GraphQueryLookupStrategy.resolveQuery exception on migration from SDN 4.0 to SDN 4.1.RC1

Question

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.

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userRepository': Invocation of init method failed; nested exception is java.lang.AbstractMethodError: org.springframework.data.neo4j.repository.query.GraphQueryLookupStrategy.resolveQuery(Ljava/lang/reflect/Method;Lorg/springframework/data/repository/core/RepositoryMetadata;Lorg/springframework/data/repository/core/NamedQueries;)Lorg/springframework/data/repository/query/RepositoryQuery;

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);

}

EDIT

It looks like it could be a disconnect between the version of spring data and spring data neo4j.

The GraphQueryLookupStrategy in question...

}

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

Answer 1

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.

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.

Relevant build script simplified...

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'
    }
}

Cheers,

Steve

Answer 2

Expanding on @Holycowzer's answer for Maven users. Add the following line to your builds POM.xml. Note that this is will sit outside of your main <dependencies /> tag set.

<dependencyManagement>
  <dependencies>
    <dependency>
        <groupId>org.springframework.data</groupId>
        <artifactId>spring-data-releasetrain</artifactId>
        <version>Hopper-SR1</version>
        <type>pom</type>
        <scope>import</scope>
    </dependency>
  </dependencies>
</dependencyManagement>

I noticed some imports broke while doing this, simply add them explicitly as dependencies in your POM and everything should work as expected.
