在spring中使用UserAgentUtil获取访问者的信息

导入依赖

<dependency>
            <groupId>eu.bitwalker</groupId>
            <artifactId>UserAgentUtils</artifactId>
            <version>1.21</version>
        </dependency>

对象获取

使用 HttpServletRequest 获取User-Agent(用户代理)，然后再获取UserAgent（解析agent字符串），Browser（获取浏览器对象），OperatingSystem（获取操作系统对象）。

代码

String agent=httpServletRequest.getHeader("User-Agent");
//解析agent字符串
        UserAgent userAgent = UserAgent.parseUserAgentString(agent);
//获取浏览器对象
        Browser browser = userAgent.getBrowser();
//获取操作系统对象
        OperatingSystem operatingSystem = userAgent.getOperatingSystem();
 
        System.out.println("浏览器名:"+browser.getName());
        System.out.println("浏览器类型:"+browser.getBrowserType());
        System.out.println("浏览器家族:"+browser.getGroup());
        System.out.println("浏览器生产厂商:"+browser.getManufacturer());
        System.out.println("浏览器使用的渲染引擎:"+browser.getRenderingEngine());
        System.out.println("浏览器版本:"+userAgent.getBrowserVersion());
 
        System.out.println("操作系统名:"+operatingSystem.getName());
        System.out.println("访问设备类型:"+operatingSystem.getDeviceType());
        System.out.println("操作系统家族:"+operatingSystem.getGroup());
        System.out.println("操作系统生产厂商:"+operatingSystem.getManufacturer());
        System.out.println("IP地址:"+httpServletRequest.getRemoteAddr());

使用:返回的UserAgent对象就是解析后的

UserAgent userAgent = UserAgent.parseUserAgentString(str);

第二种Hutool工具

<!-- https://mvnrepository.com/artifact/cn.hutool/hutool-all -->
<dependency>
    <groupId>cn.hutool</groupId>
    <artifactId>hutool-all</artifactId>
    <version>5.8.10</version>
</dependency>

UserAgent ua = UserAgentUtil.parse("5.0 (Linux; Android 6.0; Nexus 5 Build/MRA58N) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/91.0.4472.124 Mobile Safari/537.36");

Console.log(ua.getOsVersion()); // 6.0
