詳細
Description

By default services are "singleton" scoped which means that clients of a service only ever use a single instance (a singleton) of the service. This behaviour can be changed by specifying a scope attribute with on the following values:

  • prototype - A new service is created every time it is injected into another class
  • request - A new service will be created per request
  • flash - A new service will be created for the current and next request only
  • flow - In web flows the service will exist for the scope of the flow
  • conversation - In web flows the service will exist for the scope of the conversation. ie a root flow and its sub flows
  • session - A service is created for the scope of a user session
  • singleton (default) - Only one instance of the service ever exists

See Scoped Services in the user guide for more information.
