Spring Bean scope in JSP: springbean

Scope of Spring Bean in JSP

The Bean element has a scope attribute to define the Bean scope. The attribute has the following values:

1> singleton:

In Singleton mode, in the entire spring IOC container, only one instance is generated for beans in the singleton mode scope. Generally, the default Bean scope of Spring containers is singleton.

2> prototype:

Opposite to singleton, a new Bean instance is generated every time the Bean under this scope is obtained through the getBean () method of the container.

3> request:

For the same Http request, only one instance is generated for the Bean under the request scope. This scope is valid only when Spring containers are used in Web applications.

4> session:

For the same Http session, only one instance is generated for beans in the session scope. This scope is only valid when Spring containers are used in Web applications.

5> global session:

Each global Http Session corresponds to a Bean instance.
