AuthService

AuthService is a Spring Boot application that provides authentication and authorization functionality using JWT (JSON Web Tokens). It is designed as a RESTful API service, making it easy to integrate with other applications that require secure user authentication.

Key Features

• Spring Boot & Spring Security: Utilizes Spring Boot for rapid development and Spring Security for robust authentication and authorization.
• JWT Authentication: Issues and validates JWT tokens for stateless, secure authentication.
• User and Role Management: Supports user management with roles stored in a relational database.
• MySQL Database: Uses MySQL for persistent storage of user and token data.
• JPA & Hibernate ORM: Implements data persistence with JPA and Hibernate for seamless ORM.
• Refresh Token Support: Implements refresh tokens for secure, long-lived sessions.
• RESTful API Endpoints: Provides endpoints for authentication, user registration, and token management.
• Input Validation: Includes utility methods for validating usernames and emails.

Main Components

• Entities

  • UserInfo: Represents a user in the system, including username, password, and roles.
  • UserRole: Defines user roles for authorization.
  • RefreshToken: Stores refresh tokens associated with users.

• Repositories

  • UserInfoRepo: CRUD operations for user data.
  • RefreshTokenRepo: Manages refresh tokens.

• Services

  • MyUserDetailsService: Loads user details and handles user sign-up logic.
  • JwtService: Handles JWT creation, validation, and extraction.
  • MyUserDetails: Implements Spring Security's UserDetails for custom user info.

• Security

  • SecurityConfig: Configures authentication providers, password encoding, and security filters.
  • JwtAuthenticationFilter: Intercepts requests to validate JWT tokens.

• DTOs

  • UserInfoDto, AuthRequestDTO, JWTResponseDto: Used for transferring data between client and server.

• Utility

  • ValidateUtil: Provides input validation for usernames and emails.
