如何访问hystrix仪表板？

Question

我在Spring Boot应用程序中添加了以下依赖项：

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-netflix-hystrix-dashboard</artifactId>
    <version>2.1.3.RELEASE</version>
</dependency>

并用：标记配置类>

@EnableHystrixDashboard
我尝试访问http://localhost:8080/hystrix（我也尝试了http://localhost:8081/hystrix）

我看到：

Whitelabel错误页面此应用程序没有针对/ error，因此您将其视为备用。

[Mon Nov 11 21:47:56 MSK 2019发生意外错误（type = Not找到，状态为404）。无可用消息

在启动过程中，我看到以下消息：

P.S。

在调试中，我看到这些方法被调用，但是无论如何我都看到错误：

当我访问URL时也看到以下响应：http://localhost:8080/actuator/hystrix.stream

我在Spring Boot应用程序中添加了以下依赖项：org.springframework.cloud

Hystrix搜索@HystrixCommand批注，以显示有关您要监视的服务的数据，并且它需要执行器端点。您将需要这两个依赖项：
