);
context.setVariable(USER, user);
context.setVariable(BASE_URL, jHipsterProperties.getMail().getBaseUrl());
String content = templateEngine.process("activationEmail", context);
String subject = messageSource.getMessage("email.activation.title", null, locale);
sendEmail(user.getEmail(), subject, content, false, true);
}
@Async
public void sendCreationEmail(User user) {
log.debug("Sending creation e-mail to '{}'", user.getEmail());
Locale locale = Locale.forLanguageTag(user.getLangKey());
Context context = new Context(locale);
context.setVariable(USER, user);
context.setVariable(BASE_URL, jHipsterProperties.getMail().getBaseUrl());
String content = templateEngine.process("creationEmail", context);
String subject = messageSource.getMessage("email.activation.title", null, locale);
sendEmail(user.getEmail(), subject, content, false, true);
}
@Async
public void sendPasswordResetMail(User user) {
log.debug("Sending password reset e-mail to '{}'", user.getEmail());
Locale locale = Locale.forLanguageTag(user.getLangKey());

context.setVariable(BASE_URL, jHipsterProperties.getMail().getBaseUrl());
String content = templateEngine.process("passwordResetEmail", context);
String subject = messageSource.getMessage("email.reset.title", null, locale);
sendEmail(user.getEmail(), subject, content, false, true);
}
}
finally I use from controller this one to send mails.
Controller.java
@RestController
@RequestMapping("/api") public class MyClassResource{
private final Logger log =
LoggerFactory.getLogger(MyClassResource.class);
@Autowired
EntityManager entityManager;
@Autowired
MailService mailService;
@PostMapping ("/myurl")
@Timed
public ResponseEntity<Boolean> mymethod(@RequestBody myObject data) {
mailService.sendEmail(
"emailTo@gmail.com",
"message from spring",
"hi world. this message is from spring",
true,
true
);
}
Finally I get this error:
c....MailService : E-mail could not be sent to user 'emailTo@gmail.com'
org.springframework.mail.MailSendException: Failed messages: com.sun.mail.smtp.SMTPSendFailedException: 530 5.7.0 Must issue a STARTTLS command first. w125sm9354452wmb.45 - gsmtp

I have been reading about this error and I add some thing to configuration like is in application-dev.yml but this one doesn't work. I tried to get one password application from gmail because I read that it was necesary but I couldn't because I don have authentication by 2 steps, and finally I change to accept conexion from less secure applications and neither worked it. I don't know why doesn't work it.
