easyUI利用ajax上传文件后台

Posted 2021-02-28 AlphaJunS

结合前篇easyUI前端ajax上传文件组件

读取Excel工具类

及springMVC上传文件

后台代码

controller

@RequestMapping("/excelUploadItemList")
    @ResponseBody
    public CommonResponse excelUploadItemList(@RequestParam MultipartFile upFile, HttpServletRequest request, HttpServletResponse response) {
