java.lang.NoSuchMethodException

使用spring 框架上传图片的时候 出现这个异常

经查询

解决办法如下

原来的写法

@RequestMapping(value = "/service/uploadImg",method = RequestMethod.POST)@ResponseBodypublic BaseTransferEntity uploadImg(HttpServletRequest request,HttpServletResponse response,MultipartFile[] files) {List<Map<String, Object>> lst = new ArrayList<Map<String, Object>>();try {//上传人String userId = request.getParameter("userId");

修改之后的写法

@RequestMapping(value = "/service/uploadImg",method = RequestMethod.POST)@ResponseBodypublic BaseTransferEntity uploadImg(HttpServletRequest request,HttpServletResponse response,@RequestParam("files") MultipartFile[] files) {List<Map<String, Object>> lst = new ArrayList<Map<String, Object>>();try {//上传人String userId = request.getParameter("userId");

对 没错 在参数加入这个标签@RequestParam
