Is there a JSR-330 equivalent of Spring's @Bean or Guice's @Provides annotation?

I tried using @Named annotation on methods that create a bean, but that doesn't seem to work. Couldn't find any question here or a blog that confirms this. Reading the description at jcp.org, I don't see any relationship b/w beans and dependency injection introduced by JSR-330 either: https://jcp.org/en/jsr/detail?id=330

No, JSR-330 does not have the equivalent of Spring's @Bean or Guice's @Provides annotations.

There are only 5 annotations in JSR-330, and they are equivalent to the following Spring1 / Guice2 annotations:

JSR-330      Spring                Guice
----------   -------------------   ------------------
@Inject      @Autowired            @Inject
@Named       @Component            @Named
@Qualifier   @Qualifier            @BindingAnnotation
@Scope       @Scope                @ScopeAnnotation
@Singleton   @Scope("singleton")   @Singleton
-            @Scope("prototype")   -

1) From Using JSR 330 Standard Annotations and Using JSR 330 Standard Annotations
2) From JSR-330 Integration

They do not match up exactly, so read the articles listed in the footnotes for full detail.
