I am fairly new to Java spring - I am getting the following errors when trying to send a test email.
Error in sending email:
org.springframework.mail.MailSendException: Mail server connection failed; nested exception is javax.mail.MessagingException: Could not connect to SMTP host: smtp.gmail.com, port: 587; nested exception is: javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connection?. Failed messages: javax.mail.MessagingException: Could not connect to SMTP host: smtp.gmail.com, port: 587; nested exception is: javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connection?; message exceptions (1) are: Failed message 1: javax.mail.MessagingException: Could not connect to SMTP host: smtp.gmail.com, port: 587; nested exception is: javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connection?"
SimepleEmailController.java
package controller;
import javax.mail.internet.MimeMessage;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.MimeMessageHelper;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
@Controller
public class SimpleEmailController {
@Autowired
private JavaMailSender sender;
@RequestMapping("/simpleemail")
@ResponseBody
String home() {
try {
sendEmail();
return "Email Sent!";
}catch(Exception ex) {
return "Error in sending email: "+ex;
}
}
private void sendEmail() throws Exception{
MimeMessage message = sender.createMimeMessage();
MimeMessageHelper helper = new MimeMessageHelper(message);
helper.setTo("[email protected]");
helper.setText("How are you?");
helper.setSubject("Hi");
sender.send(message);
}
}
The application.properties settings are as follows - testing on a test account
spring.mail.port=587
spring.mail.host=smtp.gmail.com
[email protected]
spring.mail.password=zzzzzzzzzzz
spring.mail.protocol=smtp
spring.mail.defaultEncoding=UTF-8
spring.mail.properties.mail.smtp.starttls.enable=true
spring.mail.properties.mail.smtp.auth = true
spring.mail.properties.mail.smtp.socketFactory.port = 25
spring.mail.properties.mail.smtp.socketFactory.class = javax.net.ssl.SSLSocketFactory
spring.mail.properties.mail.smtp.socketFactory.fallback = true
spring.mail.properties.mail.smtp.ssl.enable=true
[email protected]
