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EmbeddedObjectextractFile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EmbeddedObjectgetName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()getSource()就不一样了。
