I am working on user registration function.Now I headed a new problem.
I want to send an Email to user after user done with the Registration.
#PostMapping("registration")
public String registration(Model model,
#Valid #ModelAttribute("cool") User user,
BindingResult bindingresult) {
if (bindingresult.hasErrors()) {
model.addAttribute("cool", user);
return "registration";
}
model.addAttribute("user", user);
data.addUser(user);
//------------------------Email----------------//
// Here I need a solution
//------------------------Email----------------//
return "success";
}
For example:
my Email Address is: Vincent#gmail.com
I want to send an Email from my Email(or from localhost) to User's Email.
You can use Gmail SMTP via TLS
private static String USER_NAME = "Gmail Username"; // GMail user name (just the part before "#gmail.com")
private static String PASSWORD = "gbxxfgfhujdfqndd"; // GMail password
public static boolean sendEmail(String RECIPIENT, String sub, String title, String body, String under_line_text,
String end_text) {
String from = USER_NAME;
String pass = PASSWORD;
String[] to = {
RECIPIENT
}; // list of recipient email addresses
String subject = sub;
Properties props = System.getProperties();
String host = "smtp.gmail.com";
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.host", host);
props.put("mail.smtp.user", from);
props.put("mail.smtp.password", pass);
props.put("mail.smtp.port", "587");
props.put("mail.smtp.auth", "true");
Session session = Session.getDefaultInstance(props);
MimeMessage message = new MimeMessage(session);
try {
message.setFrom(new InternetAddress(from));
InternetAddress[] toAddress = new InternetAddress[to.length];
// To get the array of addresses
for (int i = 0; i < to.length; i++) {
toAddress[i] = new InternetAddress(to[i]);
}
for (int i = 0; i < toAddress.length; i++) {
message.addRecipient(Message.RecipientType.TO, toAddress[i]);
}
message.setSubject(subject);
BodyPart messageBodyPart = new MimeBodyPart();
String htmlText = "<div style=\" background-color: white;width: 25vw;height:auto;border: 20px solid grey;padding: 50px;margin:100 auto;\">\n" +
"<h1 style=\"text-align: center;font-size:1.5vw\">" + title + "</h1>\n" + "<div align=\"center\">" +

under_line_text + "</h3><br><h4 style=\"text-align: center;font-size:0.7vw\">" + end_text +
" </h4></div>";
messageBodyPart.setContent(htmlText, "text/html");
Multipart multipart = new MimeMultipart();
// Set text message part
multipart.addBodyPart(messageBodyPart);
message.setContent(multipart);
Transport transport = session.getTransport("smtp");
transport.connect(host, from, pass);
transport.sendMessage(message, message.getAllRecipients());
transport.close();
} catch (AddressException ae) {
ae.printStackTrace();

return true;

Or Gmail via SSL in which you should add
//change port number
prop.put("mail.smtp.port", "465");
prop.put("mail.smtp.socketFactory.port", "465");
prop.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
Output:
Also you can change BodyPart accordingly i have included an html responsive template
I recommend you to visit your Google Account and generate a new Application Password , this allows your password field to be encoded and not used as plain text
Otherwise you will come up with this exception
javax.mail.AuthenticationFailedException: 534-5.7.9 Application-specific password required.
Hope it helped!

I have an web application in which i am sending mail to user. Following is my code.
String host = "smtp.gmail.com";
String pwd = "123";
String from = "sender#gmail.com";
String to = "receiver#gmail.com";
String subject = "Test";
String messageText = "This is demo mail";
int port = 587;
boolean sessionDebug = false;
Properties props = System.getProperties();
props.put("mail.smtp.starttls.enable","true");
props.put("mail.smtp.host", host);
props.put("mail.smtp.port", port);
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.starttls.required", "true");
java.security.Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider());
Session mailSession = Session.getDefaultInstance(props, null);
mailSession.setDebug(sessionDebug);
Message msg = new MimeMessage(mailSession);
msg.setFrom(new InternetAddress(from));
InternetAddress[] add = {new InternetAddress(to)};
msg.setRecipient(Message.RecipientType.TO, new InternetAddress(to));
msg.setRecipients(Message.RecipientType.TO, add);
msg.setSubject(subject);
msg.setSentDate(new Date());
msg.setText(messageText); //Actual msg
Transport transport = mailSession.getTransport("smtp");
transport.connect(host, from, pwd);
transport.sendMessage(msg, msg.getAllRecipients());
transport.close();
This code is executed on local but fails on server domain. I have search a lot but that solution didn't work for me.
I tried a lot like replacing transport.connect(host, from, pwd); with transport.connect(host, 587, from, pwd); or 465and also String host="smtp.gmail.com"; with static domain IP. but still not working.
can anyone figure out what i am missing..?
Here is working example.
If this didn't work then there must be a problem with your server..

