【springcloudalibaba】-微服務AB注入到 EurekaServer集羣中（zcw-demo）【十】

前言

本篇博客主要是向大家介紹，怎麼把微服務AB注入到我們集羣中去，希望通過本篇博客的介紹，能給你帶來幫助，

微服務註冊到EurekaServer集羣中

1.修改YML文件

• 微服務A
  

server:
  port: 8077

spring:
  application:
    name: cloud-provider-payment-zcw-service
  datasource:
    type: com.alibaba.druid.pool.DruidDataSource   # 當前數據源操作類型
    driver-class-name: org.gjt.mm.mysql.Driver
    url: jdbc:mysql://localhost:3306/zcw20200509?useUnicode=true&characterEncoding=utf-8&useSSL=false
    username: root
    password: root

eureka:
  client:
    #表示是否將自己祖冊到EurekaServer默認爲true
    register-with-eureka: true
    #是否從EurekaServer抓取已有的註冊信息，默認爲true，單節點無所謂，集羣必須設置爲true，才能配合ribbon負載均衡
    fetchRegistry: true
    serviceUrl:
      #defaultZone:  http://server1:7001/eureka/
      defaultZone:  http://server2:7008/eureka/,http://server1:7001/eureka/
mybatis:
  mapper-locations: classpath:mapper/*.xml
  type-aliases-package: com.zcw.springcloud.entities # 所有entity別名類所在包

• 微服務B
  

server:
  port: 8098

spring:
  application:
    name: cloud-order-service
eureka:
  client:
    register-with-eureka:  true
    fetch-registry: true
    service-url:
#      defaultZone: http://localhost:7001/eureka/
      defaultZone:  http://server2:7008/eureka/,http://server1:7001/eureka/

2.測試

• 啓動各個組件
  
  
  
  

• 查看註冊中心的數據展示
  
  

3.訪問接口

• 根據上面的問題，進行修改bug,我仔細看了一下上面的問題，查找自己的代碼，
  
  之前修改了，配置文件中的端口號，
  

成功
