jsp包含文件的兩種方法

 1 //第一種：include指令：當JSP轉換成Servlet時引入指定文件 <%@ page contentType="text/html; charset=GB2312" language="java" errorPage=""%>    
 2 <%@ include file="head.jsp"%>   
 3 <%@ include file="body.jsp"%>   
 4 <%@ include file="tail.jsp"%>   
 5 //第二種：<jsp:include>動作元素：當JSP頁面被請求時引入指定文件    
 6 <%@ page contentType="text/html; charset=GB2312" language="java" errorPage=""%>   
 7 <jsp:include page="head.jsp"/>   
 8 <jsp:include page="body.jsp"/>   
 9 <jsp:include page="tail.jsp"/>   
10   
11   
12 //第二種方法可以很方便的用<jsp:param>來向所包含頁傳遞參數，方法如下：    
13 <%@ page contentType="text/html; charset=GB2312" language="java" errorPage=""%>   
14 <jsp:include page="head.jsp"/>   
15 <jsp:include page="body.jsp">   
16 <jsp:param name="uid" value="username"/>   
17 <jsp:param name="pwd" value="password"/>   
18 </jsp:include>   
19 <jsp:include page="tail.jsp"/>
