It's from import org.springframework.security.authentication.AuthenticationManager; import org.springframework.security.authentication.UsernamePasswordAuthenticationToken;

TomásOP•3d ago

TomásOP•3d ago

    public static AuthenticationManager authenticationManager(AuthenticationConfiguration authenticationConfiguration) throws Exception {
        return authenticationConfiguration.getAuthenticationManager();
    }

 @Bean
    public static AuthenticationManager authenticationManager(AuthenticationConfiguration authenticationConfiguration) throws Exception {
        return authenticationConfiguration.getAuthenticationManager();

interesting

TomásOP•3d ago

the register end point works

ayylmao123xdd•3d ago

do you have more than one authentication provider or authentication configuration

TomásOP•3d ago

ayylmao123xdd•3d ago

@Bean
AuthenticationManager myAuthenticationManager(UserDetailsService userDetailsService, PasswordEncoder passwordEncoder) {
    DaoAuthenticationProvider provider = new DaoAuthenticationProvider();
    provider.setUserDetailsService(userDetailsService);
    provider.setPasswordEncoder(passwordEncoder);
    return provider::authenticate;
}

@Bean
AuthenticationManager myAuthenticationManager(UserDetailsService userDetailsService, PasswordEncoder passwordEncoder) {
    DaoAuthenticationProvider provider = new DaoAuthenticationProvider();
    provider.setUserDetailsService(userDetailsService);
    provider.setPasswordEncoder(passwordEncoder);
    return provider::authenticate;
}

try this

TomásOP•3d ago

** APPLICATION FAILED TO START ** Description: Field userDetailsService in ecomerce.api.infra.security.SecurityConfigurations required a bean of type 'org.springframework.security.core.userdetails.UserDetailsService' that could not be found. Action: Consider defining a bean of type 'org.springframework.security.core.userdetails.UserDetailsService' in your configuration.

ayylmao123xdd•3d ago

you need to define user details service bean for testing purposes do this

TomásOP•3d ago

User details service class is provided by spring

ayylmao123xdd•3d ago

 @Bean
    public UserDetailsService userDetailsService() {
          return new InMemoryUserDetailsManager();
    }

 @Bean
    public UserDetailsService userDetailsService() {
          return new InMemoryUserDetailsManager();
    }

try this

TomásOP•3d ago

i dont have any erros anymore when i try to login

TomásOP•3d ago

ayylmao123xdd•3d ago

😱 crazy right you have to define your own user details service though cuz the code i pasted is for testing
