SpringBoot OAuth2 Client Google RequestMapping not working in RestController - spring-boot

Question

I am trying to build a SpringBoot OAuth2 Application but stuck with initiating the next POST request of access_token.
This is my code https://github.com/sangeeta-p-shetty/springboot_oauth2_google.git
It runs on http://localhost:8080/security. Currently it successfully redirects to Google and on Sign In redirects to the Redirect URL
Primarily, I am stuck at 3 areas:
#RequestMapping in #RestController is not working.
As RequestMapping is not working, the sample code even though successfully authorizes I am not able to initiate the next POST request of AccessToken. Wanted guidance on how to capture the response from Google and initiate a new request.
I wanted to redirect to OAuth2 only if specific URL is hit in the application. Currently Redirection is happening by launch of context. i.e http://localhost:8080/security
SecurityConfig.java
package com.google.config;
import ....;
#Configuration
#EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
#Override
protected void configure(HttpSecurity http) throws Exception {
http
// only disable these during testing or for non-browser clients
.cors().disable()
.csrf().disable()
.authorizeRequests()
.anyRequest().authenticated()
.and()
.oauth2Login()
.loginPage("/oauth2/authorization/google")
.authorizationEndpoint()
.authorizationRequestResolver(
new CustomAuthorizationRequestResolver(
clientRegistrationRepository(), "/oauth2/authorization"));
}
}

SpringBootApplication class

#SpringBootApplication
#ComponentScan("com.google")
public class OidcExampleApp {
public static void main(String[] args) {
SpringApplication.run(OidcExampleApp.class, args);
}
}
AppController.java
Currently in the github code, this class is not included. But below is the intended code which does not seem to get called.
package com.google.controller;
import ...;
#RestController
public class AppController {
#RequestMapping(value="/welcome") // here even If I give value="/welcome.html") it does not work
public String getHi() {
System.out.println("End Point hit*************************************");
return "Hi";
}
}
