Neo4j 从SDN 4.0迁移到SDN 4.1.RC1时发生GraphQueryLookupStrategy.resolveQuery异常

我正在将我的应用程序迁移到使用SDN 4.1.0.RC1的过程中，但在尝试启动应用程序后遇到了一些问题。我已经进行了必要的配置更改，以便在远程服务器（localhost:7474）上正确使用HTTPDriver，并且在启动应用程序时，在尝试加载spring上下文时，我的一个存储库出现以下错误

看来我的QueryLookupStrategy需要一个方法

RepositoryQuery resolveQuery（方法方法，RepositoryMetadata，NamedQueries NamedQueries）要实现，但显然不是。我假设这现在是一个依赖性问题，并将进一步研究Spring数据的版本，以符合SDN

好吧，如果你遇到这个问题，有一个非常直接的方法来解决它。请参阅上的文档。此异常是由与spring数据共享模块的版本冲突引起的。neo4j在版本4.1.0.RC1中实现的接口已更改，因此引发此异常

要解决此问题，请使用弹簧数据释放序列BOM，并将其设置为释放Hopper-RC1。由于我使用gradle，说明如下，但您也可以在上面的链接中找到它们

相关构建脚本简化

buildscript {
  dependencies {
    classpath "io.spring.gradle:dependency-management-plugin:0.4.0.RELEASE"
  }
}

apply plugin: "io.spring.dependency-management"

dependencyManagement {
  imports {
    mavenBom 'org.springframework.data:spring-data-releasetrain:Hopper-RC1'
  }
}

dependencies {
    compile 'org.springframework.data:spring-data-neo4j:4.1.0.RC1'
}repositories {
    maven {
        url 'https://repo.spring.io/libs-milestone'
    }
}

干杯

为Maven用户详细介绍了@Holycowzer的答案。将以下行添加到builds POM.xml中。请注意，这将位于主
标记集之外

<dependencyManagement>
  <dependencies>
    <dependency>
        <groupId>org.springframework.data</groupId>
        <artifactId>spring-data-releasetrain</artifactId>

org.springframework.data
弹簧数据释放装置
料斗-SR1
聚甲醛
进口

我注意到一些导入在执行此操作时中断，只需在POM中显式地将它们作为依赖项添加，所有内容都应按预期工作。
这很有效。到现在为止，您可以使用料斗释放，这仍然有效。
