springle mvc中如何下載下傳檔案呢?
比struts2 下載下傳檔案簡單得多
先看例子:
@responsebody
@requestmapping(value = "/download",produces="application/octet-stream")
public byte[] downloadfile(httpservletrequest request, httpservletresponse response,string contenttype2)
throws ioexception {
byte[]bytes=fileutils.getbytes4file("d:\\temp\\cc.jpg");
response.addheader("content-disposition", "inline;filename=\"a.jpg\"");
return bytes;
}
在浏覽器中通路:http://localhost:8080/tv_mobile/video/download
注意:
(1)使用注解@responsebody 表示action傳回的内容直接作為應答體傳回;
(2)通過produces 設定傳回的content type;
(3)直接傳回要下載下傳的檔案的二進制數組
