通過Domino Java代理,我使用Apache POI來生成Excel電子表格。代碼首先將文件保存到驅動器;我已驗證我可以在那裏打開文件,並且該文件包含信息。但是,當我通過MIME將其附加到電子郵件中時,我收到一條消息,指出「Excel無法打開文件spreadsheet.xlxs」和「文件格式或文件擴展名無效」。無法打開流式文件附件
下面是我使用的代碼:
MIMEEntity ebody = maildoc.createMIMEEntity();
Stream outStream = session.createStream();
Stream inStream = session.createStream();
inStream.open(entry.getValue(),"binary");
do {
byte[] buffer = inStream.read(32767);
outStream.write(buffer);
} while(!inStream.isEOS());
inStream.close();
MIMEEntity child = ebody.createChildEntity();
child.setContentFromBytes(outStream, "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet", MIMEEntity.ENC_IDENTITY_BINARY);
MIMEHeader cdHeader = child.createHeader("Content-Disposition");
cdHeader.setHeaderVal("attachment; filename="spreadsheet.xlxs");
MIMEHeader idHeader = child.createHeader("Content-ID");
idHeader.setHeaderVal("spreadsheet.xlxs");
outStream.truncate();
outStream.close();
任何想法,我在哪裏呢?
