neo4j - 从 SDN 4.0 迁移到 SDN 4.1.RC1 时出现 GraphQueryLookupStrategy.resolveQuery 异常

Question

我正在迁移我的应用程序以使用 SDN 4.1.0.RC1，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，以便正确地将 HTTPDriver 用于我的远程服务器 (localhost:7474)，并且在启动应用程序时，我在尝试加载 spring 上下文时，我的一个存储库出现以下错误。

这就是好像要哭的vanilia仓库

@Repository
public interface UserRepository extends GraphRepository<User> {

  @Query("MATCH (u:User) where u.authId = {authId} return u limit 1")
  User findOneByAuthId(@Param("authId") Long authId);

}

编辑

看起来可能是spring data和spring data neo4j的版本脱节了。

有问题的 GraphQueryLookupStrategy...

看来我拥有的 QueryLookupStrategy 期待一个方法 RepositoryQuery resolveQuery(Method method, RepositoryMetadata metadata, NamedQueries namedQueries); 被实现，但显然不是。我认为这现在是一个依赖性问题，并将进一步调查我需要与 SDN 兼容的 Spring Data 版本

Answer 1

好的，所以如果您遇到这个问题，有一种非常直接的方法可以解决它。请参阅 http://projects.spring.io/spring-data/ 处的文档.该异常是与spring data commons模块版本冲突导致的。 neo4j在4.1.0.RC1版本实现的接口(interface)发生变化，抛出该异常。

要解决，请使用 Spring Data 发布火车 BOM 并将其设置为发布 Hopper-RC1 。由于我使用的是 gradle，所以说明如下，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，
