下载某一封邮件中的指定附件

3个知识点：

1：需要通过NoteID来定位该邮件：

Database dbMail = sNotes.getDatabase(sNotes.getServerName(), 
                      mailfile, false);
Document doc = dbMail.getDocumentByID(noteid);

2：其次需要通过attachment name来定位该附件：

EmbeddedObject eAttach = 
(EmbeddedObject)doc.getAttachment(attachmentFileName);

3：通过EmbeddedObject的extractFile方法下载附件。

代码片段：



Database dbMail = sNotes.getDatabase(sNotes.getServerName(), 


                      mailfile, false);


Document doc = dbMail.getDocumentByID(noteid);


if (doc != null) 


{


       // Given the name of a file attachment, returns a NotesEmbeddedObject 


       // representing the attachment. You can use this method to find file 


       // attachments which are not contained in a rich text item 


       // (such as an attachment in a Release 2 database), 


       // as well as file attachments that are contained in a rich text item.


       EmbeddedObject eAttach = 


       (EmbeddedObject)doc.getAttachment(attachmentFileName);


       // 查看附件


       if(eAttach != null)


       {


          logger.info("打开了指定邮件的指定附件");


       


          // 是否是我们要寻找的哪个附件？


          // 是的话，就保存下来


          String strAttachmentFileName = 


                 eAttach.getSource();


       


          // Writes a file attachment to storag


          if(strAttachmentFileName.length() > 0)


                 eAttach.extractFile("c:\\" + strAttachmentFileName);


                 


          eAttach.recycle();


        }


}



 

这其中的attachmentFileName参数是通过EmbeddedObject的getName方法拿到的：

// getName returns a String value containing the name 
// used to reference an object that was embedded programmatically.
String strAttachmentObjectName = 
   eAttach.getName();

而不是通过getSource()拿到的。当一封邮件中同时存在多个重名附件时，getName()和getSource()就不一样了。
