Endless execution when calling `save(object, depth)` method on Neoj4Session instance

Syfer · November 19, 2020, 11:28am

Hi everyone,

After database migration from neo4j 3.5. * to 4.1.* server and Spring Neo4j Data dependencies update to version 5.3.4.RELEASE, the save (object, depth) method stopped working. It looks like it hangs at this place:

neo4jSession.save(actualRelation, 0); // actualRelation is an instance of ProfileParentGroupRelation class

ProfileParentGroupRelation.java:

@RelationshipEntity(type = "HAS_PARENT")
public class ProfileParentGroupRelation extends TimespanRelationship {

	@StartNode
	private Profile profile;

	@EndNode
	private Group parent;
	private List<Integer> userRoles;
	
	public ProfileParentGroupRelation() {
	}
	public Profile getProfile() {
		return profile;
	}
	public void setProfile(Profile profile) {
		this.profile = profile;
	}
	public Group getParent() {
		return parent;
	}
	public void setParent(Group parent) {
		this.parent = parent;
	}
	public List<Integer> getUserRoles() {
		return userRoles;
	}
	public void setUserRoles(List<Integer> userRoles) {
		this.userRoles = userRoles;
	}
}

I suspect that the problem is in the call "neo4jSession.save()", because I’ve raised same problem in other places where this call is used.

Please help me to understand the reason of the following problem. Any help would be appreciated.

UPDATES:

Source:

System.out.println("Start of [neo4jSession.save(actualRelation,0)]");			
neo4jSession.save(actualRelation,0);	
System.out.println("End of [neo4jSession.save(actualRelation,0)]");

Will look into this in more detail but you could help me with some information:
From which version of Spring Data Neo4j did you upgrade?
Could you give us an excerpt of the Profile and Group classes?

Syfer · November 24, 2020, 10:31am

the previous version of Spring Data Neo4j was 5.0.1.RELEASE (with neo4j server 3.5.*) providing by this dependency manager:
