Spring-data-neo4j map cannot be cast to nodeentity - neo4j

Question

I am using Spring-data-neo4j but meet the following problem.
Everything works fine until I want to cast the queried LinkedHashMap to an #NodeEntity. Here's the code
Movie.class
#NodeEntity
public class Movie {
#GraphId Long id;
#Property(name="title")
private String mtitle;
#Property(name="released")
private String mreleased;
#Property(name="tagline")
private String mtagline;
#Relationship(type = "REVIEWED", direction = Relationship.INCOMING)
private Set<Movie> reviewed;
#Relationship(type = "ACTED_IN", direction = Relationship.INCOMING)
private Set<Movie> actedIn;
#Relationship(type = "DIRECTED", direction = Relationship.INCOMING)
private Set<Movie> directed;
}
They repository
#Repository
public interface MovieRepository extends GraphRepository<Movie>{
#Query("MATCH (n) WHERE id(n)={0} RETURN n")
Movie getMovieFromId(Integer idOfMovie);
}
When using getMovieFromId() in the service, I get the exception:
java.lang.ClassCastException: java.util.LinkedHashMap cannot be cast to com.hersbitcloud.cancercloud.domain.Movie
com.sun.proxy.$Proxy55.getMovieFromId(Unknown Source)

The movie node in the neo4j contains property 'title', 'released', 'tagline', and relationship 'ACTED_IN', 'DIRECTED' and 'REVIEWED'.
BTW, if I change the repository type from Movie to HashMap, the exception gone.
Any help will be appreciated.

Please check if the Movie package is included in the ones supplied to SessionFactory. The OGM will map to the entity if it knows that it's a domain entity (i.e. scanned when the SessionFactory is instantiated), otherwise, it'll just send back the Map of data.
