我已经从我的笔记本电脑成功使用以下代码,收件人收到了预期的邮件。但是,将代码放在jar中并从托管服务器运行时。我得到以下错误。
的代码 的
Properties props = new Properties();
props.put("mail.smtp.host", "smtp.gmail.com");
props.put("mail.smtp.auth", "true");
props.put("mail.debug", "true");
props.put("mail.smtp.port", 465);
props.put("mail.smtp.socketFactory.port", 465);
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.ssl.enable", "true");
props.put("mail.transport.protocol", "smtp");
Session mailSession = null;
mailSession = Session.getInstance(props,
new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication("emailadress", "password");
}
});
try {
Transport transport = mailSession.getTransport();
MimeMessage message = new MimeMessage(mailSession);
message.setSubject("Todays Email!:");
message.setFrom(new InternetAddress("theemailsender@gmail.com"));
message.addRecipients(Message.RecipientType.TO, InternetAddress.parse("recipient1@gmail.com"));
String body = theBody;
message.setContent(body,"text/html");
transport.connect();
transport.sendMessage(message,message.getAllRecipients());
transport.close();
} catch (Exception exception) {
}
错误 的
DEBUG SMTP: Found extension "SIZE", arg "35882577"
DEBUG SMTP: Found extension "8BITMIME", arg ""
DEBUG SMTP: Found extension "AUTH", arg "LOGIN PLAIN XOAUTH XOAUTH2 PLAIN-CLIENTTOKEN"
DEBUG SMTP: Found extension "ENHANCEDSTATUSCODES", arg ""
DEBUG SMTP: Found extension "CHUNKING", arg ""
DEBUG SMTP: STARTTLS requested but already using SSL
DEBUG SMTP: Attempt to authenticate using mechanisms: LOGIN PLAIN DIGEST-MD5 NTLM
DEBUG SMTP: AUTH LOGIN command trace suppressed
DEBUG SMTP: AUTH LOGIN failed
我在这一点上假设我要么将startle.enable或ssl.enable设置为true,而不是两者都设置为true。

这段代码对我有用,如果有帮助的话。您可以删除与附件相关的部分。
public static void sendEmailWithAttachments(String host, String port, final String userName,
final String password, String toAddress, String subject, String message,
String[] attachFiles)
throws AddressException, MessagingException {
// sets SMTP server properties
Properties properties = new Properties();
properties.put("mail.smtp.host", host);
properties.put("mail.smtp.port", port);
properties.put("mail.smtp.auth", "true");
properties.put("mail.smtp.starttls.enable", "true");
properties.put("mail.user", userName);
properties.put("mail.password", password);
// creates a new session with an authenticator
Authenticator auth = new Authenticator() {
public PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(userName, password);
}
};
Session session = Session.getInstance(properties, auth);
// creates a new e-mail message
Message msg = new MimeMessage(session);
msg.setFrom(new InternetAddress(userName));
InternetAddress[] toAddresses = { new InternetAddress(toAddress) };
msg.setRecipients(Message.RecipientType.TO, toAddresses);
msg.setSubject(subject);
msg.setSentDate(new Date());
// creates message part
MimeBodyPart messageBodyPart = new MimeBodyPart();
messageBodyPart.setContent(message, "text/html");
// creates multi-part
Multipart multipart = new MimeMultipart();
multipart.addBodyPart(messageBodyPart);
// adds attachments
if (attachFiles != null && attachFiles.length > 0) {
for (String filePath : attachFiles) {
MimeBodyPart attachPart = new MimeBodyPart();
try {
attachPart.attachFile(filePath);
} catch (IOException ex) {
ex.printStackTrace();
}
multipart.addBodyPart(attachPart);
}
}
// sets the multi-part as e-mail's content
msg.setContent(multipart);
// sends the e-mail
Transport.send(msg);
}
在安全模式下,您可能需要将端口465替换为587。
