include.jsp
<%@ page contentType="text/html" pageEncoding="utf-8"%>
<html>
<head><title>frfrfr</title></head>

<h1>静态包含</h1>
<h3><%@ include file = "info.html"%></h3>
<h3><%@ include file = "info.jsp"%></h3>
<h3><%@ include file = "info.inc"%></h3>
</body>
</html>
info.html
<h2><font color = "red">info.html</font></h2>
info.ioc
<h2><font color = "blue">info.inc</font></h2>
info.jsp
<h2><font color = "blue">info.inc</font></h2>
静态包含直接替换。
动态包含：
der.jdp
<%@ page contentType="text/html" pageEncoding="utf-8"%>
<html>
<head><title>frfrfr</title></head>
<body>
<h1>动态包含</h1>
<jsp:include file = "info.html"/>
<jsp:include file = "info.jsp"/>
<jsp:include file = "info.inc"/>
</body>
</html>
demo.jsp
<%@ page contentType="text/html" pageEncoding="GBK"%>
<html>
<head><title>www.mldnjava.cn，MLDN高端Java培训</title></head>
<body>
<h1>动态包含操作</h1>
<%
String username = "lop" ;
%>
<jsp:include page="receive_param.jsp">
<jsp:param name="name" value="<%=username%>"/>
<jsp:param name="info" value="www.mldnjava.cn"/>
</jsp:include>
</body>
</html>
receive_param.jsp
<%@ page contentType="text/html" pageEncoding="GBK"%>
<h1>参数一：<%=request.getParameter("name")%></h1>
<h1>参数二：<%=request.getParameter("info")%></h1>
静态变量重复
demo4.jsp
<%@ page contentType="text/html" pageEncoding="GBK"%>
<html>
<head><title>yyy</title></head>
<body>
<%
int x = 100 ; // 变量重复
%>
<h1>demo04.jsp -- <%=x%></h1>
<%@include file="include.jsp"%>
</body>
</html>
include.jsp
<%
int x = 10 ;
%>
<h1>include.jsp -- <%=x%></h1>
这样会出错。
动态变量的重复：
<%@ page contentType="text/html" pageEncoding="GBK"%>
<html>
<head><title>www.mldnjava.cn，MLDN高端Java培训</title></head>
<body>
<%
int x = 100 ; // 变量重复
%>
<h1>include_demo04.jsp -- <%=x%></h1>
<jsp:include page="include.jsp"/>
</body>
</html>
动态包含变量名重复是可以的。
