Steps to Reproduce

0. Introspected annotation on the DirectionDTO bean resides in its own module (maps-common) which is shared by service and gateway modules.

The repository definition in the service module looks like this:

public interface DirectionRepository extends CrudRepository<Direction, Long> {

    List<DirectionDTO> findByStartAndEndAndProviderOrderByPositionAsc(Place start, Place end, MapProvider provider);

    // this works, not the DTO variant above
    //List<Direction> findByStartAndEndAndProviderOrderByPositionAsc(Place start, Place end, MapProvider provider);
}

It should not be required to annotate Direction JPA entity with @Introspected.

1. Steps to reproduce: git clone https://github.com/aruld/maps-app.git git checkout micronaut-data-support

Run consul:

docker run -p 8500:8500 consul:1.4.4

Run the service from maps-service dir: ./gradlew run

Run the gateway from maps-gateway dir: ./gradlew run

Invoke the API using curl: curl "http://localhost:8080/api/maps/fastest?src=apple&dest=google"

Expected Behaviour

{"directions":[{"position":0,"text":"Turn right onto N Shoreline Blvd","distanceInMiles":0.3,"timeInMinutes":1},{"position":1,"text":"Take a slight right turn to merge onto CA-85 South","distanceInMiles":0.6,"timeInMinutes":1},{"position":2,"text":"Keep left to merge onto CA-85 South","distanceInMiles":0.2,"timeInMinutes":1},{"position":3,"text":"Take the exit to merge onto I-280 toward San Jose","distanceInMiles":5.4,"timeInMinutes":6},{"position":4,"text":"Take exit 11 onto De Anza Boulevard","distanceInMiles":1.5,"timeInMinutes":1},{"position":5,"text":"Turn right onto N De Anza Blvd toward Cupertino, Saratoga","distanceInMiles":0.2,"timeInMinutes":1},{"position":6,"text":"Turn left onto Mariani Ave","distanceInMiles":0.3,"timeInMinutes":1}],"timeInMinutes":12}

Actual Behaviour

It fails with an introspection error on the client side:

{"message":"Internal Server Error: Internal Server Error: Internal Server Error: Error instantiating type [maps.common.DirectionDTO] from introspection: No bean introspection available for type [class maps.common.DirectionDTO]. Ensure the class is annotated with io.micronaut.core.annotation.Introspected"}

• JDK Version: 1.8

Example Application

• link to github repository with example that reproduces the issue https://github.com/aruld/maps-app (branch micronaut-data-support)

[jameskleeh]

Your dependencies in common are incorrect:

compile "io.micronaut:micronaut-core:1.2.5"

should be

    compile "io.micronaut:micronaut-inject:1.2.5"
    annotationProcessor "io.micronaut:micronaut-inject-java:1.2.5"

Thank you @jameskleeh for helping with this.
