Master Java Web Services and REST API with Spring Boot- Step 11 - Implementing Exception Handling - 404 Resource Not Fou

The video tutorial covers the importance of returning correct HTTP response statuses, particularly focusing on handling cases where a user is not found. Initially, a 200 OK status is returned even when a resource does not exist, which is incorrect. The tutorial demonstrates how to throw a specific 'UserNotFoundException' and configure it to return a 404 Not Found status using Spring Boot annotations. It emphasizes the need for consistent exception messages across services and introduces the concept of a standard exception structure for better error handling.
