springCloudConfigDemo

   Spring Cloud Config为分布式系统中的外部配置提供服务器和客户端支持。使用Config Server,您可以在所有环境中管理应用程序的外部属性。客户端和服务器上的概念映射与Spring Environment和PropertySource抽象相同,因此它们与Spring应用程序非常契合,但可以与任何以任何语言运行的应用程序一起使用。随着应用程序通过从开发人员到测试和生产的部署流程,您可以管理这些环境之间的配置,并确定应用程序具有迁移时需要运行的一切。服务器存储后端的默认实现使用git,因此它轻松支持标签版本的配置环境,以及可以访问用于管理内容的各种工具。可以轻松添加替代实现,并使用Spring配置将其插入。

项目介绍

Spring Cloud Config 服务demo

config-server 配置服务端,服务管理配置信息;
config-client 客户端,客户端调用server端暴露接口获取配置信息

相关知识点梳理

pom.xml

+ spring-boot-starter-parent //Spring Boot的父级依赖

+ spring-cloud-dependencies  //版本依赖

+ spring-cloud-starter-config

+ spring-cloud-config-server

特征

Spring Cloud Config Server功能:
用于外部配置的HTTP,基于资源的API(名称-值对或等效的YAML内容)
加密和解密属性值(对称或非对称)
使用可轻松嵌入Spring Boot应用程序 @EnableConfigServer

Config Client功能(适用于Spring应用程序):    
绑定到Config Server并Environment使用远程属性源初始化Spring
加密和解密属性值(对称或非对称)
spring.cloud.config.uri在bootstrap.[yml | properties]中配置、通过系统属性或环境变量中设置。

获取git上的资源信息遵循如下规则

>>  /{application}/{profile}[/{label}]
>>  /{application}-{profile}.yml
>>  /{label}/{application}-{profile}.yml
>>  /{application}-{profile}.properties
>>  /{label}/{application}-{profile}.properties

application:表示应用名称,在client中通过spring.cloud.config.name配置,缺省时默认sprin.application.name的值
profile:表示获取指定环境下配置,例如开发环境、测试环境、生产环境 默认值default,实际开发中可以是 dev、test、demo、production等
label: git标签,默认值master

服务端说明

server:
  port: 3200
spring:
  application:
    name: fw-server-config
  cloud:
    config:
      server:
        git:
          uri: https://gitee.com/fw_spring/config_repo     # 配置git仓库的地址
#          search-paths: config_repo             # git仓库地址下的相对地址,可以配置多个,用,分割。
          username: ***          # git仓库的账号
          password: ***          # git仓库的密码
      label: master

客户端说明

spring:
    application:
        name: config-client
    cloud:
        config:
          #name: fw-service-provider  #应用名称,默认与spring.application.name相同
          #profile: default     #环境名称,默认default
          #label: master    #分支名称,默认master
          #uri: http://localhost:3200   #spring cloud config服务地址
          discovery:
            #表示使用服务发现组件中的Config Server
            enabled: true
            #指定Config Server在服务发现中的serviceId
            service-id: fw-server-config

   注意这里是bootstrap.yml而不是appliction.yml,因为bootstrap.yml会在应用启动之前读取, 而spring.cloud.config.uri会影响应用启动.

自动刷新数据(配合Spring Cloud Bus使用, 待验证)

  • 客户端引入 spring-boot-starter-actuator(Spring Boot Actuator,感应服务端变化)
  • 加入@RefreshScope 可以动态刷新这个Bean
  • 调用/refresh接口,注意这里要用post方法进行访问, 触发刷新

将配置中心注册到服务发现

  • 添加@EnableEurekaClient 注解
  • 在pom.xml中引用spring-cloud-starter-eureka
  • application.yml中添加 如下内容
#注册中心
eureka:
  client:
    serviceUrl:
      defaultZone: http://localhost:3100/eureka/
  instance:
    prefer-ip-address: true

通过服务发现连接配置中心(客户端)

  • 添加@EnableEurekaClient 注解
  • 在pom.xml中引用spring-cloud-starter-eureka
  • bootstrap.yml中添加 如下内容
spring:
  application:
    name: fw-config
  cloud:
    config:
      #name: fw-config-dev
      #profile: default
      #label: master
      #uri: http://localhost:3200
      discovery:
        #表示使用服务发现组件中的Config Server
        enabled: true
        #指定Config Server在服务发现中的serviceId
        service-id: spring-cloud-config-server

#注册中心
