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
