使用Spring创建存储库bean时出错

Question

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

更确切地说，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：

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

似乎错误提供了"org.springframework.data" % "spring-data-neo4j-rest" % "2.1.0.RELEASE"

我怎么能解决这个问题？

Answer 1

看起来spring-orm是针对不同版本的neo4j构建的，而不是你在运行时尝试使用它们（它们是不兼容的）。

可能的解决方案：

• 使用旧版本的neo4j。
• 针对当前版本的neo4j自行构建spring-orm。 可能你必须自己移动spring-orm。
