Question

当我启动baasbox时，我在提交时收到NullPointerException。我在baasbox的DbHelper.java文件中注释掉了事务逻辑。

orientdb版本是1.6.3。之前在这个版本中出现过这个问题吗？

有人对此有所了解吗？

以下是例外：

java.lang.NullPointerException: null

该语句已被评论，因为OrientDB 1.6.3对于事务和图形数据库有一些限制（对于一些BaasBox用例）。 OrientDB 1.7.x已经消失了这些限制。结果是BaasBox 0.8.4现在完全支持必要的事务，并且DbHelper类的源代码确实已经更新。

请参阅https://github.com/baasbox/baasbox/blob/0.8.4/app/com/baasbox/db/DbHelper.java#L130

在commit - orientdb的baasbox代码中获取NullPointerException
