I am using springboot 2.7.1 and uploading the Multipart file .
our application deals with huge number of files . i am reading the multipart file using byte[] = file.getBytes()

I could see lot of files are storing in the system temp location (c/user/appData/local/temp) with the prefix upload_xx_xxxx
few files are deleting and few files are not deleting it is causing out of memory error

since am using byte[] to read the file there is no resource leak as per my knowledge

how to handle this situation.

I tried changing the byte[] to inputStream for reading the file but not working

any suggestion
