一篇关于SpringMVC 传统文件上传的方法
一、界面效果
二、html代码
1 <legend>上传APK文件</legend> 2 <form action="<%=basePath%>/apks/commitApk" class="form-horizontal" method="post" enctype="multipart/form-data"> 5 <div class="form-group"> 6 <label for="ticket-message" class="col-sm-3 control-label col-md-1">版本号</label> 7 <div class="col-md-4"> 8 <input type="text" class="form-control" name="versionCode" id="versionCode" placeholder="请输入整数"> 9 </div> 10 </div> 11 <div class="form-group"> 12 <label for="ticket-message" class="col-sm-3 control-label col-md-1">版本名</label> 13 <div class="col-md-4"> 14 <input type="text" class="form-control" name="versionName" id="versionName" placeholder="0.0.0.1"> 15 </div> 16 </div> 17 <div class="form-group"> 18 <label for="ticket-message" class="col-sm-3 control-label col-md-1">描述</label> 19 <div class="col-md-4"> 20 <textarea class="form-control" name="versionDesc" id="versionDesc" rows="5" cols="30" placeholder="版本描述"></textarea> 21 </div> 22 </div> 23 <div class="form-group"> 24 <label for="ticket-message" class="col-sm-3 control-label col-md-1">文件</label> 25 <!-- <label for="ticket-attachment" class="col-sm-3 control-label">请选中apk文件</label> --> 26 <div class="col-md-4"> 27 <input type="file" name="apkFile" id="apkFile"> 28 <p class="help-block"><em>文件类型: .apk</em></p> 29 </div> 30 </div> 31 <div class="form-group"> 32 <label for="ticket-message" class="col-sm-3 control-label col-md-1"></label> 33 <div class="col-md-4"> 34 <input id="apkSubmitBtn" type="submit" class="btn btn-danger"></input> 35 </div> 36 </div> 37 </form>
三、后台java代码
1 @RequestMapping(value = "/commitApk", method = RequestMethod.POST) 2 public @ResponseBody ModelAndView commitApk( 3 @RequestParam("apkFile") CommonsMultipartFile[] apkFile,@RequestParam("versionCode") int versionCode,@RequestParam("versionName") String versionName, 4 @RequestParam("versionDesc") String versionDesc, HttpSession session) { 5 FileOutputStream out = null; 6 FileInputStream in = null; 7 try { 8 String appPath = System.getProperty("root"); 9 appPath = xxx;14 File fileDir = new File(buffer.toString()); 15 if(!fileDir.exists()) { 16 fileDir.mkdirs(); 17 } 18 buffer.append(apkFile[0].getFileItem().getName()); 19 File file = new File(buffer.toString()); 20 if(!file.exists()) { 21 file.createNewFile(); 22 } else { 23 file.delete();//如果存在就删除重新上传 24 } 25 out = new FileOutputStream(file); 26 27 in = (FileInputStream)apkFile[0].getInputStream(); 28 int read = 0; 29 byte[] b = new byte[1024]; 30 while((read = in.read(b)) != -1) { 31 out.write(b, 0, read); 32 } 33 //数据入库 34 ApkManagerPo apkManagerPo = new ApkManagerPo(); 35 apkManagerPo.setApkCode(UUID.randomUUID().toString()); 36 apkManagerPo.setCreateDate(new SimpleDateFormat(Constants.DATE_FORMAT).format(new Date()));39 apkManagerPo.setVersionCode(versionCode); 40 apkManagerPo.setVersionName(versionName); 41 apkManagerPo.setVersionDesc(versionDesc); 42 if(session.getAttribute("User") != null) { 43 UserPo user = (UserPo)session.getAttribute("User"); 44 apkManagerPo.setUserId(user.getUserId()); 45 }else { 46 apkManagerPo.setUserId(""); 47 } 48 apkManagerPo.setApkRoute(xx);//文件夹放在webApp下面 49 apkManagerPo.setApkPath(xx); 50 apkService.addApkVersion(apkManagerPo); 51 } catch (Exception e) { 52 e.printStackTrace(); 53 } finally { 54 try { 55 if(out != null) { 56 out.close(); 57 } 58 if(in != null) { 59 in.close(); 60 } 61 } catch (IOException e) { 62 e.printStackTrace(); 63 } 64 } 65 return null; 66 }
此代码为form表单提交，现改需要改为js提交，故做记录
一个用于ajax上传的js插件
