实现多个JSP页面共用一个菜单

将菜单栏代码独立为一个jsp页面

 1 <%@ page language="java" contentType="text/html; charset=UTF-8"
 2     pageEncoding="UTF-8"%>
 3 <nav class="navbar navbar-inverse navbar-fixed-top">
 4     <div class="container">
 5         <div class="navbar-header">
 6             <button type="button" class="navbar-toggle collapsed"
 7                 data-toggle="collapse" data-target="#navbar" aria-expanded="false"
 8                 aria-controls="navbar">
 9                 <span class="sr-only">Toggle navigation</span> <span
10                     class="icon-bar"></span> <span class="icon-bar"></span> <span
11                     class="icon-bar"></span>
12             </button>
13             <a class="navbar-brand" href="#">商城系统</a>
14         </div>
15         <div id="navbar" class="collapse navbar-collapse">
16             <ul class="nav navbar-nav">
17             <li class="dropdown"><a href="showgoods.do" >商城首页</a></li>

21                     <ul class="dropdown-menu">

27                     aria-expanded="false">商品 <span class="caret"></span></a>
28                     <ul class="dropdown-menu">

30                         <li><a href="querygoods.do">所有商品</a></li>
31                     </ul></li>
32             </ul>
33
34             <ul class="nav navbar-nav navbar-right">
35                 <li class="dropdown"><a href="#" class="dropdown-toggle"

37                     aria-expanded="false">${sessionScope.user.username} <span
38                         class="caret"></span></a>
39                     <ul class="dropdown-menu">

42             </ul>
43         </div>
44     </div>
45 </nav>
