Java电子邮件内容为空

Question

我有代码段，我在其中发送带有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都可以正常工作。唯一没有出现的是电子邮件内容。我已经测试了我的电子邮件以不是空的。我还能做什么才能使它出现？我什至已经启用了这条代码smagebodyPart.setText（emailContent）;却一样。但是，如果启用了此部分Multipart1.AddBodyPart（emailContent）;我有错误

 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("nnSend email :"+eMArray[0]);
     transport.sendMessage(emailMessage, emailMessage.getAllRecipients());

}
catch (Exception e) 
{
System.out.println("Transport Problem");
e.printStackTrace();
}

您已经初始化

BodyPart messageBodyPart = new MimeBodyPart();

两次。在第二个初始化之前，您要添加身体内容。因此，删除行

messageBodyPart = new MimeBodyPary();

行，它可以正常工作。

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("nnSend email :"+eMArray[0]);
        transport.sendMessage(emailMessage, emailMessage.getAllRecipients());
