How are you handling authentication and authorization in SpringBoot applications?
In Spring Boot applications, authentication and authorization are usually handled using Spring Security.
1: Authentication means checking who the user is (like asking for username and password).
2: Authorization means checking what the user is allowed to do (like checking their roles or permissions).
How it works:
1: When a user tries to log in, Spring Security checks their credentials (authentication).
2: If the credentials are correct, Spring Security gives them access.
3: For each request, Spring Security checks if the user has permission to access that resource (authorization).
Example:
1: You can use in-memory users, a database, or external providers (like OAuth2) for authentication.
2: You can set up rules to allow or block access to certain URLs based on user roles.
In short:
Spring Boot uses Spring Security to make sure only the right people can log in and only see or do what they are allowed to.
