JSP中的两种包含页面的方法

[java] view plaincopy
//第一种：include指令：当JSP转换成Servlet时引入指定文件 <%@ page contentType="text/html; charset=GB2312" language="java" errorPage=""%>  
<%@ include file="head.jsp"%>  
<%@ include file="body.jsp"%>  
<%@ include file="tail.jsp"%>  
//第二种：<jsp:include>动作元素：当JSP页面被请求时引入指定文件  
<%@ page contentType="text/html; charset=GB2312" language="java" errorPage=""%>  
<jsp:include page="head.jsp"/>  
<jsp:include page="body.jsp"/>  
<jsp:include page="tail.jsp"/>  
 
 
//第二种方法可以很方便的用<jsp:param>来向所包含页传递参数，方法如下：  
<%@ page contentType="text/html; charset=GB2312" language="java" errorPage=""%>  
<jsp:include page="head.jsp"/>  
<jsp:include page="body.jsp">  
<jsp:param name="uid" value="username"/>  
<jsp:param name="pwd" value="password"/>  
</jsp:include>  
<jsp:include page="tail.jsp"/>
