Answer 1

问题出在您的客户端，即股票服务的application.yml。您需要按照此处所述更改它。

第 1 步：从 application.yml 中删除以下属性

eureka: client: register-with-eureka: false fetch-registry: false service-url: default-zone: http://localhost:8302/

实例： 主机名： 本地主机

第 2 步：将其添加到 application.yml 中

eureka: client: serviceUrl: defaultZone: http://localhost:8302/eureka/

这可能会解决您的问题。

Answer 2

• 当前线程。

您还应该在客户端应用程序中将以下属性从 false 更改为 true.yml 文件-

尤里卡： 客户：向尤里卡注册：真

似乎，在您的客户端配置中它是错误的。
