Spring cloud 什么'；s代表spring cloud涡轮机ClusterName表达式配置的意思是什么？

当我使用弹簧云涡轮时 我配置了涡轮机

turbine:
  clusterNameExpression: new String("default")
  appConfig: crm,hystrix

我不知道clusterNameExpression是什么意思

当我启动

涡轮机

服务器时，日志是

我启动了两个具有不同端口的相同服务，但

涡轮机

监视器仅支持默认服务

如何配置风机以支持所有服务？

请查看文档：

clusterNameExpression

是一个Spring表达式语言表达式，用于从何处获取集群名称。默认值为

appName

。我不会改变

clusterNameExpression

您需要设置turbine.aggregator.clusterConfig=CRM，HYSTRIX

您需要将clusterConfig中的集群名称添加到turbine url

/turbine.stream？cluster=
