1. MIME�c�d��的设�|�： <br />
Web ���览器���?MIME �c�d��来识别非 HTML 文档�Q��ƈ军_��如何昄���该文���内的数据�?<br />
例如EXCEL文�g�?MIME �c�d���?"application/vnd.ms-excel "。要用servlet 来打开一�?EXCEL 文档�Q�需要将 response 对象�?header �?contentType 讄����?#8220;application/vnd.ms-excel &#8221;�?<br />
response.setContentType(contentType); <br />
<br />
2. Content disposition <br />
HTTP response header中的content-disposition 允许 servlet 指定文���表示的信息。��用这�U�header �Q�你���可以将文���指定成单独打开�Q�而不是在���览器中打开�Q�，�q�可以根据用��L��操作来显�C��?<br />
如果用户要保存文���，你还可以�����文��������一个文件名。这个徏议名�U�C��出现�?Save As 对话框的&#8220;文�g�?#8221;栏中。如果没有指定，则对话框中就会出�?servlet 的名字�?<br />
servlet 中，��?header 讄���成下面这��P�� <br />
response.setHeader("Content-disposition","attachment;filename="+ "Example.xls" ); <br />
<br />
response.setHeader("Content-Disposition", "inline; filename="fliename) <br />
点击打开会在ie中打开�?<br />
<br />
<br />
需要说明的有三点： <br />
&#216; 中文文�g名需要进行iso8859-1转码方可正确昄����Q?<br />
fileName = new String(fileName.getBytes("GBK"),"iso8859-1"); <br />
&#216; 传递的文�g名，需要包含后�~�名（如果此文件有后缀名）�Q�否则丢失文件的属性，而不能自行选择相关�E�序打开�?<br />
&#216; 有下载前询问�Q�是打开文�g�q�是保存到计���机�Q�和通过IE���览器直接选择相关应用�E�序插�g打开两种方式�Q�前者如上代码所�C�，后者如下： <br />
response.setHeader("Content-disposition","filename="+ "Example.xls" ); <br />
3. 在研�I�文件的上传及下载过�E�中�Q�有几点体会 <br />
�E�序的I/O操作往往是性能的瓶颈所在，java io定义了两个基本的抽象�c?InputStream和OutputStream,对于不同的数据类型比如磁盘，�|�络又提供了不同的实玎ͼ�java.io也提供了一些缓冲流(BufferedStream)�Q��ɼ��盘可以很快的读写一大块的数�? 而Java基本的I/O�c�M���ơ只能读写一个字�?但缓冲流(BufferedStream)可以一�ơ读写一�Ҏ��据，,�~�冲��?Buffered Stream)大大提高了I/O的性能。所�? <br />
&#216;���块���块的读写数据会非常�?因此,���量大块的读写数�?<br />
&#216;使用BufferedInputStream和BufferedOutputStream来批处理数据以提高性能 <br />
&#216;对象的序列化(serialization)非常影响I/O的性能,���量���用 </div>
