Change the file Suffix of JSP

Today I have nothing to worry about. I suddenly thought of a problem. Can I replace the suffix for accessing JSP files with my own suffix? After some debugging, I finally succeeded. Hahaha. So happy .....
First, configure
<Servlet>
<Servlet-name> testsuffix </servlet-name>
<Servlet-class> mytest. TestSuffix </servlet-class>
</Servlet>
<Servlet-mapping>
<Servlet-name> testsuffix </servlet-name>
<Url-pattern> *. br </url-pattern>
</Servlet-mapping>

Write the page redirection in SERVLET ..

String uri = request. getRequestURI ();
Uri = uri. replaceFirst (". br", ". jsp ");

RequestDispatcher rd = request. getRequestDispatcher (uri );
Rd. forward (request, response );

Hahaha. You can access the previous JSP file through *. br.
