+# spring-oauth2-minio-api
+## Teck Stack:
+Spring boot , oauth2 , liquibase , Minio-api for file management , Postgres DB and Pgadmin using docker compose file
+
+1) The flow of the project is the normal oauth2 flow where i am using Password grant_type
+2) I am using refreshing mechanism and as we all know the refreshing mechanism is responsibilty of client so my client in my case was Postman
+so, within the collection in the repo you will find [ pre-request ] script to check whether the access_token expired or not
+i mean you didn't need to call the request for token api just call the resource server's endpoint directly and it will work as inside the authorization header I passed the collection variable that i set the token insdie when the token expired
+
+3) i defined liquibase script to define 2-admin users [Rohan , Bushra] so i can use them to request token from the server
+
+4) the resource server deal with file management so, i used Minio's Api where Minio allows the upload and download of files for containerized applications, respecting the interfaces of Amazon S3 solution using the terms of amazon S3 like bucket but upload your files to your own server not on the cloud 
+but in my case instead of put extra configuration as it is just task i used the public server of minio company which is https://play.min.io/minio/
+
+5) I added Unit Test and Integration Test to my code using Junit 5 (jupiter) and mockito
