Question

当我使用弹簧云涡轮机时我配置了涡轮机

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

我不知道 clusterNameExpression 是什么意思

当我启动turbine服务器时，日志为

我开始两个具有不同端口的相同服务，但turbine显示器仅限于默认端口;

如何配置涡轮机来处理所有服务？。

请参阅文档：http://projects.spring.io/spring-cloud/docs/1.0.1/spring-cloud.html#_turbine

clusterNameExpression是一个Spring Expression Language表达式，用于从InstanceInfo获取群集名称的位置。默认值为appName。我不会改变clusterNameExpression。

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

您需要在Turbur网址/turbine.stream?cluster=<clustername>中添加clusterConfig中的群集名称。

spring-cloud-turbine clusterNameExpression配置是什么意思？
