我设置了 Neo4j-Kernel 1.9M04 和 Spring-Data-Neo4j 2.1.0 RELEASE。

更准确地说，这里是我的依赖项（来自我的 SBT 文件）：

    "org.springframework" % "spring-aop" % "3.2.0.RELEASE",
    "org.springframework" % "spring-aspects" % "3.2.0.RELEASE",
    "org.springframework" % "spring-beans" % "3.2.0.RELEASE",
    "org.springframework.data" % "spring-data-commons-core" % "1.4.0.RELEASE",
    "org.springframework" % "spring-expression" % "3.2.0.RELEASE",
    "org.springframework" % "spring-jdbc" % "3.2.0.RELEASE",
    "org.springframework" % "spring-orm" % "3.2.0.RELEASE",
    "org.springframework" % "spring-test" % "3.2.0.RELEASE",
    "org.springframework" % "spring-tx" % "3.2.0.RELEASE",
    "org.springframework.data" % "spring-data-neo4j" % "2.1.0.RELEASE" excludeAll(
      ExclusionRule(organization = "com.sun.jdmk"),
      ExclusionRule(organization = "com.sun.jmx"),
      ExclusionRule(organization = "javax.jms")
      ),
    "org.neo4j" % "neo4j" % "1.9.M04",
    "org.neo4j" % "neo4j-kernel" % "1.9.M04" % "test" classifier "tests" classifier "",
    "asm" % "asm-all" % "3.1",
    "org.specs2" %% "specs2" % "1.13" % "test" withSources(),
    "org.springframework.data" % "spring-data-neo4j-rest" % "2.1.0.RELEASE"

在运行时，尝试自动装配 neo4j 存储库，我有这个堆栈：

我注意到这个类org/neo4j/kernel/impl/core/LockReleaser已经从 Neo4J 1.9M0X 中消失了。

似乎该错误来自"org.springframework.data" % "spring-data-neo4j-rest" % "2.1.0.RELEASE"

我该如何解决这个问题？

看起来 spring-orm 是针对不同版本的 neo4j 构建的，而不是您在运行时尝试使用的版本（它们不兼容）。

可能的解决方案：

  • 使用旧版本的 neo4j。
  • 根据当前版本的 neo4j 自己构建 spring-orm。您可能必须自己迁移 spring-orm。
