Java中EnvironmentAware 接口的作用

nacos.config.server-addr=IP地址
nacos.config.data-id=api.properties

nacos.config.namespace=public

nacos.config.password=nacos
nacos.config.auto-refresh=true
nacos.config.type=properties
nacos.config.bootstrap.enable=true
nacos.config.bootstrap.log-enable=true

   其实说白了就是哪个接口需要获取配置，那么那个接口就需要进行实现该接口并实现里面的set方法
