scala之在嵌入式数据库中使用 Scala 中的 Cypher 失败

我使用来自 Scala 2.11.1 的 neo4j-jdbc 2.0.2 和 Neo4J 数据库 2.0.3。虽然通过 rest 接口(interface)向 Neo4J 服务器发送 Cypher 查询效果很好，但在嵌入式数据库中使用 Cypher 查询会失败。在对 Neo4J 资源进行了一些研究之后，我发现原因在 Cypher API 内部，同时在 ExecutionEngine 内部调用执行。我该怎么做才能修复它？

def main(args: Array[String]) { 
  val db = new GraphDatabaseFactory().newEmbeddedDatabase("D:/Datenbanken/neo4j/testsnn") 
  val engine = new ExecutionEngine(db) 
  val result = engine.execute("MATCH (n) return n") 
  println(result) 
} 

这段代码的执行在运行时产生

请您参考如下方法:

恢复 Mikesname 和 Michael Hunger 的有用评论我可以自己回答这个问题:如果我想将 Scala 的 Neo4j 数据库的嵌入式版本与 Cypher 查询一起使用，我必须使用与 Cypher 查询相同的 Scala 版本对于 Cypher 实现(当前为 Scala 2.10)，因为它在同一个 JRE 中运行。
