Question

我正在编写一个Java方法来发送带有附件的电子邮件。

我要将目标/结果文件夹中的文件附加到电子邮件。我无法附加电子邮件以下是我到目前为止的内容：

public static void sendEmail() {
    String to = "xyz@xyz.com";
    String from = to;
    String host = "mail.xyz.com";

    String linkToLatestTest = getLink();

    // Get the session object
    Properties properties = System.getProperties();
    properties.setProperty("mail.smtp.host", host);
    Session session = Session.getDefaultInstance(properties);

    // compose the message
    try {
        MimeMessage message = new MimeMessage(session);
        message.setFrom(new InternetAddress(from));
        message.addRecipient(Message.RecipientType.TO, new InternetAddress(
                to));
        message.setSubject("Test results from today");
        MimeBodyPart messageBodyPart = new MimeBodyPart();
        messageBodyPart
                .setText("Hello,\nThis is an email regarding latest test");
        Multipart multipart = new MimeMultipart();
        multipart.addBodyPart(messageBodyPart);
        messageBodyPart = new MimeBodyPart();
        String filename = "target/results";
        DataSource source = new FileDataSource(filename);
        messageBodyPart.setDataHandler(new DataHandler(source));
        messageBodyPart.setFileName(filename);
        multipart.addBodyPart(messageBodyPart);

        message.setContent(multipart);
        // Send message
        Transport.send(message);
        System.out.println("message sent successfully....");

    } catch (MessagingException mex) {
        mex.printStackTrace();
    }
}

这是我得到的错误：

任何线索都将有所帮助。预先感谢。

Answer 1

target \ results看起来像是作为目标的目录，并且您正在尝试创建一个名为result的文件，该文件在该目录中没有扩展名。更好的是，您可以按照以下步骤进行操作

/\[[A-Z]+-\d\]/

并确保文件所在的目录具有正确的访问权限
