Annotation Type Scope


@Target(value={TYPE,METHOD})
@Retention(value=RUNTIME)
@Documented
public @interface Scope

When used as a type-level annotation in conjunction with the Component annotation, indicates the name of a scope to use for instances of the annotated type.

When used as a method-level annotation in conjunction with the Bean annotation, indicates the name of a scope to use for the instance returned from the method.

In this context, scope means the lifecycle of an instance, such as singleton, prototype, and so forth. Scopes provided out of the box in Spring may be referred to using the SCOPE_* constants available in via ConfigurableBeanFactory and WebApplicationContext interfaces.

To register additional custom scopes, see CustomScopeConfigurer.
