Everything used to work before upgrading. I have upgraded to Spring framework 5.3 and updated configuration file . I am getting FineNotFound error when accessing contextRoot(index.html) or any other requests.
Web.exml

<servlet-name>abcd</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>

<servlet-mapping>

<url-pattern>*.html</url-pattern>

When trying to access localhost:9080/abcd - it is redirecting to localhost:9080/abcd/index.html which is correct but getting FileNotFoundErore.javax.servlet.ServletException: java.io.FileNotFoundException: SRVE0190E: File not found:
/index.html at
Whether I keep <prop key="index.html">homeController</prop> or remove it. Result is same.
