Eureka启动不起来

Question

SpringBoot是2.0.1.RELEASE SpringCloud是Finchley.RC1

客户端服务端分别引入了Eureka Discovery和Eureka Server

我服务端application.yml配置如下

eureka:
     client:
          service-url:
                defaultZone:  http://localhost:8761/eureka/
          register-with-eureka: false
     instance:
          preferIpAddress: true
          hostname: localhost
     server:
       enable-self-preservation: false
spring:
     application:
          name: server
server:
     port: 8761

我客户端application.yml配置如下

eureka:
     client:
          service-url:
                defaultZone:  http://localhost:8761/eureka/
spring:
     application:
          name: client

但是启动客户端启动不起来，一启动就结束，以下是客户端启动信息，也不报错，找不到原因

Answer 1

引入web模块

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

Answer 2

自动结束是因为没有bean，但是是成功的，可以加入spring-boot-starter-web 但是为什么是计算器名不清楚
