Envisagez de définir un bean de type 'org.springframework.security.authentication.AuthenticationManager' dans votre configuration

Question

J'ai suivi quelques suggestions mentionnées ici, mais cela n'a pas fonctionné pour moi. Par conséquent, en posant la question ici

1. Comment injecter AuthenticationManager en utilisant Java dans un filtre personnalisé
2. Spring avait besoin d'un bean de type 'AuthenticationManager'

Quelqu'un pourrait-il me guider, quel est le problème et comment y remédier?

Erreur:

Description:

Field authenticationManager in com.techprimers.security.springsecurityauthserver.config.AuthorizationServerConfig required a bean of type 'org.springframework.security.authentication.AuthenticationManager' that could not be found.


Action:

Consider defining a bean of type 'org.springframework.security.authentication.AuthenticationManager' in your configuration.

AuthorizationServerConfig.Java

@Configuration
@EnableAuthorizationServer
public class AuthorizationServerConfig extends AuthorizationServerConfigurerAdapter {

    @Autowired
    private AuthenticationManager authenticationManager;

    @Override
    public void configure(AuthorizationServerSecurityConfigurer security) throws Exception {

        security.tokenKeyAccess("permitAll()")
                .checkTokenAccess("isAuthenticated()");
    }


    @Override
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
        clients
                .inMemory()
                .withClient("ClientId")
                .secret("secret")
                .authorizedGrantTypes("authorization_code")
                .scopes("user_info")
                .autoApprove(true);
    }


    @Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {

        endpoints.authenticationManager(authenticationManager);
    }
}

ResourceServerConfig.Java

@EnableResourceServer
@Configuration
public class ResourceServerConfig extends WebSecurityConfigurerAdapter {


    @Autowired
    @Qualifier("authenticationManagerBean")
    private AuthenticationManager authenticationManager;
    @Autowired
    private UserDetailsService customUserDetailsService;

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

        http.requestMatchers()
                .antMatchers("/login", "/oauth/authorize")
                .and()
                .authorizeRequests()
                .anyRequest()
                .authenticated()
                .and()
                .formLogin()
                .permitAll();
    }


    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.parentAuthenticationManager(authenticationManager)
                .userDetailsService(customUserDetailsService);
    }
}

La référence de code tirée de https://github.com/TechPrimers/spring-security-oauth-mysql-example , uniquement la version parent Spring Boot mise à jour vers 2.0.4.RELEASE, les choses ont commencé à se casser.

Answer 1

just add this to the AuthenticationManagerBuilder

@Override
@Bean
public AuthenticationManager authenticationManagerBean() throws Exception {
    return super.authenticationManagerBean();
}

and in your controller where you need to use it add this :

 @Autowired
    private AuthenticationManager authenticationManager;
