SpringCloud中一些基本配置

1：eureka集群：原则，相互注册即可

注意：

　　a:必须要有示例名，且必须相同

b:集群模式必须开启注册registerWithEureka: true，单机情况下这个是false

c:如果用域名，必须映射hosts

以下用两个节点做演示server1,server2

server-1:

server:
  port: 8080
eureka:
  server:
    #禁止自我保护,剔除无效服务
    enable-self-preservation: false
    #清理自我保护时间间隔 默认是60秒 单位毫秒 设定3s
    eviction-interval-timer-in-ms: 3000
  instance:
    hostname: eurekserveranode1
  client:
    #单机设置false,集群需要设置为true,负责找不到其他示例，无法相互注册
    registerWithEureka: true
    #要不要去注册中心获取其他服务的地址
    fetchRegistry: false
    serviceUrl:
      #erureka-server集群指向其他服务 
      defaultZone: http://eurekserveranode2:8081/eureka/
#集群EurekaServer的applicationname必须有且必须相同
spring:
  application:
    name: eureka-server

server2:

server:
  port: 8081
eureka:
  server:
    #禁止自我保护,剔除无效服务
    enable-self-preservation: false
    #清理自我保护时间间隔 默认是60秒 单位毫秒 设定3s
    eviction-interval-timer-in-ms: 3000
  instance:
    hostname: eurekserveranode2
  client:
    #单机设置false,集群需要设置为true
    registerWithEureka: true
    fetchRegistry: false
    serviceUrl:
      #集群指向另外地址
      defaultZone: http://eurekserveranode1:8080/eureka/
#集群EurekaServer的applicationname必须有且必须相同
spring:
  application:
    name: eureka-server

然后依次启动，在网页中访问：

http://127.0.0.1:8081/ 可以看到：注册到了8080

http://127.0.0.1:8080/ 可以看到：注册到了8081

eureka-client:

eureka:
  client:
    serviceUrl:
      defaultZone: http://eurekserveranode1:8080/eureka/,http://eurekserveranode2:8081/eureka/
server:
  port: 8758
spring:
  application:
    name: service-member

zuul:

eureka:
  client:
    serviceUrl:
      defaultZone: http://localhost:8080/eureka/
    #设置eureka-client多久拉取注册信息 默认30s
    registry-fetch-interval-seconds: 5
server:
  port: 8766
spring:
  application:
    name: service-zuul
zuul:
  routes:
    api-a:
      path: /api-member/**
      service-id: service-member
    api-b:
      path: /api-order/**
      service-id: service-order
