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

Alright, so in recent versions of Spring it is not enough to simply add the bean in your configurer class, you actually need to do something else.

Whatever dependency missing to autowire or to tcreate a bean, has to be specified in the main class of your application. For your case, let's say your WebSecurityConfigurerAdapter is under the package "configure", do the folowing:

@SpringBootApplication
@ComponentScan({"controller", "services", "configure"}) // This is what you need
@EntityScan("com.my.sso.server.models")
public class YourApplicationMainClass { ...

Also, when adding and overriding the bean, make sure @Override is above @bean:

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

Answer 2

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 3

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

Answer 4

The missing class is in spring-security-core. Try adding this dependency:

compile ('org.springframework.boot:spring-boot-starter-security')
