Eureka发现客户端无法启动

Eureka配置如下：

1、Eureka Server

spring:
application:
name: eureka-server
server:
port: 1001
eureka:
instance:
hostname: 127.0.0.1
client:
register-with-eureka: false
fetch-registry: false
service-url:
defaultZone: http://localhost:${server.port}/eureka/

2、Eureka Discovery Client

spring:
application:
name: eureka-member-server
server:
port: 2001
eureka:
client:
service-url:
defaultZone: http://localhost:1001/eureka/

出现的问题

Eureka Server 端可以正常启动，而Eureka Discovery Client 端启动后立马停止，无法启动，控制台也没有报异常。

解决方法

给Eureka Discovery Client 端添加web模块的起始依赖：

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