Class RequestScope

  • public class RequestScope
extends java.lang.Object
    Provides something similar to a request scope in Spring or Guice. Objects are stored within Play's Http.Context which is created anew for each request. It's a very useful storage that lasts just for the current request. You can e.g. store a StudyRequest that you retrieved from the database and reuse it later on without having to retrieve it from the database again. This saves resources and brings performance.
