pom.xml添加依赖

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

eureka的application.yml配置如下：

server:
  port: 8001
# 安全认证的配置
security:
  basic:
    enabled: true
  user:
    name: root  # 用户名
    password: root   # 用户密码
---
spring:
  application:
    name: cloud-discovery-eureka
  profiles: peer1
server:
  port: 10001
eureka:
  instance:
    hostname: peer1
  client:
    register-with-eureka: false
    fetch-registry: false
    serviceUrl:
      defaultZone: http://root:root@peer2:10002/eureka/,http://root:root@peer3:10003/eureka/

spring:
  application:
    name: cloud-discovery-eureka
  profiles: peer2
server:
  port: 10002
eureka:
  instance:
    hostname: peer2
  client:
    register-with-eureka: false
    fetch-registry: false
    serviceUrl:
      defaultZone: http://root:root@peer1:10001/eureka/,http://root:root@peer3:10003/eureka/

spring:
  application:
    name: cloud-discovery-eureka
  profiles: peer3
server:
  port: 10003
eureka:
  instance:
    hostname: peer3
  client:
    register-with-eureka: false
    fetch-registry: false
    serviceUrl:
      defaultZone: http://root:root@peer1:10001/eureka/,http://root:root@peer2:10002/eureka/

服务提供者的application.yml配置如下：

eureka:
  instance:
    prefer-ip-address: true
    # 此处，preferIpAddress不设置或者设为false，不能设为true，否则影响turbine的测试。
    # turbine存在的问题：eureka.instance.hostname一致时只能检测到一个节点，会造成turbine数据不完整
    hostname: feign
  client:
    service-url:
      defaultZone: http://root:root@localhost:8001/eureka/

补充peer1、peer2、peer3的由来
修改C:\Windows\System32\drivers\etc\hosts文件

127.0.0.1 peer1
127.0.0.1 peer2
127.0.0.1 peer3

命令行(cmd)运行:

ipconfig /flushdns #清除DNS缓存内容。
