从java web应用程序发送邮件

java email

从java web应用程序发送邮件,java,email,jakarta-mail,Java,Email,Jakarta Mail,我正在开发一个可以发送电子邮件的web应用程序。我正在使用javax邮件api。我能够从测试用例中发送主题、发件人姓名和内容的电子邮件。但当应用程序运行时，它会发送不带主题的消息，内容如下所示 ------=_Part_3_47905596.1416462380132 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: 7bit Test mail Send Succesfully ------=_Part_3_

这是我正在使用的代码

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");
String subject = "Test Subject";
String msgContent = "Test mail Send Succesfully";
String senderName = "Jos";
String password = "XXXXXXXXXXX";
String fromEmail = "xxxxxxxxx@gmail.com";
String toEmail = "YYYYYYYYYYY@gmail.com";
Session session = Session.getInstance(props,
            new javax.mail.Authenticator() {
                protected PasswordAuthentication getPasswordAuthentication() {
                    return new PasswordAuthentication(fromEmail, password);
                }
            });
Message message = new MimeMessage(session);
MimeBodyPart textPart = new MimeBodyPart();
textPart.setText(msgContent, "utf-8");
Multipart multiPart = new MimeMultipart("alternative");
multiPart.addBodyPart(textPart);
message.setContent(multiPart);
message.setFrom(new InternetAddress(fromEmail, senderName));
message.setRecipients(Message.RecipientType.TO,
            InternetAddress.parse(toEmail));
message.setSubject(subject);
message.setSentDate(new Date());
Transport.send(message);
添加了调试消息，但未使用多部分
