Question

我有以下关系

图-有很多连接连接-有很多MoveablePoints

我正在使用neo4j的neo4j omg存储库接口v3.1.3来持久添加和删除连接和可移动点。我的单元测试工作正常，但是，如果在Web环境中使用它，则不会删除连接。

我正在使用5的可变深度持久性。我觉得这与omg会话有关，但我不确定。任何想法都将受到欢迎。

服务代码

@Transactional
    @Override
    @Retryable(value = TransientException.class,exceptionExpression="#{message.contains('RWLock')}", maxAttempts = 5)
    public Diagram update(Diagram diagram) throws GUMLException {

//        for (Connection connection : diagram.getConnections())
//            if (connection.getId() != null)
//                connectionService.deleteMoveablePoints(connection.getId());
//
//        for (DiagramElement de : diagram.getDiagramElements()) {
//            diagramElementService.save(de);
//        }


        return umlDiagramRepository.save(diagram, 5);

    }

域类

@NodeEntity
public class Diagram {
   public Set<Connection> getConnections() {
        if (connections == null)
            connections = new HashSet<Connection>();
        return connections;
    }

    public void setConnections(Set<Connection> connections) {
        this.connections = connections;
    }

    @org.neo4j.ogm.annotation.Relationship(type = "HasConnections", direction = org.neo4j.ogm.annotation.Relationship.OUTGOING)
    Set<Connection> connections;

}

@NodeEntity
public class Connection implements IConnector {
  public Set<MoveablePoint> getMoveablePoints() {
        return moveablePoints;
    }

    public void setMoveablePoints(Set<MoveablePoint> moveablePoints) {
        this.moveablePoints = moveablePoints;
    }


    @org.neo4j.ogm.annotation.Relationship(type = "HasMoveablePoints", direction = org.neo4j.ogm.annotation.Relationship.OUTGOING)
    private Set<MoveablePoint> moveablePoints;

}

当我更改服务代码以首先从会话中检索对象然后覆盖时，它似乎起作用了。不过，这对我来说似乎不正确。

Diagram d2 = umlDiagramRepository.findById(diagram.getId()).get();
        d2 = diagram;

        return umlDiagramRepository.save(d2, 5);

变量深度持久性和Set类型的关系
