Scala 使用Spring创建存储库bean时出错

我设置了Neo4j内核1.9M04和Spring-Data-Neo4j 2.1.0版本

更准确地说，这里是我的依赖项（来自我的SBT文件）：

在运行时，尝试自动连接neo4j存储库时，我得到了以下堆栈：

我注意到类

org/neo4j/kernel/impl/core/LockReleaser

已从neo4j 1.9M0X中消失

该错误似乎来自

“org.springframework.data”%”spring-data-neo4j-rest“%”2.1.0.RELEASE“

---

我怎样才能解决这个问题

看起来spring orm是针对运行时尝试使用的不同版本的neo4j构建的（它们不兼容）

可能的解决办法：

• 使用旧版本的neo4j
• 根据当前版本的neo4j自行构建spring orm。可能您必须自己迁移spring orm

---

我不能使用旧版本的Neo4j，因为scala 2.10与旧版本1.9M04的Neo4j不兼容。Spring-Data-Neo4j 3.2.0.RELEASE似乎不完全支持Neo4j 1.9.X版本。保持Scala 2.10作为主语言的最佳解决方案是不使用Spring数据，而是回到传统的Neo4j API。
