File storage service trial work

Prerequisites

• JDK 1.8
• Gradle 4.4

Usage

1. Build using gradle build
2. Do one of these to have a valid directory for the uploaded files
   • Create a subdirectory called files in the directory you will start the application
   • Configure a custom directory for the uploaded files. To do this create a file called application.properties in the directory where the built JAR file is present with the content storage.filesystem.path=path_to_your_file_storage_directory, where path_to_your_file_storage_directory is a directory in your file system.
3. Start the application with java -jar storage-service-0.1.jar
4. To upload a file send a multipart PUT request to http://localhost:8080/file-storage. It will return a string like GK/the_uploaded_filename. This is the path where the uploaded file is accessible. The first part (GK in this example) is to avoid filename collisions.
5. To download the uploaded file send a GET request to an URL like http://localhost:8080/file-storage/GK/the_uploaded_filename where the last two parts are values returned by the put request in the previous step.
