I have the following GraphRepository class for Feed.
public interface FeedRepository extends GraphRepository<Feed>,
RelationshipOperationsRepository<Feed>{
Feed findById(Long id);
List<Feed> findByFeedType(String feedtype);
@Query("match (user:User {username:{0}}), (f:Feed) where f.feedType in {1} "
+ "with user,f "
+ "order by f.timeAdded desc "
+ "optional match (user)-[r:LIKED]->(f) "
+ "return f, count(r)")
Iterable<Map<String, Object>> getAllFeeds(String username, String[]
typeFilter, Pageable pageable);
}
Getting the following error while compiling the code. I am using Spring
Data neo4j version 3.
Caused by: java.lang.IllegalStateException: Method has to have one of the
following return types! [interface org.springframework.data.domain.Slice,
interface org.springframework.data.domain.Page, interface java.util.List]
