## Overview

This is a Spring Boot authentication-service codebase. Its evident sign-in support path loads a user from persistence, then adapts the user and roles into Spring Security details. Separate service code provides JWT parsing/validation and refresh-token creation and expiry checks. The tree and excerpts contain no controller, security configuration, or substantive README, so the request entry point and wiring of token services are not established; those connections are intentionally omitted.

Main entry points: [`src/main/java/com/authService/Service/RefreshTokenService.java`](https://github.com/mohankumarsl2005/authenticationservice/blob/main/src/main/java/com/authService/Service/RefreshTokenService.java) (Refresh tokens), [`src/main/java/com/authService/Service/UserDetailServiceImp.java`](https://github.com/mohankumarsl2005/authenticationservice/blob/main/src/main/java/com/authService/Service/UserDetailServiceImp.java) (User lookup), [`src/main/java/com/authService/repository/UserRepository.java`](https://github.com/mohankumarsl2005/authenticationservice/blob/main/src/main/java/com/authService/repository/UserRepository.java) (User repository), [`src/main/java/com/authService/repository/RefreshTokenRepository.java`](https://github.com/mohankumarsl2005/authenticationservice/blob/main/src/main/java/com/authService/repository/RefreshTokenRepository.java) (Token repository)
