### 检查访问方式是手机端还是电脑端的工具类 ###

1.  对request请求头，user-agent的值进行正则判断

import java.util.regex.Matcher;
    import java.util.regex.Pattern;
    
    /**
     * 检测是否为移动端设备访问
     * @author Administrator
     *
     */
    public class CheckMobile {
        
    
    
    
        //手机
        static String phoneReg="\\b(ip(hone|od)|android|opera m(ob|in)i"  
                +"|windows (phone|ce)|blackberry"  
                +"|s(ymbian|eries60|amsung)|p(laybook|alm|rofile/midp"  
                +"|laystation portable)|nokia|fennec|htc[-_]"  
                +"|mobile|up.browser|[1-4][0-9]{2}x[1-4][0-9]{2})\\b";  
        //平板
        static String tableReg="\\b(ipad|tablet|(Nexus 7)|up.browser"  
                +"|[1-4][0-9]{2}x[1-4][0-9]{2})\\b";
    
        //移动设备正则表达式匹配：手机端、平板
        static Pattern phonePat =Pattern.compile(phoneReg,Pattern.CASE_INSENSITIVE);
        static Pattern tablePat =Pattern.compile(tableReg,Pattern.CASE_INSENSITIVE);
    
        public static boolean check(String userAgent){
            if(null==userAgent){
                userAgent="";
            }
            //开始匹配
            Matcher matcherPhone=phonePat.matcher(userAgent);
            Matcher matcherTable=tablePat.matcher(userAgent);
            if(matcherPhone.find()||matcherTable.find()){
                //移动设备入口
                return true;
            }else{
                //pc端入口
                return false;
            }
        }
    }

2.调用

/**
         * 检查访问方式
         */
        public void checkEquipment(HttpServletRequest request,HttpServletResponse response){
            String ua=(String) session.getAttribute(request,"ua");
            if(null==ua){
                try{
                    String userAgent = request.getHeader( "USER-AGENT" ).toLowerCase();
                    if(null == userAgent){  
                        userAgent = "";  
                    }
                    if(CheckMobile.check(userAgent)){
                        ua="mobile";
                    } else {
                        ua="pc";
                    }
    
                    session.setAttribute(request, response, "ua",ua);
                }catch(Exception e){}
            }
            if(StringUtils.isNotBlank((ua) )){
                request.setAttribute("ua", ua);
            }
        }
