用jdbc数据源连接ClientRegistrationService

Question

I could successfully set the jdbc datasource to Spring OAuth2 using the following configuration. However I am struggling to wire ClientRegistrationService while it was easy to wire ClientDetailsService .

@Configuration
@EnableAuthorizationServer
protected static class OAuth2AuthorizationConfig extends AuthorizationServerConfigurerAdapter {

    @Autowired
    private AuthenticationManager authenticationManager;

    @Autowired
    private DataSource dataSource;

    @Override
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
        clients.jdbc(dataSource);
    }
    .....
}

Here is what I tried

1. Below code fails to find the ClientDetailsService is not instanceof or of assignableFrom JdbcClientDetailsService or ClientRegistrationService

   @Controller public class ClientPortalApplication {

    private ClientRegistrationService clientService; @Autowired public void setClientDetailsService(ClientDetailsService clientDetailsService) { if (clientDetailsService instanceof JdbcClientDetailsService)) { clientService = (ClientRegistrationService) clientDetailsService; } } ...... 

   }

2. Below code wiring fails on finding a bean of type ClientRegistrationService

:

@Controller
public class ClientPortalApplication {

    @Autowired
    private ClientRegistrationService clientService;

    ......
}

The ClientDetailsService created in yout AuthorizationServerConfigurerAdapter is not a bean therefore can't be injected. A solution is to create a bean JdbcClientDetailsService inject it in the AuthorizationServerConfigurerAdapter and you will be able to inject it anywhere else:

@Configuration
public class MyConfiguration {
    @Autowired
    private DataSource dataSource;
    @Bean
    public JdbcClientDetailsService jdbcClientDetailsService() {
        return new JdbcClientDetailsService(dataSource);
    }

    @Configuration
    @EnableAuthorizationServer
    protected class OAuth2AuthorizationConfig extends AuthorizationServerConfigurerAdapter {
        @Autowired
        private JdbcClientDetailsService jdbcClientDetailsService;
        public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
            clients.withClientDetails(jdbcClientDetailsService);
        }
    }    
}
