1.原始jsp模板
查看初始jsp创建模板：File---Setting---Editor---File and Code Templates---Other---Jsp files---JspFile.jsp，可在⑤处重新定义jsp模板，编写完成后，Apply，OK，下次在新建jsp文件时，即可建立所定义模板的jsp页面。
初始jsp模板代码如下：
<%--
Created by IntelliJ IDEA.
User: ${USER}
Date: ${DATE}
Time: ${TIME}
To change this template use File | Settings | File Templates.
--%>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>#[[$Title$]]#</title>
</head>
<body>
#[[$END$]]#
</body>
</html>
完整版的jsp模板代码：
<%--
Created by IntelliJ IDEA.
User: ${USER}

To change this template use File | Settings | File Templates.
--%>
<%@ page language="java" contentType="text/html; charset=utf-8" pageEncoding="utf-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<html>
<head>
<base href="<%=basePath %>" />
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Insert title here</title>
</head>
<body>
</body>
</html>
