创建名为“scopedTarget.oauth2ClientContext”的 bean 时出错：范围“会话”对于当前线程不活动；

Question

首先我想说的是，我用谷歌搜索了我的问题并采纳了建议，但对我没有帮助。

我的来源是这样的：

@SpringBootApplication
@EnableEurekaClient
@RibbonClient(name = "say-hello"/*, configuration = RibbonConfig.class*/)
@EnableAutoConfiguration
@EnableOAuth2Sso
public class HelloWorldStarter {

    public static void main(String[] args) {
        SpringApplication.run(HelloWorldStarter.class, args);
    }

    @Bean
    public RequestContextListener requestContextListener() {
        return new RequestContextListener();
    }


    @RestController
    @EnableDiscoveryClient
    @EnableCircuitBreaker
    public static class HelloWorldController {
        @Autowired
        private RestTemplate restTemplate;
        @Autowired
        private OAuth2RestTemplate oAuth2RestTemplate;
        @Autowired
        private DiscoveryClient discoveryClient;

        @GetMapping("/helloWorld")
        @HystrixCommand(fallbackMethod = "reliable")
        public String hello() {
            //String response = restTemplate.getForObject("http://localhost:8082/h/hello?name=World", String.class);
            try {
                return this.oAuth2RestTemplate.getForObject("http://hello-service/h/hello?name=World", String.class);
            } catch (Exception e) {
                e.printStackTrace();
                return null;
            }
        }

        public String reliable() {
            return "Could not get response from service";
        }
    }

    @org.springframework.context.annotation.Configuration
    public static class Configuration {
        @Bean
        @LoadBalanced
        RestTemplate restTemplate() {
            return new RestTemplate();
        }

        @Bean
        @ConfigurationProperties("security.oauth2")
        public ClientResources clientResources() {
            return new ClientResources();
        }

        @Autowired
        private OAuth2ClientContext oAuth2ClientContext;

        @Bean
        @LoadBalanced
        public OAuth2RestTemplate oAuth2RestTemplate() {
            return new OAuth2RestTemplate(clientResources().getClient(), oAuth2ClientContext);
        }

        class ClientResources {

            @NestedConfigurationProperty
            private AuthorizationCodeResourceDetails client = new AuthorizationCodeResourceDetails();

            @NestedConfigurationProperty
            private ResourceServerProperties resource = new ResourceServerProperties();

            public AuthorizationCodeResourceDetails getClient() {
                return client;
            }

            public ResourceServerProperties getResource() {
                return resource;
            }
        }
    }
}

application.yml：

spring:
  application:
    name: hello-world-service
server:
  port: 8081
  servlet:
    context-path: /hw
eureka:
  client:
    serviceUrl:
      defaultZone: http://localhost:8761/eureka
  instance:
    preferIpAddress: true

security:
  oauth2:
    client:
      client-id: acme
      client-secret: acmesecret
      access-token-uri: http://localhost:8080/oauth/token
      user-authorization-uri: http://localhost:8080/oauth/authorize
    resource:
      user-info-uri: http://localhost:8080/me

logging:
  level:
    org.springframework.security: DEBUG
    org.springframework.web: DEBUG

当我调用/helloWorld Rest 方法时，会发生以下错误：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'scopedTarget.oauth2ClientContext': Scope 'session' is not active for the current thread; consider defining a scoped proxy for this bean if you intend to refer to it from a singleton; nested exception is java.lang.IllegalStateException: No thread-bound request found: Are you referring to request attributes outside of an actual web request, or processing a request outside of the originally receiving thread? If you are actually operating within a web request and still receive this message, your code is probably running outside of DispatcherServlet/DispatcherPortlet: In this case, use RequestContextListener or RequestContextFilter to expose the current request.

在大多数答案建议中添加

@Bean
public RequestContextListener requestContextListener() {
    return new RequestContextListener();
}

但正如您所见，此建议已被采纳。

你能帮我对另一个服务执行经过身份验证的请求吗？

当我更正@HystrixCommand注解参数后问题消失了：

    @HystrixCommand(groupKey = "somethingProxy", commandKey = "retrieveSomething", ignoreExceptions = {
            IllegalArgumentException.class }, fallbackMethod = "reliable", commandProperties = {
            @HystrixProperty(name = "execution.isolation.strategy", value = "SEMAPHORE") })
    public String hello() {
