Hi @kev205, which module are you trying to integrate?

[kev205]

Hello @scordio thanks,
I want to build batch job for my neo4j data so it is spring-batch-neo4j

[kev205]

that is my pom.xml:

<dependency>
	<groupId>org.springframework.batch.extensions</groupId>
	<artifactId>spring-batch-neo4j</artifactId>
	<version>0.1.0</version>
</dependency>

The resolver cannot find other version than the 0.1.0

[scordio]

That's correct, version 0.1.0 is the latest version published.

Are you facing any issues with this version?

[kev205]

Yes
My app is a reactive app. This is my neo4j config:

@Configuration
@EnableReactiveNeo4jRepositories(basePackages = "com.orion.xchange.goods.repositories")
@EnableReactiveNeo4jAuditing
public class Neo4jConfig {
    @Bean(ReactiveNeo4jRepositoryConfigurationExtension.DEFAULT_TRANSACTION_MANAGER_BEAN_NAME)
    public ReactiveTransactionManager reactiveTransactionManager(Driver driver,
            ReactiveDatabaseSelectionProvider databaseNameProvider) {
        return new ReactiveNeo4jTransactionManager(driver, databaseNameProvider);
    }

    @Bean
    org.neo4j.cypherdsl.core.renderer.Configuration cypherDslConfiguration() {
        return org.neo4j.cypherdsl.core.renderer.Configuration.newConfig()
                .withDialect(Dialect.NEO4J_5).build();
    }

    @Bean
    ReactiveAuditorAware<String> reactiveAuditorAware() {
        return () -> ReactiveSecurityContextHolder.getContext()
                .map(SecurityContext::getAuthentication)
                .filter(Authentication::isAuthenticated)
                .map(Authentication::getName);
    }

    @Bean
    public Neo4jConversions neo4jConversions() {
        Set<GenericConverter> additionalConverters = Set.of(new ImageDTOToValueConverter(),
                new Neo4jRatesToUserRateConverter());
        return new Neo4jConversions(additionalConverters);
    }
}

Now the current version ask me for a sessionFactory but i don't know how to get it. i have tried anything without success

[kev205]

And this is the configuration of spring batch:

@Configuration
@EnableBatchProcessing(tablePrefix = "BATCH_", maxVarCharLength = 1000, isolationLevelForCreate = "SERIALIZABLE")
public class BacthConfig {

    @Value("${spring.neo4j.uri}")
    private String uri;

    @Value("${spring.neo4j.authentication.username}")
    private String username;

    @Value("${spring.neo4j.authentication.password}")
    private String password;

    @Bean
    public SessionFactory sessionFactory() {
        String[] packagesToScan = { "com.orion.xchange.goods.entities" };

        org.neo4j.ogm.config.Configuration configuration = new org.neo4j.ogm.config.Configuration.Builder()
                .uri(uri)
                .credentials(username, password)
                .build();

        return new SessionFactory(configuration, packagesToScan);
    }

    @Bean
    public ItemReader<ArticleBasics> articleItemReader() {
        return new Neo4jItemReaderBuilder<ArticleBasics>()
                .name("articleReader")
                .sessionFactory(sessionFactory())
                .pageSize(50)
                .matchStatement("(a:Article)")
                .whereStatement("a.status <> 'OUT_OF_STOCK'")
                .orderByStatement("a.createdAt DESC")
                .returnStatement("a")
                .targetType(ArticleBasics.class)
                .pageSize(50)
                .build();
    }

    @Bean
    public ItemWriter<Article> articleItemWriter() {
        return new Neo4jItemWriterBuilder<Article>().sessionFactory(sessionFactory())
                .build();
    }
}

Am I doing something wrong? I need some help.

Hi @michael-simons, would you have any hints?

[michael-simons]

Hello.

Warning: I never used Spring Batch in any capacity, so the quality of my answer might not be good.

As far as I know Spring Batch Neo4j used to be build on SDN5 + Neo4j-OGM, at a time at which SDN was only a thin wrapper around Neo4j-OGM the original Neo4j Object mapper. Looking at the version linked above (0.1.0) this is the case in that version.

The configuration @kev205 shared indicates that they are on a recent Spring Boot / Spring Data Neo4j version, which is excellent! SDN6 and higher is an object mapper on its own right, does not use or support Neo4j-OGM.
That however makes it impossible to combine it with this batch extension here, unless a version containing this change

41cbb93

by my colleague @meistermeier has been released.

Hope that helps a bit.

[kev205]

Hello @michael-simons how to get that change?

[kev205]

Hello @michael-simons how to get that change?

[michael-simons]

I have no rights or means to release on that repository, sorry.

[kev205]

So any advise for me? Or i just have to skip the batch feature on my project?

[scordio]

I think we can organize a release with the help of @fmbenhassine.

I can prepare a milestone and collect the unreleased issues and PRs, so that we can publish a meaningful changelog.

Given the newer combination of dependencies, should we release it as 1.0.0 to signal the major change?

Closing in favor of #157.
