Uploading Large Files With Springboot with additional data [HttpServlet]

Question

I am trying to upload big files with additional data for my upload using form-data and received it on the server side by using HttpServerletRequest.

let data = new FormData()
data.append("file", files[0])
data.append("project", "123")
data.append("userId", 1)

Was able to upload big files by using this solution SpringBoot: Large Streaming File Upload Using Apache Commons FileUpload

But the problem is it is missing some of the parameters I needed to proceed on the operation

it was returning null, specifically after adding spring.servlet.multipart.enabled=false

When I try this:

 String userId = request.getParameter("userId");
 String project = request.getParameter("project");

I was getting a null. Is there any solution for this?
