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。
