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：

public String execute() { 
    HttpServletRequest request = ServletActionContext.getRequest(); 
    boolean isMoblie = JudgeIsMoblie(request); 
    if(isMoblie){ 
      return "phone"; 
    } 
    return "pc"; 
  } 
   
  public boolean JudgeIsMoblie(HttpServletRequest request) { 
    boolean isMoblie = false; 
    String[] mobileAgents = { "iphone","android","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","techfaith","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","audi","avan","blac","blaz","brew","cell","cmd-","dang","doco","eric","hipt","inno","ipaq","jigs","kddi","keji","leno","lg-c","lg-d","lg-g","lge-","maxo","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","sph-","symb","t-mo","teli","tim-",/*"tosh",*/ "tsm-","upg1","upsi","vk-v","voda","wap-","wapa","wapi","wapp","wapr","webc","winw","xda-","Googlebot-Mobile" }; 
    if (request.getHeader("User-Agent") != null) { 
      for (String mobileAgent : mobileAgents) { 
        <span class="comment" style="margin: 0px; padding: 0px; border: none; color: rgb(0,130,0); font-family: Consolas,'Courier New',Courier,mono,serif; line-height: 18px;">//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。</span> 
        if (request.getHeader("User-Agent").toLowerCase() 
            .indexOf(mobileAgent) >= 0) { 
          isMoblie = true; 
          break; 
        } 
      } 
    } 
    return isMoblie; 
  } 

Struts2

<span style="white-space:pre">    
</span><action name="name" class="你自己的action类"> 
      <result name="pc">download/main.jsp</result> 
      <result name="phone">download/productPH.jsp</result> 
    </action> 

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(表示本拍壳安欢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编程小技巧。
