我有一段代码，用于发送带有excel文件附件的电子邮件。在我可以看到标题甚至文件附件的地方，一切正常。唯一没有出现的是电子邮件内容。我已经测试过我的emailContent变量不为空。我还能做些什么使它出现？我什至启用了这行代码messageBodyPart.setText（emailContent）;还是一样。 但如果启用，则此部分multipart1.addBodyPart（emailContent）;我收到错误

I have snippet of codes where I send out email with excel file attachment. All works fine where I can see title and even the file attachment. The only thing does not appear is the email content. I have tested that my emailContent variable is not empty. What else can I do to make it appear ? I have even enabled this line of codes messageBodyPart.setText(emailContent); yet the same. But if enabled this part multipart1.addBodyPart(emailContent); I get error

error: no suitable method found for addBodyPart(String) multipart1.addBodyPart(emailContent); try { Message emailMessage = new MimeMessage(mailSession); emailMessage.setFrom(new InternetAddress(origin1)); emailMessage.addRecipient(Message.RecipientType.TO,new InternetAddress(receiptnt1)); emailMessage.addRecipient(Message.RecipientType.TO,new InternetAddress(receiptnt2)); emailMessage.setRecipients(Message.RecipientType.CC,InternetAddress.parse(cc1)); emailMessage.setSubject(emailTitle); emailMessage.setText(emailContent); BodyPart messageBodyPart = new MimeBodyPart(); // Fill the message //messageBodyPart.setText(emailContent);*/ Multipart multipart1 = new MimeMultipart(); // Part two is attachment messageBodyPart = new MimeBodyPart(); DataSource source = new FileDataSource(filename); messageBodyPart.setDataHandler(new DataHandler(source)); messageBodyPart.setFileName(filename); multipart1.addBodyPart(messageBodyPart); // Put parts in message emailMessage.setContent(multipart1); //System.out.println("\n\nSend email :"+eMArray[0]); transport.sendMessage(emailMessage, emailMessage.getAllRecipients()); } catch (Exception e) { System.out.println("Transport Problem"); e.printStackTrace(); }

推荐答案

您已初始化

BodyPart messageBodyPart = new MimeBodyPart();

两次。在第二次初始化之前，您要添加主体内容。 因此删除该行

Two times. And before the second initialization you're adding the body contents. So remove the line

messageBodyPart = new MimeBodyPary();

行，它将正常工作。

使用以下代码。

Message emailMessage = new MimeMessage(mailSession); emailMessage.setFrom(new InternetAddress(origin1)); emailMessage.addRecipient(Message.RecipientType.TO, new InternetAddress(receiptnt1)); emailMessage.addRecipient(Message.RecipientType.TO, new InternetAddress(receiptnt2)); emailMessage.setRecipients(Message.RecipientType.CC, InternetAddress.parse(cc1)); emailMessage.setSubject(emailTitle); // emailMessage.setText(emailContent); Multipart multipart1 = new MimeMultipart(); BodyPart messageBodyPart = new MimeBodyPart(); // Fill the message messageBodyPart.setText(emailContent); // Part two is attachment BodyPart attachment = new MimeBodyPart(); DataSource source = new FileDataSource(filename); attachment.setDataHandler(new DataHandler(source)); attachment.setFileName(filename); multipart1.addBodyPart(attachment); multipart1.addBodyPart(messageBodyPart); // Put parts in message emailMessage.setContent(multipart1); //System.out.println("\n\nSend email :"+eMArray[0]); transport.sendMessage(emailMessage, emailMessage.getAllRecipients());
