SpringMVC+ajaxFileUpload 上传文件出现Required MultipartFile parameter 'file' is not present错误,
找了很久原因,发现是前端的
fileElementId: 'file1',中file1一定要与Controller中
@RequestMapping(value ="fileUpload",method ={RequestMethod.POST,RequestMethod.GET})
public String fileUpload(@RequestParam MultipartFile file1,HttpServletRequest request,HttpServletResponse response) {...}
file1的名字相对应。
