JSP中的兩種包含頁面的方法

//第一種：include指令：當JSP轉換成Servlet時引入指定檔案 <%@ page contentType="text/html; charset=GB2312" language="java" errorPage=""%><br /><%@ include file="head.jsp"%><br /><%@ include file="body.jsp"%><br /><%@ include file="tail.jsp"%><br />//第二種：<jsp:include>動作元素：當JSP頁面被請求時引入指定檔案<br /><%@ page contentType="text/html; charset=GB2312" language="java" errorPage=""%><br /><jsp:include page="head.jsp"/><br /><jsp:include page="body.jsp"/><br /><jsp:include page="tail.jsp"/> </p><p>//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：<br /><%@ page contentType="text/html; charset=GB2312" language="java" errorPage=""%><br /><jsp:include page="head.jsp"/><br /><jsp:include page="body.jsp"><br /><jsp:param name="uid" value="username"/><br /><jsp:param name="pwd" value="password"/><br /></jsp:include><br /><jsp:include page="tail.jsp"/> </p><p>
