我是 Java Mail 的新手。當(dāng)我執(zhí)行下面的代碼時(shí)，我遇到了一個(gè)異常javax.mail.MessagingException：無法向 SMTP 主機(jī)發(fā)送命令public void sendMessage(EmailMessage emailMessage) throws MessagingException { Properties props = new Properties(); props.put("mail.smtp.auth", "true"); props.put("mail.smtp.starttls.enable", "true"); props.put("mail.smtp.host", "smtp.gmail.com"); props.put("mail.smtp.port", "587"); System.out.println(emailMessage.getFromAddress()); Optional<EmailId> emailIdOptional = emailIdRepository.findByEmailId(emailMessage.getFromAddress()); System.out.println(emailIdOptional.get().getEmailId()); Session session = Session.getInstance(props, new javax.mail.Authenticator() { protected PasswordAuthentication getPasswordAuthentication() { return new PasswordAuthentication(emailIdOptional.get().getEmailId(), emailIdOptional.get().getPassword()); } }); javax.mail.Message msg = new MimeMessage(session); msg.setFrom(new InternetAddress(emailMessage.getFromAddress(), false)); msg.setRecipients(javax.mail.Message.RecipientType.TO, InternetAddress.parse(emailMessage.getToAddress())); msg.setSubject(emailMessage.getSubject()); msg.setContent(emailMessage.getMessage(), "text/html"); msg.setSentDate(new Date()); MimeBodyPart messageBodyPart = new MimeBodyPart(); messageBodyPart.setContent(emailMessage.getMessage(), "text/html"); Transport.send(msg);}任何人都請幫我解決這個(gè)問題。

String host = "smtp.xyz.com";
final String username = "xyz@business.com";
final String password = "your password";
Properties props = new Properties();
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.starttls.enable", "true");
// go to account setting -> smtp setting and get server name and port
props.put("mail.smtp.host", "your server name");
props.put("mail.smtp.port", "your server port");
props.put("mail.debug", "true");
try {
Session session = Session.getInstance(prop,
new javax.mail.Authenticator() {
protected javax.mail.PasswordAuthentication getPasswordAuthentication() {
return new javax.mail.PasswordAuthentication(username, password);
}
});
Message msg = new MimeMessage(session);
msg.setFrom(new InternetAddress("xyz@business.com"));
msg.setRecipients(Message.RecipientType.TO,
InternetAddress.parse("abc@business.com"));
msg.setSubject("Test E-Mail through Java");
Transport.send(msg,username,password);
System.out.println("Sent message successfully...");
}catch(Exception e){
}
你可以試試這個(gè)可能會(huì)解決你的問題！?。?！

此代碼對我有用：-
public static void SendMessage(final String femail, final String fpass, final String email, final String subject, final String message)
{
//Creating properties
Properties props = new Properties();
//Configuring properties for gmail
//If you are not using gmail you may need to change the values
props.put("mail.smtp.host", "smtp.gmail.com");
props.put("mail.smtp.port", "587");
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.ssl.trust", "smtp.gmail.com");
//Creating a new session
Session session = Session.getDefaultInstance(props,
new javax.mail.Authenticator() {
//Authenticating the password
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(femail, fpass);
}
});
try {
//Creating MimeMessage object
MimeMessage mm = new MimeMessage(session);
//Setting sender address
mm.setFrom(new InternetAddress(femail));
//Adding receiver
mm.addRecipient(Message.RecipientType.TO, new InternetAddress(email));
//Adding subject
mm.setSubject(subject);
//Adding message
mm.setText(message);
//Sending email
Transport.send(mm);
} catch (MessagingException e) {
e.printStackTrace();
}
}
我已經(jīng)編輯了代碼并使用 starttls 方法進(jìn)行了設(shè)置。
希望會(huì)有所幫助?。。?！
