springcloud服务注册服务总线配置服务调用简单使用

首先参考以下几个文档顺序完成相应的搭建，注意，除了eureka作为服务server引入jar其它全部作为client引入服务注册和发现的依赖，而对于config依赖只有配置中心的服务作为server，其它应用服务作为client

项目搭建参考文档：https://www.jianshu.com/p/65dfbb55779b
项目启动参考文档：https://blog.csdn.net/singlekingdom/article/details/91378831
服务注册发现保证服务之间不用频繁修改地址：https://www.cnblogs.com/luchangyou/p/7576552.html
配置中心：https://blog.51cto.com/12965378/2403913
rabbitMQ安装（配置的实时刷新）：https://www.cnblogs.com/sam-uncle/p/9050242.html 到计算管理中心启动rabbitmq服务到\rabbitmq_server-3.7.9\sbin 下执行命令启动管理页面 rabbitmq-plugins enable rabbitmq_management

执行完以上步骤后的工程结构如下：

configserver提供配置的配置中心并能够通过rabbitmq广播给各个服务刷新配置

eureka提供给各服务的服务注册和发现，便于服务之间调用不用知道ip端口，只需要知道服务名称即可

springcloudapi在此仅仅是提供服务之间交互的模型对象

springcloudconsumeruser8000服务调用方

springcloudprovideruser8001服务被调用方

以上描述的均是springcloud的子工程

启动类

@SpringBootApplication
@EnableDiscoveryClient
@EnableConfigServer
public class ConfigApplication {

    public static void main(String[] args) {
        SpringApplication.run(ConfigApplication.class, args);
    }
}

dev提供给其它服务用的配置 config-server-dev.yml

eureka:
  client:
    serviceUrl:
      defaultZone: http://localhost:8761/eureka
    instance:
      appname: 111网关服务1112修改了哦11166666ask
      prefer-ip-address: true
      lease-renewal-interval-in-seconds: 2
      lease-expiration-duration-in-seconds: 5

application.yml文件


server:
  port: 8888

eureka:
  client:
    register-with-eureka: false
    fetch-registry: false
    service-url:
      defaultZone: http://user:pass@localhost:8761/eureka

spring:
  application:
    name: config-server
  cloud:
    config:
      server:
        native:
#        必须写绝对路径，否则可能导致bus总线无法及时通过 /actuator/bus-refresh post请求及时刷新配置并通知所有的服务  （Content-Type application/json;charset=utf-8 此值必须设置）
          search-locations: E:/svn/springcloud/configserver/src/main/resources/config
    bus:
      enabled: true
      trace:
        enabled: true
  profiles:
    active: native
  rabbitmq:
    host: 127.0.0.1
    port: 5672
    username: guest
    password: guest
management:
  endpoints:
    web:
      exposure:
        include: bus-refresh

配置完之后启动服务即可

如果想要刷新配置，直接修改config-server-dev.yml文件然后调用配置中心接口/actuator/bus-refresh即可刷新所有服务的本地配置（所有服务在启动的时候会优先从远处获取配置然后保存到本地，后续都用本地的配置，所以需要rabbitmq通知每个服务刷新本地配置），调用方式如下（我采用的是idea自带的restful远程调用根据类似于postman）：

当刷新配置的时候其它服务会打印出如下日志，表明服务总线配置ok的

6、rabbitmq安装，参考以上文档即可

springcloud服务注册服务总线配置服务调用简单使用

製作docker pt-online-schema-change修改表結構工具鏡像

mysql數據庫全量備份和增量備份（docker容器部署方式）

docker部署kafka監控服務kafka-exporter

普通安裝和docker安裝process-exporter對linux進程進行監控

springcloud服務註冊服務總線配置服務調用簡單使用
