Question

我有代码片段，我发送带excel文件附件的电子邮件。一切正常，我可以看到标题甚至文件附件。唯一没有出现的是电子邮件内容。我测试过我的emailContent变量不为空。我还能做些什么才能让它出现？我甚至启用了这行代码messageBodyPart.setText（emailContent）;但是一样的。但如果启用此部分multipart1.addBodyPart（emailContent）;我收到错误

 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();
}

您已初始化

BodyPart messageBodyPart = new MimeBodyPart();

两次。在第二次初始化之前，您需要添加正文内容。所以删除行

messageBodyPart = new MimeBodyPary();

Line，它会正常工作。

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());

Java电子邮件内容为空
