How we can set the spring bean scope. And what supported scopes does it have?

There are four ways to set the scope of a Spring bean: singleton, prototype, request, and session.

The singleton scope creates a single instance of a bean, which is shared by all objects that request it.

The prototype scope creates a new instance of a bean for each object that requests it.

The request and session scopes are only available in a web-based context. The request scope creates a new bean instance for each HTTP request, and the session scope creates a single instance of a bean shared by all objects in a single HTTP session.
