What is the correct annotation configuration for Spring data and neo4j

Question

I'm trying to configure Spring-data with Neo4j with an @configuration class but I cannot find any reference material on how to do that properly and I'm running into one issue after the next. Here's what I've pieced together so far:

package reservation.configuration;

import org.neo4j.graphdb.GraphDatabaseService;
import org.neo4j.kernel.EmbeddedGraphDatabase;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.neo4j.config.EnableNeo4jRepositories;
import org.springframework.data.neo4j.repository.GraphRepositoryFactory;
import org.springframework.data.neo4j.support.Neo4jTemplate;
import org.springframework.data.neo4j.support.mapping.Neo4jMappingContext;

@Configuration
@EnableNeo4jRepositories("reservation.repository.neo4j")
public class Neo4jConfig {

    private static final String STORE_ID = "helloworld";

    @Bean
    public GraphDatabaseService graphDatabaseService() {
        return new EmbeddedGraphDatabase(STORE_ID);
    }

    @Bean
    public Neo4jTemplate neo4jTemplate() {
        return new Neo4jTemplate(graphDatabaseService());
    }

    @Bean
    public GraphRepositoryFactory graphRepositoryFactory() {
        return new GraphRepositoryFactory(neo4jTemplate(), neo4jMappingContext());
    }

    @Bean
    public Neo4jMappingContext neo4jMappingContext() {
        return new Neo4jMappingContext();
    }
}

The exception I have when starting the application is this below. Any suggestions?

java.lang.IllegalStateException: No persistence exception translators found in bean factory. Cannot perform exception translation.

Answer 1

I've managed to get it down to this after extending from Neo4jConfiguration:

@Configuration
@EnableNeo4jRepositories("reservation.repository.neo4j")
public class Neo4jConfig extends Neo4jConfiguration {

    private static final String DB_PATH = "/Temp/neo4j";

    @Bean
    public GraphDatabaseService graphDatabaseService() {
        return new EmbeddedGraphDatabase(DB_PATH);
    }
}

And this seems to work just fine.
