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();
    }
