Answer 1

//response.setHeader("Content-disposition","inline;filename="+displayName);
此行代码已经改为
response.setHeader("Content-Disposition","attachment;filename="+displayName);
有没有专家指导下。
百度上能找到的答案基本都试过求专家级别指导啊。

Answer 2

欢迎想了解java下载问题的同志前来顶帖。。
不顶就又沉了。

Answer 3

response.reset();
response.setContentType("application/octet-stream;charset=GBK");
response.setHeader("Content-Disposition", "attachment; filename=\"" + new String(displayName.getBytes("GBK"), "ISO-8859-1") + "\"");
attachment是下载,inline是在线打开

Answer 4

你改成
response.setHeader("Content-Disposition","attachment;filename="+displayName);这样还不对，我不信。
重新发布了吗？？下面这样写，试试看。 其实我觉得不改也没关系。response.setContentType("application/vnd.ms-excel");
还有你怎么没有往
response.getOutputStream()里写东西呀

Answer 5

response.setContentType("text/csv;charset=UTF-8"); response.setHeader("Content-Disposition", "attachment;filename=" + file);我就这两行就可以下载了

Answer 6

<mime-mapping>
  <extension>csv</extension>
  <mime-type>application/oct-stream</mime-type>
 </mime-mapping>终于找出问题了。Tomcat/conf/web.xml 文件中缺少了以上代码。发出来这个答案，希望对看到的人有用。谢谢上面回答的人。。
