Spring Security + Google OAuth2登录：访问令牌为空？

Question

我从默认的Spring Security OAuth2登录实现（不使用Spring Boot）中收到此错误：

[invalid_token_response]尝试检索OAuth 2.0访问令牌响应时发生错误：提取类型[class org.springframework.security.oauth2.core.endpoint.OAuth2AccessTokenResponse]和内容类型[application / json; charset = utf]的响应时出错-8];嵌套异常是org.springframework.http.converter.HttpMessageNotReadableException：读取OAuth 2.0访问令牌响应时出错：null;嵌套异常是java.lang.NullPointerException

情节是：我去任何受保护的页面，它重定向到谷歌“选择一个帐户”thingy，我选择帐户和爆炸，重定向到/登录？错误显示上面提到的文本。

Spring Security配置：

@Configuration
@EnableWebSecurity()
@PropertySource("classpath:application.properties")
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {   

    @Override
    protected void configure(HttpSecurity http) throws Exception {      
        http    
            .csrf().disable()
            .authorizeRequests()
                .antMatchers("/tlog/**").authenticated()                
            .and().oauth2Login();
    }

    @Bean
    public OAuth2AuthorizedClientService authorizedClientService() {      
        return new InMemoryOAuth2AuthorizedClientService(clientRegistrationRepository());
    }

    @Bean
    public OAuth2AuthorizedClientRepository authorizedClientRepository(OAuth2AuthorizedClientService authorizedClientService) {
        return new AuthenticatedPrincipalOAuth2AuthorizedClientRepository(authorizedClientService);
    }


    @Bean
    public ClientRegistrationRepository clientRegistrationRepository() {        
        return new InMemoryClientRegistrationRepository(googleClientRegistration());        
    }   

    private ClientRegistration googleClientRegistration() {
        return CommonOAuth2Provider.GOOGLE.getBuilder("google")
            .clientId("XXX")
            .clientSecret("ZZZ")
            .build();
    }

}

我在这里错过了什么？找不到任何体面的教程，不使用真正有用的Spring Boot。
