使用play框架管理外部api调用的缓存解决方案

https://www.playframework.com/documentation/2.6.x/ScalaCache

其要点是:

• 使用实例缓存内容:

import play.api.cache._
import play.api.mvc._
import javax.inject.Inject

class Application @Inject() (cache: AsyncCacheApi, cc:ControllerComponents) extends AbstractController(cc) {

[...]
val result: Future[Done] = cache.set("item.key", connectedUser, 24.hours)
val futureMaybeUser: Future[Option[User]] = cache.get[User]("item.key")
}
