Spring CLI [v2.2.3.RELEASE] with MongoRepository : org.springframework.beans.factory.UnsatisfiedDependencyException

Question

I am attempting to write a simple MongoDB app with the spring cli. I used this spring with mongodb tutorial as a base, and I am getting an an UnsatisfiedDependencyException error.

Here's my code

file: Grabs.groovy

@Grab('spring-boot-starter-data-mongodb')

class Grabs {}

file: CustomerOrder.groovy

import org.springframework.data.annotation.Id

class CustomerOrder {
    @Id
    String id
    Date orderDate
}

file: MongoOrderRepository.groovy

import org.springframework.data.mongodb.repository.MongoRepository

interface MongoOrderRepository extends MongoRepository<CustomerOrder, String> {
    CustomerOrder findById(String customerId)
}

file: OrderController.groovy

@RestController
class OrderController {

    @Autowired
    MongoOrderRepository orderRepository

    @GetMapping("/{order}")
    def listOrders(@PathVariable("order") String order) {
        List<CustomerOrder> orders = orderRepository.findById(order)
        return orders
    }
}

when I do a spring run *, here are the errors

***************************
APPLICATION FAILED TO START
***************************

Description:

Field orderRepository in OrderController required a bean of type 'MongoOrderRepository' that could not be found.

The injection point has the following annotations:
    - @org.springframework.beans.factory.annotation.Autowired(required=true)


Action:

Consider defining a bean of type 'MongoOrderRepository' in your configuration.

I attempted to put in a @Repository in my MongoOrderRepository, since that worked for a Jdbc based implementation, but that did not work. I'm not sure how to proceed. Any help would be appreciated.

Thanks

Running example: https://github.com/thiagochagas/groovy-mongodb

1) Adjusts in your code:

Grabs:

@Grab(group='org.springframework.boot', module='spring-boot-starter-data-mongodb', version='2.2.3.RELEASE')

MongoOrderRepository (Optional adjust):

interface MongoOrderRepository extends MongoRepository<CustomerOrder, String> {
    Optional<CustomerOrder> findById(String customerId)
}

OrderController (List to Optional):

@GetMapping("/{order}")
def listOrders(@PathVariable("order") String order) {
    Optional<CustomerOrder> orders = orderRepository.findById(order)
    return orders
}

2) Install and Running code:

./gradlew clean build
./gradlew bootRun
