如何一次查询多个条目

Question

I am using spring boot reactive and Couchbase

Flux<Item> findByLocation_LocationIdOrderByCreatedAtDesc(String locationId);

Just to point here I am accessing Location.locationId. Location object has locationId field in main document

Also below properties is not printing the generated Couchbase query, if anyone can help with that too,

logging: level: org.springframework.data: DEBUG

The response is fine when database has only one entry, but when the db has more than one entry matching criteria it throws "Source emitted more than one item".

My controller is returning

Flux<Item>

Answer 1

Following two annotations are mandatory or it keep returning the exception

@N1qlPrimaryIndexed @ViewIndexed

@Ghrissology I already had ReactiveCouchbaseRepository

Answer 2

Normally, the spring Data change the query based on the return type. if you want one result it use getSingleResult() automatically:

Item findByLocation_LocationIdOrderByCreatedAtDesc(String locationId);

in you case, i think he didn't understand the return type because you didn't implement a ReactiveCrudRepository:

public interface ReactiveItemRepository
  extends ReactiveCrudRepository<item, String> {}
