neo4j - @Query result type different between ImpermanentGraphDatabase and SpringCypherRestGraphDatabase? -

-

i using @query annotation on repository interface method retrieve list of nodes contained in path.

if switch impermanentgraphdatabase springcypherrestgraphdatabase, having errors while parsing results because type returned query different :

context :

  • using sdn 3.3.0.release , neo4j 2.1.7
  • code used in junit test
  • my graph : (t:type1)-[:has_key]->(:key)-[:next]->(:key)-[:next]->(:key)-[:next]->.... , on (yeah, sounds linkedlist ^^)

  • the query "i want keys associated type" used path query :

    match (key:key)<-[:has_key]-(:type1 {typeid :{0}}), p=(key)-[:next*]->(:key) return nodes(p) order length(p) desc limit 1

using impermanentgraphdatabase :

  • my query returns iterable<iterable<object>> , have cast "object" inside nodeentity using neo4joperations.convert(...) method because objects of type nodeproxy.

using springcypherrestgraphdatabase :

  • my query returns iterable<iterable<map<string, string>>>, , map contains property name of node key , corresponding value map entry value.

why there such implementation difference ? shouldn't expect same behaviour regardless of database service implementation ?

thank you.

p.s. : way, tried achieve same goal using traversaldescription: works , same traversaldescription works on both database implementations
