我正在尝试使用Netflix eureka服务发现和hystrix断路器构建简单的Spring Cloud 应用程序 .
Circuit Breaker Service:
@EnableCircuitBreaker
@SpringBootApplication
@EnableEurekaClient
public class PluralsightEurekaFastpassConsoleApplication {
public static void main(String[] args) {
SpringApplication.run(PluralsightEurekaFastpassConsoleApplication.class, args);
}
}

我试过Unable to connect to Command Metric Stream for Hystrix Dashboard with Spring Cloud
但问题仍然存在 .

这个问题没有提供足够的信息,所以最好的方法是确保:
Circuit Breaker Service 正在端口8088上运行
断路器服务中的 spring 启动 Actuator endpoints 确实已在
actuator
上下文路径下部署和访问 . 为了检查 Actuator 的实际位置,分析启动日志,如果没有关于已部署 endpoints 的信息,请将--debug
添加到微服务的应用程序启动中 .看起来第二步将揭示真正的问题 . 然后可以使用
management.context-path
设置 Actuator 上下文路径,或者应该自定义hystix仪表板
