springmvc照片上传功能
刚从ruby转做java,分个活做照片上传,开始感觉很崩溃,以为本人菜鸟一个,一见到流什么的就感觉很牛逼的东西我怎么会啊,自学加百度,做出来了,两种方法完成,关于js预览就不上传了,留作以后备用,也能帮助下和我一样的菜鸟
jsp页面
<form action="uploadPhoto.do" method="post" enctype="multipart/form-data"> 上传照片:<input type=file name="file" id="file" onchange="javascript:upload();"> <p><div id="localImag"><img id="preview" width=-1 height=-1 style="diplay:none" /></div></p> <img id="imagep" style="display:none" src=http://www.mamicode.com/‘#/‘" /<%=realPath%>" width="300px;" height="350px;"/><br/> <input type="image" src="http://www.mamicode.com/content/template/images/btn_upto2.jpg"> //上传按钮 </form>
/** * 照片上传 * @author sixd * @throws IOException * @throws ServletException * */ @RequestMapping(value = "/uploadPhoto.do") public void uploadPhoto(@RequestParam(value = "file", required = false) MultipartFile file, HttpServletRequest request,HttpServletResponse response) throws Exception { InputStream is = null; OutputStream os = null; List<Map<String,Object>> zplist = null; String responseText = ""; String changName = ""; String realPath = ""; //String uuid = (String) request.getSession().getAttribute("uuid"); //String xhgh = (String) request.getSession().getAttribute("xhgh"); //String uuid = "10020"; String uuid = "10017"; String xhgh = "10017"; String path = request.getSession().getServletContext().getRealPath("drzp"); String fileName = file.getOriginalFilename(); try { zplist = zpscDao.findZpInfo(uuid); int index = fileName.lastIndexOf("."); String endFlag = fileName.substring(index); changName = xhgh.concat(endFlag); System.out.println(path); is = file.getInputStream(); os = new FileOutputStream(path+"\\"+changName); int len = 0; byte[] bytes = new byte[1024]; while((len = is.read(bytes))>0){ os.write(bytes, 0, len); } realPath = "drzp/"+changName+""; if(zplist != null && !zplist.isEmpty()){ zpscDao.updatePhotoPath(realPath,uuid); }else{ zpscDao.savePhotoPath(uuid,xhgh,realPath); } responseText="success"; } catch (Exception e) { log.error(e.getMessage()); e.printStackTrace(); responseText="fail"; }finally{ is.close(); os.close(); } response.sendRedirect("content/template/zpsc/zpsc.jsp?path="+realPath+"&responseText="+responseText+""); }
方法二、
/** * 上传照片 * @author sixd * @throws IOException * @throws ServletException * */ @RequestMapping(value = "/uploadPhoto.do") public void uploadPhoto(@RequestParam(value = "file", required = false) MultipartFile file, HttpServletRequest request,HttpServletResponse response) throws Exception { Map<String, Object> map = null; List<Map<String,Object>> zplist = null; String responseText = ""; //String uuid = (String) request.getSession().getAttribute("uuid"); //String xhgh = (String) request.getSession().getAttribute("xhgh"); // String uuid = "10020"; String uuid = "10017"; String xhgh = "10017"; try { map = zpscDao.findStudentInfo(uuid); zplist = zpscDao.findZpInfo(uuid); if(map != null && map.size()>0){ String fileName = file.getOriginalFilename(); int index = fileName.lastIndexOf("."); String endFlag = fileName.substring(index); String changName = xhgh.concat(endFlag); System.out.println(path); File targetFile = new File(path, changName); if(!targetFile.exists()){ targetFile.mkdirs(); } file.transferTo(targetFile); String realPath = "瀵煎叆鐓х墖/"+lx+"/"+yx+"/"+zy+"/"+bj+"/"+changName+""; if(zplist != null && !zplist.isEmpty()){ zpscDao.updatePhotoPath(realPath,uuid); }else{ zpscDao.savePhotoPath(uuid,xhgh,realPath); } } } catch (Exception e) { log.error(e.getMessage()); e.printStackTrace(); } response.sendRedirect("content/template/zpsc/zpsc.jsp"); }
