这就是我的 pom.xml 的样子

这就是我的主要课程的样子
@SpringBootApplication
@EnableDiscoveryClient
@EnableFeignClients
@EnableCircuitBreaker
@EnableHystrixDashboard
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
这就是我的应用程序属性的样子
spring.application.name=greetings-service
service.message-service.id=messages-service
management.endpoints.web.exposure.include=*
这就是我的控制器的样子
@RestController 公共类 GreetingController {
@Autowired
public GreetingsService greetingsService;
@HystrixCommand(fallbackMethod = "defaultMessage")
@RequestMapping("/greeting/{id}")
public Greeting findMyGreetingMessage(@PathVariable Long id) {
Greeting greeting = new Greeting();
greeting.setMessage(greetingsService.getMessage(id));
return greeting;
}
public Greeting defaultMessage(Long id){
Greeting greeting = new Greeting();
greeting.setMessage("Message service seems to be broken");
return greeting;
}
}
当我检查 URL http://localhost:8082/actuator/hystrix.stream流似乎生成如下

但是，即使在多次刷新它并尝试多次点击该 url 之后，仪表板似乎仍停留在这一点上。
我在这里想念什么？
