	<!-- Interceptors -->
	<mvc:interceptors>
		<mvc:interceptor>
			<mvc:mapping path="/**" /> 
			<beans:bean class="com.donggyu.project.comm.logger.CustomInterceptor" />
		</mvc:interceptor>
	</mvc:interceptors>

CustomInterceptor.java 생성

comm > logger > CustomInterceptor.java

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.handler.HandlerInterceptorAdapter;

public class CustomInterceptor extends HandlerInterceptorAdapter {
	protected Log log = LogFactory.getLog(CustomInterceptor.class);

	@Override
	public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler)
			throws Exception {
		log.info("====================================== START ======================================");
		log.info(" Request URI \t: " + request.getRequestURI());

		return super.preHandle(request, response, handler);
	}

	@Override
	public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler,
			ModelAndView modelAndView) throws Exception {
		log.info("====================================== END ======================================\n");
		super.postHandle(request, response, handler, modelAndView);
	}

	@Override
	public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex)
			throws Exception {
		log.info("====================================== afterCompletion ======================================\n");
		super.afterCompletion(request, response, handler, ex);
	}
