인터럽트:

import org.springframework.web.servlet.HandlerInterceptor;
import org.springframework.web.servlet.ModelAndView;

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

@Slf4j
public class GlobalHandlerInterceptor implements HandlerInterceptor {
    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
        String requestURI = request.getRequestURI();
        log.info("preHandle [{}][{}]", requestURI, handler);
        return true; //false 진행X
    }

    @Override
    public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) throws Exception {
        String requestURI = request.getRequestURI();
        log.info("postHandle [{}][{}]", requestURI, handler);
    }

    @Override
    public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) throws Exception {
        String requestURI = request.getRequestURI();
        log.info("afterCompletion requestURI [{}][{}]", requestURI, handler);
        if (ex != null) {
            log.error("afterCompletion error!!", ex);
        }
    }
}

 

@Configuration
public class WebConfig implements WebMvcConfigurer {
   
    .....
    
    //추가
    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(new GlobalHandlerInterceptor());
