Now, we will provide the created UserCache bean to AuthenticationProvider:

@Bean
public AuthenticationProvider authenticationProviderBean() {
     DaoAuthenticationProvider authenticationProvider = new              
     DaoAuthenticationProvider();
     authenticationProvider.setPasswordEncoder(passwordEncoder);
     authenticationProvider.setUserCache(userCache);
     authenticationProvider.
     setUserDetailsService(userDetailsService());
     return authenticationProvider;
}
