java后台判断客户端是手机/PC并返回不同页面的实例

这个代码其实不是由我本人发现的，而是在翻看公司项目时无意间发现，觉得很实用所以拿出来大家分享。

框架：Struts2+spring+ibatis，

主要实现是依靠Http请求头Header中的"User-Agent"来完成，好了，废话不多说直接上代码。

Action中：

publicStringexecute(){
HttpServletRequestrequest=ServletActionContext.getRequest();
booleanisMoblie=JudgeIsMoblie(request);
if(isMoblie){
return"phone";
}
return"pc";
}

publicbooleanJudgeIsMoblie(HttpServletRequestrequest){
booleanisMoblie=false;
String[]mobileAgents={"iphone","android","phone","mobile",
"wap","netfront","java","operamobi","operamini","ucweb",
"windowsce","symbian","series","webos","sony",
"blackberry","dopod","nokia","samsung","palmsource","xda",
"pieplus","meizu","midp","cldc","motorola","foma",

"wapr","webc","winw","winw","xda","xda-",
"Googlebot-Mobile"};
if(request.getHeader("User-Agent")!=null){
for(StringmobileAgent:mobileAgents){
//这里本宝宝表示不怎么了解它的内部原理，但是知道个大概意思就得了。
if(request.getHeader("User-Agent").toLowerCase()
.indexOf(mobileAgent)>=0){
isMoblie=true;
break;
}
}
}
returnisMoblie;
}

Struts2

好了，代码就只是这么多，木有了木有了。。。是不是感觉很简单的说，

虽然不是我写出来的，但是看到这个代码，也是有一种收获的，其实很多设置都是包含在请求头中的，因为不管是什么浏览器什么设备，它要通过http去调用一个请求，那么它就必定是有http协议，只要精通http协议，那么啥事都好办(表示本屌目前不懂http协议，而后努力学习学习，再来装逼)~~

以上这篇java后台判断客户端是手机/PC并返回不同页面的实例就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持毛票票。
