Annotation Type DefaultImplementation
-
@Documented @Retention(RUNTIME) @Target(TYPE) @Inherited public @interface DefaultImplementation
An annotation to apply to an interface to indicate which implementation is the default implementation. The initial use case is to redirect
Replaces
to another class to allow the replacement of an implementation that isn't accessible due to visibility restrictions.For example:
@DefaultImplementation(MyImpl.class) public interface SomeInterface { } class MyImpl implements SomeInterface { } @Replaces(SomeInterface.class) class OtherImpl implements SomeInterface { }
In the above example the
OtherImpl
bean will replace theMyImpl
bean because the class in theReplaces
annotation has a default implementation.- Since:
