springboot获取请求ip、系统、浏览器等信息

1、添加依赖

<!-- https://mvnrepository.com/artifact/eu.bitwalker/UserAgentUtils -->
        <dependency>
            <groupId>eu.bitwalker</groupId>
            <artifactId>UserAgentUtils</artifactId>
            <version>1.21</version>
        </dependency>

2、使用方法

UserAgent userAgent = UserAgent.parseUserAgentString(request.getHeader("user-agent"));
        String clientType = userAgent.getOperatingSystem().getDeviceType().toString();
        LOGGER.info("clientType = " + clientType);   //客户端类型  手机、电脑、平板
        String os = userAgent.getOperatingSystem().getName();
        LOGGER.info("os = " + os);    //操作系统类型
        String ip = IpUtil.getIpAddr(request);
        LOGGER.info("ip = " + ip);    //请求ip
        String browser = userAgent.getBrowser().toString();
        LOGGER.info("browser = " + browser);    浏览器类型

　　//其中ip的获取方式

    public static String getIpAddr(HttpServletRequest request) {

        String ip = request.getHeader("x-forwarded-for");

        if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
            ip = request.getHeader("X-Real-IP");
            //LOGGER.error("X-Real-IP:"+ip);
        }
        if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
            ip = request.getHeader("http_client_ip");
　　　　　　//            LOGGER.error("http_client_ip:"+ip);
        }
        if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
            ip = request.getRemoteAddr();
　　　　　　//            LOGGER.error("getRemoteAddr:"+ip);
        }
        if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
            ip = request.getHeader("Proxy-Client-IP");
　　　　　　//            LOGGER.error("Proxy-Client-IP:"+ip);
        }
        if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
            ip = request.getHeader("WL-Proxy-Client-IP");
　　　　　　//            LOGGER.error("WL-Proxy-Client-IP:"+ip);
        }
        if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
            ip = request.getHeader("HTTP_X_FORWARDED_FOR");
　　　　　　//            LOGGER.error("HTTP_X_FORWARDED_FOR:"+ip);
        }
        　　// 如果是多级代理，那么取第一个ip为客户ip
        if (ip != null && ip.indexOf(",") != -1) {
            ip = ip.substring(ip.lastIndexOf(",") + 1, ip.length()).trim();
　　　　　　//            LOGGER.error("ip:"+ip);
        }
        return ip;
    }
