OrientDB没有返回读取顶点的输出边缘

Question

我正在尝试读取之前添加到数据库中的边缘：

declare @mytble table
(
orders int,
product varchar (50),
quantity int

)

INSERT @mytble

SELECT 100,'CUP','1' UNION ALL
SELECT 100, 'PLATE',2 UNION ALL
SELECT 101,'CUP','1' UNION ALL
SELECT 102,'CUP','2' UNION ALL
SELECT 103, 'CUP',1 UNION ALL
SELECT 103,'PLATE','3' UNION ALL
SELECT 103,'GLASS','1' 

SELECT * FROM @mytble

我正在创建以下方式：

Iterable<Vertex> startNodes = getVertexList(relationshipStorage.getStartNode(), graph);
            Iterable<Vertex> endNodes = getVertexList(relationshipStorage.getEndNode(), graph);

            List<Edge> list = StreamSupport.stream(startNodes.spliterator(), false)
                    .flatMap(vertex1 -> StreamSupport.stream(vertex1.getEdges(Direction.OUT, relationshipId).spliterator(), false))
                    .filter(edge -> StreamSupport.stream(endNodes.spliterator(), false).anyMatch(vertex -> edge.getVertex(Direction.IN).equals(vertex)))
                    .collect(Collectors.toList());

但似乎返回始终为空，因为第一个Iterable<Vertex> startNodes = this.getVertexList(storage.getStartNode(), graph); Iterable<Vertex> endNodes = this.getVertexList(storage.getEndNode(), graph); for (Vertex startNode : startNodes) { for (Vertex endNode : endNodes) { String edgeClass = "class:" + storage.getId(); Edge edge = startNode.addEdge(edgeClass, endNode); for (Map.Entry<String, Object> entry : storage.getProperties().entrySet()) { edge.setProperty(entry.getKey(), entry.getValue()); } edge.setProperty(Constants.TAG_HASH, HashCreator.sha1FromRelationship(storage)); edge.setProperty(Constants.TAG_SNAPSHOT_ID, snapshotId); } } graph.commit(); 的返回为空。 奇怪的是，如果我使用vertex1.getEdges(Direction.OUT, relationshipId)，它不会为空，但这对我没有帮助。
