包路径：javax.mail.internet.MimeBodyPart
类名称：MimeBodyPart
方法名：setDataHandler

MimeBodyPart.setDataHandler介绍

[英]This method provides the mechanism to set this body part's content. The given DataHandler object should wrap the actual content.
[中]此方法提供了设置此主体部分内容的机制。给定的DataHandler对象应该包装实际内容。

  1. if (arrayInputStream != null && arrayInputStream instanceof ByteArrayInputStream) {
  2.    // create the second message part with the attachment from a OutputStrean
  3.    MimeBodyPart attachment= new MimeBodyPart();
  4.    ByteArrayDataSource ds = new ByteArrayDataSource(arrayInputStream, "application/pdf"); 
  5.    attachment.setDataHandler(new DataHandler(ds));
  6.    attachment.setFileName("Report.pdf");
  7.    mimeMultipart.addBodyPart(attachment);
  8.  }
