I have no problem with autowiring neo4j Repository in my @Controller file, but when trying to autowire same repository in shiro realm, i got below error, any help would be greately appreciated!

My classes and configurations:

ShiroPasswordDbRealm.java

@Component

public class ShiroPasswordDbRealm extends AuthorizingRealm {



    @Autowired

    private UserGraphRepository userGraphRepository;

    ...

UserGraphRepository.java

public interface UserGraphRepository extends GraphRepository<UserGraph>, RelationshipOperationsRepository<UserGraph>, CypherDslRepository<UserGraph> {



    UserGraph findByEmail(String email);

    ...

SecurityConfig.java

@Configuration

public class SecurityConfig {



    @Bean

    public Realm configureShiroPasswordDbRealm() {

        return new ShiroPasswordDbRealm();

    }



    @Bean(name = "securityManager")

    public DefaultWebSecurityManager configSecurityManager() {

        DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();

        ArrayList<Realm> realms = new ArrayList<Realm>();

        realms.add(configureShiroPasswordDbRealm());

        securityManager.setRealms(realms);

        return securityManager;

    }

    ...

Neo4jConfig.java

@Configuration

@EnableNeo4jRepositories(basePackages={"com.xxx.account.repository"})

public class Neo4jConfig extends Neo4jConfiguration {

...

Error i got:
