Neo4j とブループリントの問題を解決しようとしています。頂点の追加は、それらにプロパティを追加するだけでなく、正常に機能します。しかし、データベースから頂点を読み取ろうとすると問題が発生します。それらはすべて読み取られているため、それらの数は問題ありませんが、プロパティとエッジがランダムにありません。それらの代わりに、ヌルを取得しています。非常に奇妙なことは、Vertex が一度 null プロパティを持つ場合、別の時には期待値を持つことです。私も PlayFramework を使用しており、更新のたびに、プロパティ (名前: Jan、名前; Adam) を持つ 2 つの頂点を追加しています。グラフ埋め込みデータベースからのデータの読み取りに問題があるようです。誰かが同様のトラブルを経験しましたか？私の問題をよりよく理解できるように、デバッグ付きのリストを添付します。すべての応答に事前に感謝します;）
