配置中心

前言

本文介绍如何建立配置中心，服务器；

操作步骤

• 使用idea新建立工程com.nick.client,依赖配置加入

• cloud discovery -> eureka discovery

• web -> web

• cloud config -> config server

• ClientApplication类添加注解@EnableDiscoveryClient与@EnableConfigServer

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

• 在码云、gitlab、或者github上建立配置项目config-repo，记录该项目的地址；

• 项目内新建order/order.yml

spring:
  application:
    name: order  # 这里数据库一般在生产环境上不同服务
  datasource:
    driver-class-name: com.mysql.jdbc.Driver
    username: root
    password: 123456
    url: jdbc:mysql://127.0.0.1/diancan?characterEncoding=utf-8&useSSL=false
  jpa:
    show-sql: trueeureka:
  client:
    service-url:
      defaultZone: http://localhost:8761/eureka/#-Dserver.port=8081#server:#  port: 8081

• 修改application.properties为application.yml

spring:
  application:
    name: config
  cloud:
    config:
      server:
        git:
          uri: https://github.com/qiujiahong/config-repo
          username:
          password:
          search-paths: order          default-label: master
eureka:
  client:
    service-url:
      defaultZone: http://localhost:8761/eureka/

• 启动项目，访问尝试http://localhost:8080/order/order.yml ,http请求地址和资源文件映射如下:

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