从 SDN 4.0 迁移到 SDN 4.1.RC1 的 GraphQueryLookupStrategy.resolveQuery 异常 [英] GraphQueryLookupStrategy.resolveQuery exception on migration from SDN 4.0 to SDN 4.1.RC1
问题描述
我正在将我的应用程序迁移到使用 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，以正确使用 HTTPDriver 到我的远程服务器 (localhost:7474)，并且在启动应用程序时，我在尝试加载 spring 上下文时，我的存储库之一出现以下错误.
I am in the process of migrating my application to use SDN 4.1.0.RC1 but have encountered a few issues after trying to boot the application. I have made the necessary configuration changes to correctly use the HTTPDriver to my remote server (localhost:7474) and when booting the application I get the following error with one of my repositories while attempting to load the spring context.

这个好像要哭的vanilia仓库
This is the vanilia repository that seems to be crying
@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数据版本和neo4j版本之间的脱节.
It looks like it could be a disconnect between the version of spring data and spring data neo4j.

看来我所拥有的 QueryLookupStrategy 正在期待一个方法 RepositoryQuery resolveQuery(Method method, RepositoryMetadata metadata, NamedQueries namedQueries); 被实现，但显然它不是.我认为这现在是一个依赖问题，并将进一步调查我需要符合 SDN 的 Spring Data 版本
It appears the QueryLookupStrategy I have is expecting a method RepositoryQuery resolveQuery(Method method, RepositoryMetadata metadata, NamedQueries namedQueries); to be implemented which clearly it is not. I assume this is now a dependency issue and will investigate further with the version of Spring Data I need to be compliant with SDN

推荐答案
好的，所以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 http://projects.spring.io/spring-data/ 上的文档.此异常是由与 spring 数据公共模块的版本冲突引起的.Neo4j在4.1.0.RC1版本中实现的接口发生了变化，因此抛出了这个异常.
Okay, so if you run into this issue there is a pretty straight forward way to resolve it. Please see the documentation at http://projects.spring.io/spring-data/ . This exception was caused by version conflicts with the spring data commons module. The interface that neo4j implements in version 4.1.0.RC1 has changed and thus this exception is thrown.
要解决使用 Spring Data 发布火车 BOM 并将其设置为发布 Hopper-RC1.由于我使用 gradle，因此说明如下，但您也可以在上面的链接中找到它们.
To Resolve use the Spring Data release train BOM and set it to release Hopper-RC1 . Since I use gradle the instructions are below but you can also find them at the link above.
