Content layout in a JSP

Reference: Https://stackoverflow.com/questions/10529963/what-is-the-best-way-to-create-jsp-layout-template

In the development of the front-end Web page, the site generally has a template page, to save the entire site The most basic style, and other pages are in this style to modify. This function can be implemented by tag in JSP.

Create a new Base.tag template page in the web-inf/tags/directory to save the newly created template:

<% @tag description= "Overall page template" pageencoding= "UTF-8"%>  <%@ taglib  prefix= "C"  uri= " Http://java.sun.com/jsp/jstl/core "%>  <% @attribute name=" num "rtexprvalue=" false "required=" true "%>  <% @attribute name= "header" fragment= "true" required= "true"%>  <% @attribute name= "Footer" fragment= "True" required= "true"%>      
In this template we define two replaceable parts: header,footer, a variable num.
The Sub-page uses this label as follows:
    <% @taglib prefix= "T" tagdir= "/web-inf/tags"%>            <t:base num= "abc" >            <jsp:attribute name= " Header ">      <title>Welcome</title>
