No particular error were identified, and I could not find the project in this repo called spring boot file upload to compare, which is quite unfortunate. What's the source of the problem. I'm sure it's not the size of the upload file, since I've encountered this problem and the console returned an error message for the size. I replace the large file with a tiny one so that the error message didn't come up again. However the webpage became what's described above。
