✅Day 19: Spring Framework/SpringBoot:
✓Response Modification
✓Handling Request bodies
✓Filter Registration
While modifying requests and responses is technically possible using wrappers, it should be done sparingly as it can lead to fragile code and architectural issues, prioritizing standard controller logic where possible.

✅Day 19: Spring Framework/SpringBoot:
✓Why Filters are Needed: Filters allow for the execution of common, reusable logic (like logging and security) before a request reaches the DispatcherServlet and after the response is generated, keeping controllers clean.
-Logging
-Authentication:
-Request Identification
-Performance Tracking

Day 18: Spring Framework/SpringBoot:
✔️Spring Boot configurations and profiles: essential where code needs to run across different environments (e.g., local, dev, staging, production).
✓The Problem with Hardcoding: Security risks and lack of flexibility when moving between environments.
✓Configuration Files: https://t.co/Sk3rqakEL7 and application.yml files to externalize settings.
✓Spring Profiles: To handle environment specific needs.
✓External Configuration: Inject configurations via command line arguments or environment variables.
