在web开发做手机站的时候会遇到这个问题,就是如果判断用户的请求是来自手机端还是pc端
我的实现思路是创建一个拦截器,对首页的url进行拦截,在拦截的过程中获取用户请求头中的User-Agent,这个是记录着用户登录设备信息的
网上有工具类,判断请求头User-Agent的工具类
//判断是否为手机浏览器
public static boolean JudgeIsMoblie(HttpServletRequest request) {
boolean isMoblie = false;
String[] mobileAgents = { "iphone", "android","ipad", "phone", "mobile", "wap", "netfront", "java", "opera mobi",
"opera mini", "ucweb", "windows ce", "symbian", "series", "webos", "sony", "blackberry", "dopod",
"nokia", "samsung", "palmsource", "xda", "pieplus", "meizu", "midp", "cldc", "motorola", "foma",
"docomo", "up.browser", "up.link", "blazer", "helio", "hosin", "huawei", "novarra", "coolpad", "webos",
"techfaith", "palmsource", "alcatel", "amoi", "ktouch", "nexian", "ericsson", "philips", "sagem",
"wellcom", "bunjalloo", "maui", "smartphone", "iemobile", "spice", "bird", "zte-", "longcos",
"pantech", "gionee", "portalmmm", "jig browser", "hiptop", "benq", "haier", "^lct", "320x320",
"240x320", "176x220", "w3c ", "acs-", "alav", "alca", "amoi", "audi", "avan", "benq", "bird", "blac",
"blaz", "brew", "cell", "cldc", "cmd-", "dang", "doco", "eric", "hipt", "inno", "ipaq", "java", "jigs",
"kddi", "keji", "leno", "lg-c", "lg-d", "lg-g", "lge-", "maui", "maxo", "midp", "mits", "mmef", "mobi",
"mot-", "moto", "mwbp", "nec-", "newt", "noki", "oper", "palm", "pana", "pant", "phil", "play", "port",
"prox", "qwap", "sage", "sams", "sany", "sch-", "sec-", "send", "seri", "sgh-", "shar", "sie-", "siem",
"smal", "smar", "sony", "sph-", "symb", "t-mo", "teli", "tim-", "tosh", "tsm-", "upg1", "upsi", "vk-v",
"voda", "wap-", "wapa", "wapi", "wapp", "wapr", "webc", "winw", "winw", "xda", "xda-",
"Googlebot-Mobile" };
if (request.getHeader("User-Agent") != null) {
String agent=request.getHeader("User-Agent");
for (String mobileAgent : mobileAgents) {
if (agent.toLowerCase().indexOf(mobileAgent) >= 0&&agent.toLowerCase().indexOf("windows nt")<=0 &&agent.toLowerCase().indexOf("macintosh")<=0) {
isMoblie = true;
break;
}
}
}
return isMoblie;

写一个拦截器如果是电脑访问 放行,手机访问的话跳转到手机首页的url
注意在springMvc.xml配置文件配置拦截器的拦截路径 
public class IntercepterMobile extends HandlerInterceptorAdapter{
public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) throws Exception {
super.afterCompletion(request, response, handler, ex);
}
public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) throws Exception {
super.postHandle(request, response, handler, modelAndView);
}
public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
boolean judgeIsMoblie = SingletonLoginUtils.JudgeIsMoblie(request);
if(judgeIsMoblie==true){
response.sendRedirect("/mobile/index");
}else{
return true;
}
return true;
}
