2、配置文件

Spring Boot 配置文件的加载顺序，依次为 bootstrap.properties -> bootstrap.yml -> application.properties -> application.yml ，其中 bootstrap.properties 配置为最高优先级，配置如下：

nacos-config：

group：config的分组
file-extension：动态配置文件类型

注意：
若是引用了config的pom，这里必须使用 bootstrap.properties 进行配置，否则启动回报连接超时
注意：你可以使用 spring.cloud.nacos.config.refresh.enabled=false 来关闭动态刷新
可通过spring.profiles.active切换部署环境配置
其Data ID它的定义规则是：${prefix}-${spring.profile.active}.${file-extension}

在这里插入图片描述

2.1添加本地配置

bootstrap.properties修改spring.cloud.nacos.config.prefix=application-provider-1
application.yml 修改server.port:8008和dubbo.protocol.port:8998
application-provider-1.yml添加如下配置

localConfig: abc

bootstrap.properties修改spring.cloud.nacos.config.prefix=application-provider-2
application.yml 修改server.port:8009和dubbo.protocol.port:8999
application-provider-2.yml添加如下配置
