我解决的方式就是使用他拉问题中提供的答案就可以解决，
@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(); } //....... }
下面是错误提示：
