struts實現文件上傳

struts中實現文件下載的主要代碼：

public ActionForward execute(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) { String strFileName = "測試文件.rar"; File file = new File("具體路徑" + strFileName);// if(file.exists()){ try{ BufferedInputStream bis = new BufferedInputStream(new FileInputStream(file)); byte[] buffer = new byte[1024]; strFileName = java.net.URLEncoder.encode(strFileName, "UTF-8");//處理中文文件名的問題 strFileName = new String(strFileName.getBytes("UTF-8"),"GBK");//處理中文文件名的問題 response.reset(); response.setCharacterEncoding("UTF-8"); response.setContentType("application/x-rar-compressed");//不同類型的文件對應不同的MIME類型 response.setHeader("Content-Disposition","attachment; filename=" + strFileName); OutputStream os = response.getOutputStream(); while(bis.read(buffer) > 0){ os.write(buffer); } bis.close(); os.close(); } catch(Exception e){ ...... } } return mapping.getInputForward(); }

在Struts中的實現和在ASP.NET的實現類似，這段代碼就是將服務器上的文件以流的方式發送到客戶端瀏覽器，如果要是在線打開的方式的話還應將response.setHeader("Content-Disposition","attachment; filename=" + strFileName);改寫爲response.setHeader("Content-Disposition","inline; filename=" + strFileName);
