首先，我想说我搜索了我的问题并提出了建议，但这对我没有帮助。
我的来源如下：
@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

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.

在大多数答案中建议只添加
@Bean
public RequestContextListener requestContextListener() {
return new RequestContextListener();
}
但是你可以看到这个建议已经应用了。
您能帮我执行其他服务的身份验证请求吗？
答案 0 :(得分：0)
当我更正@HystrixCommand注释参数时问题消失了：
@HystrixCommand(groupKey = "somethingProxy", commandKey = "retrieveSomething", ignoreExceptions = {
IllegalArgumentException.class }, fallbackMethod = "reliable", commandProperties = {
@HystrixProperty(name = "execution.isolation.strategy", value = "SEMAPHORE") })
public String hello() {
