Answer 1

该法典的工作

String host = "smtp.gmail.com";
user="youEmail@gmail.com";
pass="yourPassword";

 String SSL_FACTORY = "javax.net.ssl.SSLSocketFactory";
String to = email_to_address; // out going email id
String from = email_from_address; //Email id of the recipient
String subject = email_subject;
String messageText = email_body;
boolean sessionDebug = true;


Properties props = System.getProperties();
props.put("mail.host", host);
props.put("mail.transport.protocol.", "smtp");
props.put("mail.smtp.auth", "true");
 props.put("mail.smtp.", "true");
props.put("mail.smtp.port", "465");
props.put("mail.smtp.socketFactory.fallback", "false");
props.put("mail.smtp.socketFactory.class", SSL_FACTORY);


 Session mailSession = Session.getDefaultInstance(props, null);
 mailSession.setDebug(sessionDebug);


 Message msg = new MimeMessage(mailSession);
 msg.setFrom(new InternetAddress(from));
 InternetAddress[] address = {new InternetAddress(to)};
 msg.setRecipients(Message.RecipientType.TO, address);
 msg.setSubject(subject);
 msg.setContent(messageText, "text/html"); // use setText if you want to send text


Transport transport = mailSession.getTransport("smtp");
transport.connect(host, user, pass);


try {
transport.sendMessage(msg, msg.getAllRecipients());
out.println("Send Success");
WasEmailSent = true; // assume it was sent
}

catch (Exception err) {
WasEmailSent = false; // assume it s a fail
}
transport.close();

Answer 2

尝试你的法典中的词汇

Properties = new Properties();
props.put("mail.smtp.host", host);
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.port", "465");
props.put("mail.smtp.socketFactory.port", "465");
props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");

together with these you also need to pass the authenticator to the Session.getDefaultInstance

喜欢

Session mailSession = Session.getDefaultInstance(props, {pass authenticator here});
