拦截器Interceptor 记录访问信息，通过aspect也可以，下面是通过Interceptor记录的

@Override
        public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
        response.setHeader("Access-Control-Allow-Origin", "*");
        response.setHeader("Access-Control-Allow-Headers", "Content-Type, Authorization");
        response.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, PUT");
        //url
        LOGGER.info("url={}", request.getRequestURL());
        //method
        LOGGER.info("method={}", request.getMethod());
        //ip
        LOGGER.info("ip={}", request.getRemoteAddr());
        if (handler instanceof HandlerMethod) {
        HandlerMethod h = (HandlerMethod) handler;
        //类方法
        LOGGER.info("class_method={}", h.getBean().getClass().getName() + "." + h.getMethod().getName());
    
        //参数
        LOGGER.info("args={}", getParamString(request.getParameterMap()));
    
    //  StringBuilder sb = new StringBuilder(1000);
    //
    //  sb.append("Controller: ").append(h.getBean().getClass().getName()).append("\n");
    //  sb.append("Method : ").append(h.getMethod().getName()).append("\n");
    //  sb.append("Params : ").append(request.getParameterMap()).append("\n");
    //  sb.append("URI : ").append(request.getRequestURI()).append("\n");
    //  System.out.println(sb.toString());
        }
    
            return !request.getMethod().equals("OPTIONS");
        }
    
        private String getParamString(Map<String, String[]> map) {
            StringBuilder sb = new StringBuilder();
            for (Map.Entry<String, String[]> e : map.entrySet()) {
                sb.append(e.getKey()).append(":");
                String[] value = e.getValue();
                if (value != null && value.length == 1) {
                    sb.append(value[0]).append("\t");
                } else {
                    sb.append(Arrays.toString(value)).append("\t");
                }
            }
            return sb.toString();
        }
