Question

收到错误“方法尚未实现 mimemessage”

尝试发送电子邮件时

   protected static void addAtachments(String[] attachments, Multipart multipart) throws MessagingException, MessagingException {

    for (int i = 0; i <= attachments.length - 1; i++) {
    String filename = attachments[i];
    MimeBodyPart attachmentBodyPart = new MimeBodyPart();

    DataSource source = new FileDataSource(filename);
    attachmentBodyPart.setDataHandler(new DataHandler(source));

    attachmentBodyPart.setFileName(filename);
    multipart.addBodyPart(attachmentBodyPart);
}}



  protected static void sendMessage(List<String> recipients, String subject,
                              String messageContent, String from, String[] attachments)
    throws MessagingException, MessagingException {
boolean debug = false;

Properties props = new Properties();
props.put("mail.smtp.host", SMTP_HOST_NAME);
props.put("mail.smtp.auth", "true");
props.put("mail.debug", "true");
props.put("mail.smtp.port", SMTP_PORT);
props.put("mail.smtp.socketFactory.port", SMTP_PORT);
props.put("mail.smtp.socketFactory.fallback", "false");

Session session = Session.getDefaultInstance(props,
        new Authenticator() {

                return new PasswordAuthentication("xxxxx", "xxxxxx");
            }
        });

session.setDebug(debug);

Message message = new MimeMessage(session);
InternetAddress addressFrom = new InternetAddress(from);
message.setFrom(addressFrom);

for (String recipient : recipients) {
    message.addRecipient(Message.RecipientType.TO,
            new InternetAddress(recipient));
}

multipart.addBodyPart(messageBodyPart);
addAtachments(attachments, multipart);

message.setContent(multipart);
Transport.send(message);}

Answer 1

请确保java邮件依赖项如下 1、

<dependency>
    <groupId>javax.mail</groupId>
    <artifactId>mail</artifactId>
    <version>1.4.7</version>`
</dependency>

因为还有另一个jar包含javax.mail.* 包裹在下面 2、

<dependency>
    <groupId>geronimo-spec</groupId>
    <artifactId>geronimo-spec-j2ee</artifactId>
    <version>1.4-rc4</version>`
</dependency>

解决方案是将第二个依赖项替换为第一个依赖项
