Answer 1

问题在于

server.port

和

management.server.port

不同。如果管理服务器在不同的端口上运行，您必须向 StackSaga 提及该端口。如果不这样做，StackSaga 将使用已启动的默认 Web 服务器端口。

由于您使用的是 StackSaga 客户端和 Eureka 客户端，您可以像下面这样进行配置。

#The port should be the same as that used for the management server.
eureka.instance.metadata-map.stacksagaManagementPort=2077
