stack-overflow - Spring oauth2中的StackOverflowError与自定义ClientDetailsS​​ervice

Question

我自己实现了ClientDetailsS​​ervice:

@Service
public class JpaClientDetailsService implements ClientDetailsService {
    @Autowired
    private ClientRepository clientRepositoy;

    @Override
    public ClientDetails loadClientByClientId(String clientId) throws ClientRegistrationException {
        ClientDetails client = clientRepositoy.findOne(clientId);
        if (client == null) {
            throw new ClientRegistrationException(String.format("Client with id %s not found", clientId));
        }
        return client;
    }
}

ClientRepository 是一个标准的 JpaRepository。

我像这样配置了 AuthorizationServerConfigurerAdapter:

@Configuration
@EnableAuthorizationServer
@EnableResourceServer
public class OAuth2ServerConfig extends AuthorizationServerConfigurerAdapter {
    @Autowired
    private AuthenticationManager authenticationManager;

    @Autowired
    private ClientDetailsService clientDetailsService;

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

    @Override
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
        clients.withClientDetails(clientDetailsService);
    }
}

但是当我去 http://localhost:9999/oauth/authorize?response_type=code&client_id=lipton ，我得到一个
java.lang.StackOverflowError: null. Spring loops on com.sun.proxy.$Proxy81.loadClientByClientId(Unknown Source).
我不明白为什么。

Answer 1

我不明白为什么，但如果我直接注入(inject)我的 bean 而不是注入(inject)接口(interface)，它可以工作:

public class OAuth2ServerConfig extends AuthorizationServerConfigurerAdapter {
...
  @Autowired
  private JpaClientDetailsService clientDetailsService;
...

如果我使用 @Primary 注释来注释我的服务，它也可以工作:

@Service
@Primary
public class JpaClientDetailsService implements ClientDetailsService {
