Dryad

Build Status Maven Central codecov

Dryad 是一个配置文件管理客户端,它提供了配置文件的热加载等功能。并且在不改变原有 Ref 的情况下实现数据的变更。

获取

Consul

"io.growing" %% "dryad-consul" % $VERSION

使用

application.conf

dryad {

  namespace = "default"
  group = "prod"

  provider = "io.growing.dryad.provider.ConsulConfigProvider"

  consul {
    host = "localhost"
    port = 8500
  }
}

Case Class

@Configuration(name = "env.conf", parser = classOf[DevConfigParser])
case class DevConfig(name: String, group: String)

class DevConfigParser extends ConfigParser[DevConfig] {
  override def parse(config: Config): DevConfig = Configs[DevConfig].extract(config).value
}

Sample

val configSystem = ConfigSystem()
val devConfig = configSystem.get[DevConfig]

//devConfig 可以作为一个全局的常量,因为 devConfig 是一个 Config 的 Ref, 当配置文件更新时这个 Ref 会指向新的对象(配置文件更新之后所生成的对象)。
You can’t perform that action at this time.
