JSP静态包含和动态包含的区别
jsp动态包含和静态包含实现的内容一样，但是实现的方式不同。
jsp静态包含<%@ include file="" %>
创建include1.jsp和include2.jsp
include1.jsp代码
<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%> <%@ include file="include2.jsp"%> <!DOCTYPE html> <html> <head> <meta charset="ISO-8859-1"> <title>Insert title here</title> </head> <body> this is include page 1 </body> </html>
include2.jsp代
<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%> <!DOCTYPE html> <html> <head> <meta charset="ISO-8859-1"> <title>Insert title here</title> </head> <body> this is include page 2 </body> </html>
运行结果：
如果是静态包含，则只会生成一个java文件
原因：因为include1.jsp要把include2.jsp内容完全引用，所有include1.jsp会和include2.jsp合成一个jsp，然后翻译成.java文件，最后编译运行。
jsp动态包含<jsp:include page=""></jsp:include>
创建Newfile1.jsp和NewFile2.jsp
Newfile1.jsp代码
<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%> <!DOCTYPE html> <html> <head> <meta charset="ISO-8859-1"> <title>Insert title here</title> </head> <body> <jsp:include page="/NewFile2.jsp"></jsp:include> this is newFile1 </body> </html>
Newfile2.jsp代码
<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%> <!DOCTYPE html> <html> <head> <meta charset="ISO-8859-1"> <title>Insert title here</title> </head> <body> this is newFile2 </body> </html>
运行结果：
如果是动态包含，，则会生成两个.java文件
