我想访问以下配置
customers {
"cust1" {
clientId: "id1"
attrs {
att1: "str1"
att2: "str2"
att3: "str3"
att4: "str4"
}
}
"cust2" {
clientId: "id2"
attrs: {
att1: "faldfjalfj"
att2: "reqwrewrqrq"
}
}
"cust3" {
clientId: "id3"
attrs {
att2: "xvcbzxbv"
}
}
}
为Map[String, CustomerConfig]
,其中CustomerConfig
是
package models
import play.api.ConfigLoader
import com.typesafe.config.Config // I added this import in order to make the documentation snippet compile to the best of my knowledge.
case class CustomerConfig(clientId: String, attrs: Map[String, String])
object CustomerConfig {
implicit val configLoader: ConfigLoader[CustomerConfig] = new ConfigLoader[CustomerConfig] {
def load(rootConfig: Config, path: String): CustomerConfig = {
val config = rootConfig.getConfig(path)
CustomerConfig(
clientId = config.getString("clientId"),
attrs = config.get[Map[String, String]]("attrs").map { case (attr, attrVal) =>
(attr, attrVal)
})
}
}
}
作为参考,这是我当前尝试参考的方式:
val resellerEnvMap = conf.get[Map[String, CustomerConfig]]("customers").map {
case (customer, customerConfig) =>
customer -> customerConfig.attrs.map {
case (attr, attrVal) =>
attr -> new Obj(attrVal, customerConfig.clientId)
}
}
基于custom config loader documentation。
问题在于,根据我认为的API docs,config.get[A]
不存在(config.getMap[K, V]
也没有)。我想要一种从配置文件填充map
的方法。我的最终目标是在Map[String, Map[String, (String, String)]]
的功能范围内填充任何内容,其中第一个String
是客户名称,第二个是属性名称,第三个是属性值,最后,第四个是客户ID。
答案 0 :(得分:3)
播放2.6使用com.typesafe:config 1.3.2,而您发布的链接似乎来自版本2?这是一种实现方法:
object CustomerConfig {
implicit val configLoader: ConfigLoader[CustomerConfig] = new ConfigLoader[CustomerConfig] {
def load(rootConfig: Config, path: String): CustomerConfig = {
val config = rootConfig.getConfig(path)
import scala.collection.JavaConverters._
val attrConfig = config.getConfig("attrs")
CustomerConfig(
clientId = config.getString("clientId"),
attrs = attrConfig.entrySet().asScala.map { entry =>
(entry.getKey, attrConfig.getString(entry.getKey))
}.toMap
)
}
}
}
