spring mvc多文件上传时报错怎么办？

1、确拍早认；\x0d\x0a2、确认commons-fileupload.jar 和 org.springframework.web.jar 存在环境\x0d\x0a3、MultipartHttpServletRequest multipartRequest = (MultipartHttpServletRequest)request；\x0d\x0a这一句会报颂贺腔错：ApplicationHttpRequest cannot be cast to MultipartHttpServletRequest\x0d\x0a　野衫　解决办法是通过这种方式：\x0d\x0aMultipartResolver resolver = new CommonsMultipartResolver(request.getSession().getServletContext())\x0d\x0aMultipartHttpServletRequest multipartRequest = resolver.resolveMultipart(request)

当在上传表单中设置了 enctype="multipart/form-data" 时post传过去的弯哪链字符串的值为null，会报 HTTP Status 400 - Required String parameter 'description' is not present 错误。

解决方案：

1、首先在pom.xml中添加

然后在applicationContext.xml中添埋孙加即可解决，这样的话spring会对表单的数据进行处理，就算使用了enctype="multipart/form-data"进行传值也缓培能拿到数据
