Auto-configured MultipartConfigElement prevents CommonsMultipartResolver from resolving request parts #7735
Description
I used Spring Boot 1.2.6 before, So I want to upgrade Spring Boot to 1.4.2 and upgrade Spring Framework to 4.3.5, when I changed my maven pom, The Apache Commons FileUpload parseRequest() returning no items. Then I changed Spring Boot to 1.3.8 and Spring Framework to 4.2.8, the Apache Commons FileUpload can work. I don't know why. The following is my maven pom and my code.

Code
DiskFileItemFactory factory = new DiskFileItemFactory();
factory.setSizeThreshold(1 * 1024 * 1024);
File tmpDir = new File("tempfile");
if (!tmpDir.exists()) {
tmpDir.mkdir();
}
File uploadtmp = new File("uploadtmp");
if (!uploadtmp.exists()) {
uploadtmp.mkdir();
}
factory.setRepository(tmpDir);
ServletFileUpload sfu = new ServletFileUpload(factory);
sfu.setFileSizeMax(-1);
sfu.setSizeMax(-1);
sfu.setHeaderEncoding("UTF-8");
List<FileItem> fileItems = (List<FileItem>) sfu.parseRequest(request);
When I use Spring Boot 1.4.2 and Spring Framework 4.3.5, the fileItems is empty.
