Differences from JSP: Include

<% @ Include file = "A. jsp" %>	<JSP: Include page = "A. jsp"/>
Static inclusion: content is embedded into the page before the JSP page is converted into a servlet, and then compiled and run.	Dynamic inclusion. During running, the statement is dynamically compiled and loaded only when a request is sent and executed.
Parameter is not allowed	Parameters can be included, such as: <JSP: Include page = "A. jsp? B = 1 & C = 2 "/>
The contained page is consistent with the request object that contains the page.	The contained page is inconsistent with the request object that contains the page. However, the request that contains the page can obtain all the values that can be obtained by the request that contains the page.

<% @ Include file = "A. jsp" %> only one class file is generated.

<JSP: Include page = "A. jsp"/> multiple class files are generated.

<% @ Include file = "A. jsp" %> common
