java 获取用户关闭页面 java获取useragent

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")) {
