$("#subm").click(function(){ var formData = new FormData(); formData.append("appFile", document.getElementById("appFile").files[0]); alert("8888888888888888888888888"); $.ajax({ url: '${ctx}/appresources/fileUpload.shtml', type: "POST", data: formData, dataType: "json", contentType: false, processData: false, success: function (data) { alert("上传成功"); $("#versionCode").val(data.versionCode); $("#appVersion").val(data.appVersion); $("#appPackageName").val(data.appPackageName); }, error: function () { alert("上传失败！"); } }); });
后台处理：
@ResponseBody @RequestMapping("fileUpload") public JSONObject fileUpload(MultipartFile appFile,Model model,HttpServletRequest request,HttpServletResponse response) { ServletContext //........................省略 String infos=ApkUtil.getApkInfo(needPath+"source"+File.separator+"apk"+File.separator+fileName); String[] info=infos.split(","); String versionCode=info[0];//版本号 String versionName=info[1];//版本名 String packageName=info[2];//包名 String appName=fileName; AppResourcesFormMap appResourcesFormMap = getFormMap(AppResourcesFormMap.class); appResourcesFormMap.put("appName",fileName); appResourcesFormMap.put("appVersion",versionName); appResourcesFormMap.put("appPackageName",packageName); appResourcesFormMap.put("versionCode", versionCode); System.out.println(appResourcesFormMap); //model.addAttribute("appresources", appResourcesFormMap); JSONObject fromObject = JSONObject.fromObject(appResourcesFormMap); //String string = fromObject.toString(); return fromObject; }
