实现导航栏
1. 按照第一篇新建一个Hello World程序，修改入口函数为
@RequestMapping(value = "/") public String ShowNav() { return "page1"; }
2. 在src/main/webapp/WEB-INF/views下建一个page1.jsp
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<%@ page session="false"%>
<%@ page language="java" contentType="text/html; charset=UTF-8"
import="java.util.*" pageEncoding="UTF-8"%>
<html>
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">
<meta name="description" content="">
<meta name="author" content="">
<title>Page1</title>
<!-- 使用bootstrap框架，美化登录界面 -->

<div id="wrapper">
<%@ include file="navigation.jsp"%>
<div id="page-wrapper">
</div><!-- /#page-wrapper -->
