What scopes do Spring beans have?

In Spring, the following main scopes for beans exist:

• singleton (default) — one instance of the bean for the entire Spring container.
• prototype — each request to the container creates a new instance of the bean.
• request — the bean lives within a single HTTP request (applicable in web applications).
• session — the bean lives within the user's HTTP session.
• application — the bean lives within the ServletContext, i.e., at the level of the entire web application.
• websocket — the bean lives within a WebSocket session.

Example of a declaration with scope prototype:

@Component
@Scope("prototype")
public class MyBean {
    // ...
}
