%>

<%@page info="作者:Ai<br> 时间:2018年5月24日23:06:36<br>" %>Get page information
该网页信息为:<%=getServletInfo()%>4. Use the include directive to include multiple jsp pages
When part of the content needs to be repeated, we can extract it separately, and all netizens who use this part use this jsp.
When the jsp is updated, the content of all pages that use the jsp will change.
<%@include file="logoTitle.jsp"%>
