使用Java ?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

?应用:

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:
