不能在密码查询中使用 EXISTS

Question

我正在使用 spring-data 和 neo4j 开发一个 java 项目。我尝试使用谓词 EXISTS 编写一个密码查询，但我有一个错误告诉我 "nested exception is Unknown function 'EXISTS'"。我有以下 pom.xml :

我了解到 spring-data-neo4j 版本 3.1.5.RELEASE 嵌入了 neo4j 2.1.2，其中不存在函数 EXISTS。这就是为什么我尝试将 spring-data-neo4j 版本升级到 3.2.2（其中嵌入了包含 EXISTS 谓词的 neo4j 版本 2.1.5）但是当我这样做时我的应用程序上下文无法加载：

有谁知道为什么 class org.springframework.core.DefaultParameterNameDiscoverer 找不到？我试图在我的 pom.xml 中包含许多依赖项，但我认为我的工作方式不佳。我将不胜感激一些帮助升级 neo4j 版本以便能够在 cypher 中使用 EXISTS 谓词。

非常感谢

您有版本冲突。理想情况下，您始终使用最新版本的工具，除非您有充分的理由不这样做。

要找出最新的，请转到项目主页或使用 maven 中央存储库的搜索功能：

http://search.maven.org/

然后你继续创建你想要在特定版本中拥有的库的依赖关系图，以确定其他库的哪些版本与它很好地对应。从那里您可以构建您的库/版本图。

如果您需要知道哪个版本的哪个库包含特定的 class，请在存储库搜索中使用 fc: 开关，如下所示：

fc:org/springframework/core/DefaultParameterNameDiscoverer

拥有一个可以直观地创建依赖关系图的 IDE 也很有帮助（我使用 NetBeans，它的依赖关系图很有帮助）。

在您的特定情况下：使用 spring 版本 4.1.6 或更高版本，它应该可以工作。

如果您运行遇到无法修复的冲突，您可以下载工具的源代码及其依赖项并自行编译，在出现不一致时修复它们。但这是一条艰苦而繁重的路线，只有在正常程序失败的情况下，我才会建议这样做。
