consul config spring cloud 2022

原理就是把项目中application.yml中的配置移到consul中进行远程管理

当项目启动的时候，去远程读取配置文件的内容，并加载。

项目中resource下面的application.yml删除

新建bootstrap.yml文件

spring:
  application:
    name: consulpayment
  cloud:
    consul:
      host: machine136
      port: 8500
      discovery:
        service-name: consulpayment
      config:
        format: yaml
        default-context: application #默认全局配置
        profile-separator: "-" #配置文件名称和环境的连接符，这里修改为- ,例如 ${spring.application.name}-${spring.profiles.active}
        data-key: data #这是config的数据key
        prefixes: config
        enabled: true
        import: optional:consul:machine136:8500

  profiles:
    active: dev

prefixes:对应consul配置的config目录名称

format:指定了consul 配置数据的格式（输入data时右上角的选择）

default-context:application 代表项目的默认配置位于 {prefixes}/{default-context}/{data-key}

profile-separator:"-" 与

proeiles:

　　active:dev

共同定义了环境配置文件的路径为 {prefixes}/{spring.application.name}{profile-separator}{spring.profiles.active}/{data-key}

就是：config/consulpayment-dev/data

根目录新增

注意value 中不能用 tab 只能用空格！！！

否则报错

found character '\t(TAB)' that cannot start any token. (Do not use \t(TAB) for indentation)
in 'reader', line 2, column 1:
port: 8032

环境个性化配置

创建完成后的效果：

IEDA 项目测试注意增加两个starter : consul-config和bootstrap
