2. 简单的servlet上传文件处理// 上传之后的文件保存在这个文件夹下String filepath = this.getServletContext().getRealPath("")+java.io.File.separator+"picture"+java.io.File.separator;String filename = "";String type="";ServletInputStream in = request.getInputStream();byte[] buf = new byte[4048];int len = in.readLine(buf, 0, buf.length);String f = new String(buf, 0, len - 1); while ((len = in.readLine(buf, 0, buf.length)) != -1) {filename = new String(buf, 0, len); int j = filename.lastIndexOf("""); int p = filename.lastIndexOf("."); //文件类型 type=filename.substring(p,j); //文件名称 filename = System.currentTimeMillis()+type; DataOutputStream fileStream = new DataOutputStream(new BufferedOutputStream(new FileOutputStream(filepath+ filename)) ); len = in.readLine(buf, 0, buf.length); len = in.readLine(buf, 0, buf.length); while ((len = in.readLine(buf, 0, buf.length)) != -1) { String tempf = new String(buf, 0, len - 1); if (tempf.equals(f) || tempf.equals(f + "--")) { break; } else{ // 写入 fileStream.write(buf, 0, len); } } fileStream.close();}PrintWriter out=response.getWriter();String result = filename ;out.print(result);out.close();in.close();??

1 楼 llshxy 2011-09-14 很不错，下载后需要改web.xml中的servlet路径。O(∩_∩)O谢谢
