Annotation Interface Fallback

@Target({TYPE,METHOD})
@Retention(RUNTIME)
@Documented
public @interface Fallback

Indicates that a bean qualifies as a fallback autowire candidate. This is a companion and alternative to the Primary annotation.

If all beans but one among multiple matching candidates are marked as a fallback, the remaining bean will be selected.

Just like primary beans, fallback beans only have an effect when finding multiple candidates for single injection points. All type-matching beans are included when autowiring arrays, collections, maps, or ObjectProvider streams.
