Spring MVC Interceptors allow you to execute common logic before and after controller methods without repeating the same code across every API. In this video, we understand Spring Boot Interceptors from first principles and follow the complete request lifecycle through `preHandle()`, `postHandle()`, and `afterCompletion()`. You will learn: What a Spring MVC Interceptor is Why interceptors are needed Where interceptors fit inside the Spring MVC request flow How `HandlerInterceptor` works Understanding `preHandle()`, `postHandle()`, and `afterCompletion()` How an interceptor can stop a request before it reaches the controller Registering interceptors using `WebMvcConfigurer` Applying interceptors to specific URL patterns Excluding public endpoints Logging controller and method information Measuring API execution time safely Authentication and authorization examples Execution order with multiple interceptors Filter and Interceptor execution flow together Filter vs Interceptor and when to use each By the end of this lecture, you will understand exactly what happens before and after a controller executes and how interceptors can be used to keep common MVC logic outside your controllers. This lecture is part of the complete Spring Boot course, where we are building every concept step by step from the fundamentals.
