The error indicates you have an issue with your FileUploadController, the bean is conflicting, two classes of the same name with Spring unable to determine which one to use, try creating an alias and a qualifier or give it a different name so it doesn't conflict.

For an example using spring boot and file upload check it this example: https://github.com/Rob-Leggett/gradle_springboot_microservice
