Java servlet判断是否是移动设备-白红宇

使用 servlet如何判断访问介质是否是移动设备呢?

移动设备指手机和pad

       Java代码

    }  

应用:

       Java代码   
String userAgent=request.getHeader("user-agent");  
        ClientOsInfo info= HeaderUtil.getMobilOS(userAgent);  
        System.out.println("device type:\t"+info.getDeviceType());  
        System.out.println("type version:\t"+info.getOsTypeVersion());  
        System.out.println("version:\t"+info.getVersion());  
        System.out.println("是移动设备吗:"+info.isMobile());  

运行结果:
