What scopes of beans do you know in Spring?

In Spring, the following main bean scopes exist:

• singleton (default) — one instance of the bean for the entire Spring context.
• prototype — a new bean instance is created each time it is requested.
• request — the bean lives within the scope of an HTTP request (for web applications).
• session — the bean lives within the scope of an HTTP session.
• application — the bean lives within the scope of the ServletContext.
• websocket — the bean lives within the scope of a WebSocket session.

Each scope defines the lifetime and visibility of the bean, allowing flexible management of state and resources in the application.
