【问题描述】：

这就是我的 pom.xml 的样子

</project>

这就是我的主类的样子

@SpringBootApplication @EnableDiscoveryClient @EnableFeignClients @EnableCircuitBreaker @EnableHystrixDashboard 公共类应用程序 公共静态 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=问候服务 service.message-service.id=消息服务 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 时，流似乎生成如下

平：

平：

但是，即使在多次刷新并尝试多次点击 url 之后，仪表板似乎仍然卡在这一点上。

我错过了什么？

【参考方案1】：

尝试添加proxyStreamAllowList，在application.properties中添加这个-

hystrix.dashboard.proxyStreamAllowList = "*"
