Field authenticationManager in *** required a bean of type 'org.springframework.security.authentication.AuthenticationManager' that could not be found

Question

I have following class:

@Configuration
@EnableAuthorizationServer
public class AuthServerConfig extends AuthorizationServerConfigurerAdapter {
    @Autowired
    private AuthenticationManager authenticationManager;

    @Override
    public void configure(AuthorizationServerSecurityConfigurer oauthServer) throws Exception {
        oauthServer.tokenKeyAccess("permitAll()")
                .checkTokenAccess("isAuthenticated()");
    }

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

    @Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
        endpoints.authenticationManager(authenticationManager);
    }
}

and following dependencies:

dependencies {
    compile('org.springframework.boot:spring-boot-starter-web')
    testCompile('org.springframework.boot:spring-boot-starter-test')
    compile 'org.springframework.security.oauth:spring-security-oauth2:2.3.2.RELEASE'    
}

When I start application I see following log:

Description:

Field authenticationManager in com.my.sso.server.AuthServerConfig 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.


Process finished with exit code 1

What wrong with my configuration?

Actually I try to repeat ecxample from http://www.baeldung.com/sso-spring-security-oauth2 and I don't see explicit declaration of this bean

Answer 1

Need to add

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.authentication.AuthenticationManager;
@Configuration
public class UserSecurityConfig  extends WebSecurityConfigurerAdapter {
     @Bean
    public AuthenticationManager getAuthenticationManager() throws Exception {
        return super.authenticationManagerBean();
    }
}

Answer 2

Seems that I've found the solution to the issue, besides that we need add spring-boot-starter-security dependency, starting from spring-security 5.x bean of type AuthenticationManager is not autoconfigured for you, you need to define one by yourself see: https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-2.0-Migration-Guide#authenticationmanager-bean
