how do I update my application to remove the dependency cycle between beans

Question

I am getting a cycle dependency error on my spring authentication service class and Security Configuration class.

***************************
APPLICATION FAILED TO START
***************************

Description:

The dependencies of some of the beans in the application context form a cycle:

┌─────┐
|  securityConfiguration defined in file [C:\Users\SRO\Documents\repositories\blackjack\blackjack-backend\target\classes\com\app\blackjack\configurations\SecurityConfiguration.class]
↑     ↓
|  authenticationService defined in file [C:\Users\SRO\Documents\repositories\blackjack\blackjack-backend\target\classes\com\app\blackjack\services\AuthenticationService.class]
└─────┘


Action:

Relying upon circular references is discouraged and they are prohibited by default. Update your application to remove the dependency cycle between beans. As a last resort, it may be possible to break the cycle automatically by setting spring.main.allow-circular-references to true.

I'm making a simple sign up + login functionality for my spring project and the only way I've learned, so far, how to login a user is by injecting the authentication manager in the service class to authenticate the login information.

My guess is that is interfering with the Security Configuration's @bean annotation but I'm not sure how to fix that. Any help?

SecurityConfiguration

@Configuration

    private final AuthenticationService authservice;
    private final PasswordEncoder passwordEncoder;
    
     @Bean(BeanIds.AUTHENTICATION_MANAGER)
     @Override
     public AuthenticationManager authenticationManagerBean() throws Exception {
         return super.authenticationManagerBean();
     }

     @Override
     protected void configure(HttpSecurity http) throws Exception {
            http

                        .permitAll()
                    .anyRequest()
                    .authenticated().and()
                    .formLogin();
        }
     
     protected void configureGlobal(AuthenticationManagerBuilder authenticationManager) throws Exception {
         authenticationManager.userDetailsService(authservice)
         .passwordEncoder(passwordEncoder.bCryptPasswordEncoder());
     }
}

        }

    }
    
    public ResponseEntity<String> login(LoginRequest loginRequest) {
        
        org.springframework.security.core.Authentication authenticate = null;
        
        try {
        authenticate = authenticationManager.authenticate
                    (new UsernamePasswordAuthenticationToken(loginRequest.getEmail(), loginRequest.getPassword()));
            } catch (Exception e ) {
            return new ResponseEntity("FAILED", HttpStatus.BAD_REQUEST );
            }
       
            return new ResponseEntity<String>("SUCCESS", HttpStatus.ACCEPTED);
    }
