Action层:
public String myDownloadFile() {
HttpServletResponse response = ServletActionContext.getResponse();
String myFileName = getFilename(); //设置文件名 一般带有扩展名。是下载后文件的名称。
try {
byte[] buffer = XXXService.readFile(attId); // byte[] 通过id获取文件的byte数组
// 清空response
response.reset();
// 设置response的Header
response.addHeader("Content-Disposition",
"attachment;filename=" + new String(myFileName.getBytes("gb2312"), "ISO8859-1"));
OutputStream toClient = new BufferedOutputStream(response.getOutputStream());
response.setContentType("application/octet-stream");
toClient.write(buffer);
toClient.flush();
toClient.close();
} catch (IOException ex) {
ex.printStackTrace();
}
return null;
}
