    您已添加 

    <dependency>
  <groupId>org.springframework.cloud</groupId>
  <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
</dependency>

    此依赖项将应用程序配置为 client application .你需要 Eureka Server 在它基本上会运行的地方启动和运行 register

    默认端口,其中 Eureka Client Eureka服务器 8761 .因此,你得到了一个例外。

    还要检查应用程序是否支持 Discover services 或者,您可以通过引入以下属性来禁用客户端发现

    spring.cloud.discovery.enabled=false

    https://docs.spring.io/spring-cloud-netflix/docs/current/reference/html/

    另请查看上的教程 Eureka Netflix Client 和 Eureka Netflix Server . 这些都是微服务体系结构的基本组成部分,如果您对这些主题进行更多探索,您就会明白其中的道理。
