Spring Interceptors | Configure HandlerInterceptors | Explanation with Example

Spring Interceptor are used to intercept client requests and process them.
HandlerInterceptor is basically similar to a Servlet Filter, but in contrast to the latter it just allows custom pre-processing with the option of prohibiting the execution of the handler itself, and custom post-processing. Provides us with three pre-define methods -

* postHandle() This method is used to perform some action on responses sent to the client.
* afterCompletion() This method is used to perform actions after request and response.
