无法使用java mail api发送带有附件的html内容

我想发送html内容以及附件。那么,如何在同一封邮件中发送呢?

有人能给我指路吗。谢谢

try {  

MimeMessage message = new MimeMessage(session);  
            message.setFrom(new InternetAddress(user));  


            message.addRecipient(Message.RecipientType.CC,new InternetAddress("username@abc.com"));
             MimeBodyPart messageBodyPart1 = new MimeBodyPart();  
            messageBodyPart1.setText(data, "text/html");
            MimeBodyPart messageBodyPart2 = new MimeBodyPart();  
            String filename = "Data.xlsx";//change accordingly  
            DataSource source = new FileDataSource(filename);  
            messageBodyPart2.setDataHandler(new DataHandler(source));  
            messageBodyPart2.setFileName(filename);
            Multipart multipart = new MimeMultipart();  
            multipart.addBodyPart(messageBodyPart1);  
            multipart.addBodyPart(messageBodyPart2);  
            message.setSubject("FOS Report");  
            message.setContent(multipart); 

    //send the message  
     Transport.send(message);  

     System.out.println("message sent successfully...");  

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