Environment:

• Java version: 1.8
• Maven version: 3.*
• Spring Boot version: 2.2.1.RELEASE

Read-Only Files:

• src/test/*

Data:

Structure of a file object when stored in database:

{
   "id": 1,
   "fileGroup": "certificates",
   "fileName": "certificate1",
   "file": "bytes of file data"
}

Requirements:

The REST service needs to expose 2 API endpoints for files upload and download. Uploaded files needs to be stored in database. By default it supports H2 database.

Validations to be performed:

• If a file size exceeds 100KB, return status code INTERNAL_SERVER_ERROR and don't store file in database.
• Here you are expected to use file size limit constraint using configuration instead of doing programmatically.

Required API endpoints to be exposed

POST request to /uploader :

• this endpoint should be able to receive two parameters fileGroup and files
• store the files into database and return status code 201 as response
• if the user uploads same name's file with the same fileGroup again, the previous file should be replaced with the latest one and return status code 201.

GET request to /downloader:

• accept the fileGroup as a request parameter
• if there are more than one files under that fileGroup then it should return all the files of that group as a single zipped file like 'file_group_name.zip' with status code 200.
• if there is only one file then return that single file like fileName without zipping with status code 200.
• if there is no any files under that fileGroup then return 404 status code.

Your task is to complete the given project so that it passes all the test cases when running the provided unit tests. Required model class XFile for file has been already provided. You just need to implement the 2 endpoints in the controller class.
