Spring Framework support total seven scopes, out of which five are available only if you use a web-aware ApplicationContext.
- singleton
-
This is the default scope for any bean. It created a single object instance for a single bean definition per Spring IoC container.
- prototype
-
Any number of object instances can be created for a single bean definition. Everytime we request a bean using
getBean()method call on the IoC container, a new instance will be returned.
web-aware Beans Scopes are:
- request
-
Each HTTP request will create its own instance of bean from a single bean definition.
- session
-
Scopes a single bean definition to the lifecycle of an HTTP session.
- globalSession
-
Scopes a single bean definition to the lifecycle of an global HTTP session. Only valid for Portlet context.
- application
-
Scopes a single bean definition to the lifecycle of a
ServletContext. - websocket
-
Scopes a single bean definition to the lifecycle of a
WebSocket.
