In software development, Monolithic and Microservices are two popular architectural styles used to build applications, and they differ in how the application is structured and managed.
Implementing User Authentication in a Full Stack Java Application
User authentication is a key feature in any secure full-stack Java application. A typical stack might include Spring Boot for the backend and React or Angular for the frontend.
On the backend, Spring Security is the go-to tool. It provides powerful features like login, logout, session management, and role-based access control. Start by adding Spring Security to your Maven or Gradle project. Then, create a User entity, a User Details Service to load user data, and a Security Config class to customize authentication rules.
On the frontend, you create login and registration forms that interact with REST APIs. Use HTTP-only cookies or tokens (like JWT) to manage sessions securely.
After login, restrict access to routes based on user roles. For example, only admins can access admin pages.
Whether you're building a blog or enterprise app, strong authentication keeps users and data secure.
