User Management System (Spring Boot Microservice)

This project is a robust User Management microservice built using Spring Boot and Java. It provides essential functionalities for user creation, management, and secure authentication using Basic Security and JWT (JSON Web Tokens).

---

🚀 Key Features

• User Creation API: A secure REST endpoint for registering new users.
• Basic Security: Implementation of Spring Security for API protection.
• JWT Authentication: Generation and validation of tokens for authorized access.
• RESTful API Design: Clean, standard-compliant endpoints for all operations.
• Logging & Debugging: Configured with robust logging (app.log) for easy monitoring and troubleshooting.
• Maven Build System: Standardized project structure and dependency management.

🔄 Project Status & Contribution

This project is in active development.

• Frequent Feature Additions: I am continuously working on enhancing the system's functionality, adding new endpoints and services regularly.
• Bug Fixes: The codebase is actively monitored, and bug fixes are prioritized and implemented promptly to maintain system stability and reliability.

🔒 Security Implementation

The system uses Spring Security configured with JWT.

• User credentials are validated upon login, issuing a unique JWT.
• Subsequent requests require this token in the Authorization: Bearer <token> header to access protected resources.

📄 Logging

Application logs are configured to output to the console by default and also saved to app.log in the root directory for persistent monitoring.
