Ich bin dabei, meine Anwendung zu migrieren, um SDN 4.1.0.RC1 zu verwenden, habe aber nach dem Startversuch der Anwendung einige Probleme festgestellt. Ich habe die notwendigen Konfigurationsänderungen vorgenommen, um den HTTPDriver korrekt zu meinem Remote-Server zu verwenden (localhost: 7474) und beim Booten der Anwendung erhalte ich den folgenden Fehler mit einem meiner Repositories, während ich versuche, den Spring-Kontext zu laden.GraphQueryLookupStrategy.resolveQuery-Ausnahme bei der Migration von SDN 4.0 zu SDN 4.1.RC1

Dies ist das vanilia Repository, das
@Repository
public interface UserRepository extends GraphRepository<User> {
@Query("MATCH (u:User) where u.authId = {authId} return u limit 1")
User findOneByAuthId(@Param("authId") Long authId);
}
EDIT
Es weinen zu sein scheint sieht aus wie es eine Trennung zwischen der Version von Federdaten und Federdaten Neo4j sein könnte.
Die GraphQueryLookupStrategy in Frage ...

Es erscheint das QueryLookupStrategy Ich habe ein Verfahren RepositoryQuery resolveQuery(Method method, RepositoryMetadata metadata, NamedQueries namedQueries);
erwartet umgesetzt werden, die eindeutig ist es nicht. Ich nehme an, dies ist nun ein Abhängigkeitsproblem und wird untersuchen, weiter mit der Version von Spring Data I mit SDN

funktioniert perfekt! Danke @Holycowzer! – Lina
Das hat funktioniert. Inzwischen können Sie Hopper-RELEASE verwenden und das funktioniert immer noch. –
