The LoggerInterceptor will override the following methods-

preHandle() - This method is used to intercept the request before it is handed over to the handler method. If It turns a boolean value, true : continue the handler execution chain; false , stop the execution chain and return it.

postHandle() - This method is used to intercept the request after the handler execution, Here user can manipulate the ModelAndView object before render it to view page.

afterCompletion() - This is a HandlerInterceptor callback method called after the complete request has finished.

@Component
public class LoggerInterceptor implements HandlerInterceptor {

	Logger log = org.slf4j.LoggerFactory.getLogger(this.getClass());

	@Override
	public void afterCompletion(HttpServletRequest request,
			HttpServletResponse response, Object object, Exception arg3)
			throws Exception {
		log.info("Request is complete");
	}

	@Override
	public void postHandle(HttpServletRequest request,
			HttpServletResponse response, Object object, ModelAndView model)
			throws Exception {
		log.info("Handler execution is complete");
	}

	@Override
	public boolean preHandle(HttpServletRequest request,
			HttpServletResponse response, Object object) throws Exception {
		log.info("Before Handler execution");
		return true;
	}

}
