jsp:include 通过变量作为路径动态引入

语法:<jsp:include page="<%=整体是个变量%>" flush="true"/>

 

示例:

<%@ page language="java" contentType="text/html;charset=UTF-8" pageEncoding="UTF-8"%>

<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

<%    
    // 用来确定是加载page1.jsp还是用来加载page2.jsp;
    {
        // ......        
    }
    
    // 假设确定的结果是加载page2.jsp    
    String loadPageUrl = "/jsp/page2.jsp";    
%>

</head>
<body>
    
    <div>
        这里是主页的内容:coding......
    </div>
    
    <!--
        动态的选择加载哪个jsp来构建页面;
    -->
    <jsp:include page="<%=loadPageUrl%>" flush="true"></jsp:include>
         
</body>
</html>
