[英]JavaMail mail and attachment
我正在嘗試使用JavaMail發送帶有html文本和附件的電子郵件。 但是,我似乎只能一次完成一項工作,要么發送html文本,要么發送附件,但不能兩者都行,我不知道如何使兩者都行。
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");
final String username = "email@gmail.com";
final String password = "**********************";
Session session = Session.getInstance(props,
new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(username, password);}});
try {
Message message = new MimeMessage(session);
message.setFrom(new InternetAddress("email@gmail.com"));
message.setRecipients(Message.RecipientType.TO,
InternetAddress.parse("email to send"));
message.setSubject("Testing Subject");
MimeBodyPart messageBodyPart = new MimeBodyPart();
Multipart multipart = new MimeMultipart();
messageBodyPart = new MimeBodyPart();
// Attachment
String file = "/Users/user/Desktop/file.rtf";
String fileName = "file.rtf";
DataSource source = new FileDataSource(file);
messageBodyPart.setDataHandler(new DataHandler(source));
messageBodyPart.setFileName(fileName);
multipart.addBodyPart(messageBodyPart);
message.setContent("<h1>HTML Text</h1>",
"text/html");
//HTML Text
message.setContent(multipart); //attachment
//Send
System.out.println("Sending");
Transport.send(message);
System.out.println("Done");
} catch (MessagingException e)
{
e.printStackTrace();
throw new RuntimeException(e);
}
這是我最近從事的項目的工作代碼。 希望能幫助到你!
String from = "JohnDoe@gmail.com";
String pass = "***********";
String[] to = { "JohnDoe@gmail.com" }; // list of recipient email addresses
String subject = "Subject Line";
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]);
}
BodyPart messageBodyPart = new MimeBodyPart();
// Now set the actual message
messageBodyPart.setText("");
// Create a multipar message
Multipart multipart = new MimeMultipart();
// Set text message part
multipart.addBodyPart(messageBodyPart);
// Part two is attachment
messageBodyPart = new MimeBodyPart();
String filename = "send.jpeg";
DataSource source = new FileDataSource(filename);
messageBodyPart.setDataHandler(new DataHandler(source));
messageBodyPart.setFileName(filename);
multipart.addBodyPart(messageBodyPart);
message.setContent(multipart);
message.setSubject(subject);
Transport transport = session.getTransport("smtp");
transport.connect(host, from, pass);
transport.sendMessage(message, message.getAllRecipients());
transport.close();
}
catch (AddressException ae) {
ae.printStackTrace();
}
catch (MessagingException me) {
me.printStackTrace();
}
您兩次調用message.setContent。 第二個呼叫將覆蓋第一個呼叫,替換內容。
