Maven 构建浏览器解析userAgent类

创建Maven项目

添加pom.xml 依赖

获取浏览器版本：window.navigator.userAgent

window.navigator.userAgent
"Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/66.0.3359.181 Safari/537.36"

应用代码

package com.xusan;

import java.io.IOException;

import cz.mallat.uasparser.OnlineUpdater;
import cz.mallat.uasparser.UASparser;
import cz.mallat.uasparser.UserAgentInfo;

/**

public class UserAgentUtil {
	static UASparser uasParser = null;

    // 初始化uasParser对象
    static {
        try {
            uasParser = new UASparser(OnlineUpdater.getVendoredInputStream());
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    public static void main(String[] args) {
		

        String str = "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/66.0.3359.181 Safari/537.36";
        System.out.println(str);
        try {
            UserAgentInfo userAgentInfo = UserAgentUtil.uasParser.parse(str);
            System.out.println("操作系统名称："+userAgentInfo.getOsFamily());//
            System.out.println("操作系统："+userAgentInfo.getOsName());//
            System.out.println("浏览器名称："+userAgentInfo.getUaFamily());//
            System.out.println("浏览器版本："+userAgentInfo.getBrowserVersionInfo());//
            System.out.println("设备类型："+userAgentInfo.getDeviceType());
            System.out.println("浏览器:"+userAgentInfo.getUaName());
            System.out.println("类型："+userAgentInfo.getType());

        } catch (IOException e) {
            e.printStackTrace();
        }
    }

}