int counter = 0;
for (String obj: recipientList) {
recipientAddress[counter] = new InternetAddress(obj.trim());
counter++;
}
msg.setRecipients(Message.RecipientType.TO, recipientAddress);
} else {
InternetAddress[] recipientAddress = {
new InternetAddress(recipient)
};
msg.setRecipients(Message.RecipientType.TO, recipientAddress);
}
msg.setSubject(subject);
msg.setSentDate(new Date());
// creates message part

}
// sets the multi-part as e-mail's content

I am able to send email successfully. But now I want to send the full body part of the html file. I wrote a method readHTML(), but its not reading the content of that file neither it sends the same. It sends only what I've stored in message variable. Where did I make mistake?
I'm trying to create a program using the JavaMail API, however, I keep getting the following error message.

Thank you!
You're connecting to localhost to send the message. Do you have a mail server running on your local machine? Probably not. You need to set the mail.smtp.host property. You may also need to supply a username and password for your mail server; see the JavaMail FAQ.
The following code may solve your problem
import java.util.*;

String from = USER_NAME;
String pass = PASSWORD;
String[] to = { RECIPIENT }; // list of recipient email addresses
String subject = "Java send mail example";
String body = "hi ....,!";
sendFromGMail(from, pass, to, subject, body);
}
private static void sendFromGMail(String from, String pass, String[] to, String subject, String body) {
Properties props = System.getProperties();

I have just tried to send an email through java code. Actually it works fine with no errors at all.But when i recieve email it does not contain attachment which according to the code should be there("try.txt").
I have no idea at all about JavaMail i just gone through this code and tried this
Code Here

multipart.addBodyPart(messageBodyPart);
//attachment

transport.sendMessage(message, message.getAllRecipients());
transport.close();
}
catch (AddressException ae) {

}
catch (MessagingException me) {

}
}
}
Something special need to be added for an attachment to be sent properly ?
Please guide me.
Thanks in advance
Remove this line from your code
message.setText(body);
setText() internally calls setContent() function. So if you call setText() function after you setContent, it basically over-rides the content you initially set.
See this for more Information.
Try this:
MimeBodyPart mimeBody = new MimeBodyPart();
mimeBody.attachFile(file);
MimeMultipart mimeMulti = new MimeMultipart();
mimeMulti.addBodyPart(mimeBody);
msg.setContent(mimeMulti);
I faced similar challenges sending email with attachments programatically. I used Apache Commons Email like this:
public static final String ATTACHMENT_PATH = "/opt/testfile/example_4mb_file.mp4";
// Create the attachment
File attachFile = new File(ATTACHMENT_PATH);
EmailAttachment attachment = new EmailAttachment();
attachment.setPath(attachFile.getAbsolutePath());
attachment.setDisposition(EmailAttachment.ATTACHMENT);
attachment.setDescription(attachFile.getName());
attachment.setName(attachFile.getName());
// Create the email message
MultiPartEmail email = new MultiPartEmail();
email.setHostName("smtp.gmail.com");
email.setSmtpPort(465);
email.setAuthenticator(new DefaultAuthenticator(
EMAIL_USERNAME,
EMAIL_PASSWORD));
email.setSSLOnConnect(true);
email.addTo(EMAIL_RECEIVER);
email.setFrom(EMAIL_SENDER, EMAIL_SUBJECT);
email.setSubject("TestMail id " + this.uniqueId);
email.setMsg("This is a test attachment mail ... :-)");
// add the attachment
email.attach(attachment);
// send the email
email.send();
