JavaCache

The Play cache API

The default implementation of the Cache api uses EHCache. You can also provide your own implementation via a plugin.

Accessing the Cache API

The cache api is provided by the play.cache.Cache object. It requires to have at least a cache plugin registered.

Note: The API is voluntary minimal to allow several implementations to be plugged. If you need a more specific API, use the one provided by your Cache plugin.

Using this simple API you can either store data in cache:

Cache.set("item.key", connectedUser)

And then retrive it later:

User maybeUser = Cache.get("item.key")

Caching HTTP responses

You can easily create a smart cached action using standard Action composition.

Note: Play HTTP Result are safe to cache and reuse later.

Play provides a default built-in helper for standard cases:

@Cached("homePage")
public static Result index() {
  return ok("Hello world");
}
