有没有一种通用的方法可以在jsp中下载所有类型的文件？

好的，从其他浏览器下载文件时会出现一些问题。我的示例照顾了MSIE和Mozilla类型的浏览器中所需的处理

public HttpServletResponse getFile (HttpServletRequest request ,HttpServletResponse httpServletResponse, .......){          HttpServletResponse response = httpServletResponse;          InputStream in =          String filename = "";          String agent = request.getHeader("USER-AGENT");          if (agent != null && agent.indexOf("MSIE") != -1)          { filename = URLEnprer.enpre(, "UTF8"); response.setContentType("application/x-download"); response.setHeader("Content-Disposition","attachment;filename=" + filename);          }          else if ( agent != null && agent.indexOf("Mozilla") != -1)          { response.setCharacterEncoding("UTF-8"); filename = MimeUtility.enpreText(, "UTF8", "B"); response.setContentType("application/force-download"); response.addHeader("Content-Disposition", "attachment; filename="" + filename + """);          }          BufferedOutputStream out = new BufferedOutputStream(response.getOutputStream());          byte by[] = new byte[32768];          int index = in.read(by, 0, 32768);          while (index != -1) {   out.write(by, 0, index);   index = in.read(by, 0, 32768);          }          out.flush();          return response;}

看一下这个
