springboot如何获取请求者的ip地址

        // 在请求处理之前调用，可以记录IP地址等信息
        String clientIpAddress = getClientIpAddress(request);
        System.out.println("IP地址：" + clientIpAddress);
        return true;
    }
    @Override
    public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler,
            ModelAndView modelAndView) throws Exception {
        // 在请求处理之后调用，但在视图渲染之前
    }
    @Override
    public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex)
            throws Exception {
        // 在整个请求完成后调用，可以进行一些清理工作
    }

        String ipAddress = request.getHeader("X-Forwarded-For");
