1.定义一个公共的JSP:首先引入jstl，再定义一个项目的基本路径。

tag.jsp

<%@ taglib uri="http://java.sun.com/jsp/jstl/core"  prefix="c"%>

<%@ taglib uri="http://java.sun.com/jsp/jstl/fmt"  prefix="fmt"%>
<%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions"%> 

<c:set var="baseurl" value="${pageContext.request.contextPath}/"></c:set>

 2.其他JSP页面通过静态包含引入上面的JSP内容

<%@ include file="/tag.jsp"%>

3. 也可以将公共的css与js引入连接抽出来放入一个JSP中

cssJs.jsp

<script type="text/javascript" src="${baseurl}/js/jquery.min.js"></script>

<script type="text/javascript" src="${baseurl}/bs/js/bootstrap.js"></script>

<link rel="stylesheet" href="${baseurl}/bs/css/bootstrap.css"/>

<!--分页-->

<link rel="stylesheet" type="text/css" href="${baseurl}/controls/easyUI/themes/default/easyui.css"/>

<script src="${baseurl}/controls/easyUI/easyui-lang-zh_CN.js"></script>

<link rel="stylesheet" href="${baseurl}/controls/easyUI/themes/icon.css"/>

<script type="text/javascript" src="${baseurl}/controls/easyUI/jquery.easyui.min.js"></script>

<!--复杂时日-->

<link rel="stylesheet" type="text/css" media="all" href="${baseurl}/controls/calendar/daterangepicker-bs3.css"/>

<script type="text/javascript" src="${baseurl}/controls/calendar/moment.js"></script>

<script type="text/javascript" src="${baseurl}/controls/calendar/daterangepicker.js"></script>

<!--日历-->

<link rel="stylesheet" href="${baseurl}/controls/calendar/pikaday.css">

<script src="${baseurl}/controls/calendar/pikaday.js"></script>

<script src="${baseurl}/js/menu.js"></script>

<link rel="stylesheet" href="${baseurl}/css/public/indexpublic_style.css"/>

<script type="text/javascript" src="${baseurl }/controls/jedate/jquery.jedate.js"></script>

<script type="text/javascript" src="${baseurl }/js/dateformat.js"></script>

<link type="text/css" rel="stylesheet" href="${baseurl }/controls/jedate/skin/jedate.css">

4.其他页面中引用

注意:先引入tag.jsp再引入   其他使用baseurl的jsp

好处:只用引入上面的tag.jsp便可使用jstl与${baseurl}获取项目名字。

--------------页面中编写一个全局变量记录项目名字，在JS文件中可以用全局变量代替项目名字(便于写路径)------------------------

JSP中:

<script type="text/javascript">

    var contextPath = "${pageContext.request.contextPath}";

</script>

JS中写路径的时候比如:

    $.ajax({

        url : contextPath + '/findExam_findExamEmployeeByExamId.action',

        data : {

            "examId" : examId

        },

        type : 'POST',

        async : true,

        dataType : 'json',

        success : showExamEmployeesModal,

        error : function() {

            alert("查询考试员工信息失败！！！")

        }

    });

也可以将tag.jsp上面进行改造:

　　　　将记录项目名字的JS变量放在tag.jsp中，这样只用引入一个tag.jsp便可以在jsp中用${baseurl}表示项目根路径，在JS中用context获取项目根路径。

tag.jsp

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>

<%@ taglib uri="http://java.sun.com/jsp/jstl/fmt" prefix="fmt"%>

<%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions"%>

<c:set var="baseurl" value="${pageContext.request.contextPath}"></c:set>

<script type="text/javascript">

    /* 表示项目根路径，等价于   /Exam    */

    var contextPath = "${pageContext.request.contextPath}";

</script>

　　注意:静态引入相当于原封不动的将里面的内容包含进来。所以在被包含的页面不需要头和尾。
