Eureka Client 演示

Eureka Client 可以向 Eureka Server 中注册自己

导入依赖

注意依赖换成了 Eureka 客户端依赖

配置文件

application.yml

spring:
  application:
    # 如果没有配置，默认名称 UNKNOWN
    name: demo

eureka:
  client:
    service-url:
      # 下面信息也是默认值
      defaultZone: http://localhost:8761/eureka/

spring.application.name

eureka.client.service-url.defaultZone

注意

如果要变更 Eureka Server 的注册地址的端口号，只修改 server.port 是不够的，还要保证 eureka.client.service-url.defalutZone 一致

eureka:
  client:
    # 因为当前项目为服务，不需要向服务注册自己，默认为 true
    register-with-eureka: false
    # 因为当前为非集群版 eureka，所以不需要同步其他节点数据
    fetch-registry: false
    # 当 server.port 配置不是 8761 时需要配置内容
    service-url:
      defalutZone: http://localhost:8088/eureka/

# 如果不配置8761，还需要配置 defaultZone 修改端口
server:
  port: 8088
