Annotation Interface Implementation

@Target(TYPE) @Retention(RUNTIME) @Scope public @interface Implementation

Indicates that the annotated class is a custom implementation that should replace the default implementation.

A class annotated with Implementation will be automatically searched for with help of the ClassFinders and instantiated by guice. Following types are candidates for automatic registration.

Example

@Implementation(priority = Priority.NORMAL)
public class CustomMiddleware implements Middleware {
    private static final Logger log = LoggerFactory.getLogger(FirstMiddleware.class);

    @Override
    public void accept(InvocationContext<?> context) {
        log.info("run custom middleware");
    }
}
