@Bean(name = "multipartResolver")
public CommonsMultipartResolver multipartResolver() {
  final CommonsMultipartResolver multipartResolver = new 
  CommonsMultipartResolver();
  multipartResolver.setMaxUploadSize(MAX_FILE_UPLOAD_SIZE);
  return multipartResolver;
}
private static final long MAX_FILE_UPLOAD_SIZE = 1024L * 1024L * 4L;

You need to have

<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver" />

Your tag in JSP may not have enctype="multipart/form-data" as property , make form tag as , and this error will be removed. e.g. :

<form method="post" enctype="multipart/form-data">
</form>

Depending in your Spring version you may have to cast it properly - Do check this thread How to get a MultipartHttpServletRequest from RequestContextHolder?
