为什么同样的eureka server 没报错， eureka cline 就报错了

我们看下 两个 依赖包都存在什么：

spring-cloud-starter-netflix-eureka-server

spirng eureka client 启动时报错：Completed shut down of DiscoveryClient_spring

spring-cloud-starter-netflix-eureka-client

spirng eureka client 启动时报错：Completed shut down of DiscoveryClient_依赖包_02

观察发现，两者相差什么，最后发现缺少了依赖

<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
