我想創建一個程序，發送一個電子郵件包含某些數據與附件，但由於某種原因電子郵件中的文本沒有收到。整個代碼爲：Javamail電子郵件與attatchment：文本沒有被髮送

message.setFrom(new InternetAddress("[email protected]"));
message.setRecipients(Message.RecipientType.TO,
InternetAddress.parse("[email protected]"));
message.setSubject("Application 'Bitter Coffee' Has Been Activated By " + hostname);
message.setText("This is the body text that won't show up");
MimeBodyPart messageBodyPart = new MimeBodyPart();
Multipart multipart = new MimeMultipart();
messageBodyPart = new MimeBodyPart();
String file = "errorcapture.png";
String fileName = "errorcapture.png";
DataSource source = new FileDataSource(file);
messageBodyPart.setDataHandler(new DataHandler(source));
messageBodyPart.setFileName(fileName);
multipart.addBodyPart(messageBodyPart);
message.setContent(multipart);
System.out.println("Sending");
Transport.send(message);
System.out.println("Done");
} catch (MessagingException e) {
e.printStackTrace();
}
}
請解釋一下徹底的，因爲我在Java的一個完整的小白。 感謝您的幫助！ :) 也告訴我，如果我錯過任何帖子，因爲這只是我的第二或第三S.O.問題
你是什麼意思？我將其基於免責聲明中列出的項目，但我自己創建了該項目。我是銀牌。我已經按照您的建議檢查了Javamail FAQ，但沒有找到解決我的問題的方法。任何想法如何添加一個部分？ – Silver
請參閱上面引用的下載中的sendfile.java示例程序。當您調用msg.setText時，您將消息的全部內容設置爲文本。稍後調用msg.setContent時，將使用多部分內容替換消息的全部內容。但是你的多部分內容只有一個部分 - 附件。它還需要爲消息的主體內容添加一部分。 –
啊謝謝！這就是訣竅！ – Silver
