Spring Cloud - HystrixCommand -如何正确启用共享库

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-netflix-hystrix</artifactId>
</dependency>

@Service
public class MyService {
    @HystrixCommand(fallbackMethod = "fallbackMethod")
    public String myMethod() {
        // 服务逻辑
    }

    public String fallbackMethod() {
        // 降级处理逻辑
    }
}

hystrix:
  command:
    default:
      execution.isolation.thread.timeoutInMilliseconds: 5000

@SpringBootApplication
@EnableCircuitBreaker
public class MyApplication {
    public static void main(String[] args) {
        SpringApplication.run(MyApplication.class, args);
    }
}
