Java获取访问者的userAgent,系统和浏览器版本

通过request获取userAgent

String userAgent = request.getHeader("User-Agent");  

创建一个UserAgentUtil

      将userAgent作为参数传入UserAgentUtil类中

public class UserAgentUtil {  
    public static Visit getUserAgent(String userAgent) {
    if(userAgent==""||userAgent==null){
    userAgent="";
    }
        if (userAgent.contains("Windows")) { 
        if (userAgent.contains("Windows NT 10.0")) {
                return judgeBrowser(userAgent, "Windows 10"); 
            } else if (userAgent.contains("Windows NT 6.2")) {  
                return judgeBrowser(userAgent, "Windows 8");
            } else if (userAgent.contains("Windows NT 6.1")) {
                return judgeBrowser(userAgent, "Windows 7" );  
            } else if (userAgent.contains("Windows NT 6.0")) {
                return judgeBrowser(userAgent, "Windows Vista");  
            } else if (userAgent.contains("Windows NT 5.2")) {
