The implementation is similar to above logic except it has a DB call to save the file instead of saving it to the local file system. You have already noticed the response of the file upload. The below implementation only difers in the process of getting the file from databse rather then a file system. While downloading multiple files, we can create a zip file in spring boot and download that zip file alone rather then downloading multiple files individually.

Here, we will be using ZipOutputStream from java. Below is the example. To test this functionality, we can make a GET request with name as a query parameter which includes all the file names that we want to be included in the final.
