How to define Bean Scope
The scope of the objects created from a particular bean definition can be defined. This gives the flexibility to choose the scope of the objects you create.
Spring Framework supports five scopes:
- Singleton: Only 1 instance of Bean will be there.
- Prototype: When Bean is called a new Instance will be created.
- Request: Single bean definition to the lifecycle of a single HTTP request; means every HTTP request will have its own instance of a bean created off the back of a single bean definition.
- ApplicationContext: Session Scopes a single bean definition to the lifecycle of a HTTP Session.
- Global session: Scopes a single bean definition to the lifecycle of a Global HTTP Session. Typically only valid when used in a port let context. Only valid for the context of web-aware Spring.
