Java config + neo4j

[Stacy Tyler Young]

I've been experimenting with using java config for neo4j setup.

@Configuration

@EnableTransactionManagement(mode = AdviceMode.ASPECTJ)

public class DatabaseConfiguration extends Neo4jConfiguration

{

    @Override

    @Autowired

    public void setGraphDatabaseService( GraphDatabaseService service ) {

        super.setGraphDatabaseService( service );

    }

    @Bean(destroyMethod = "shutdown")

    public GraphDatabaseService graphDatabaseService() {

        final Map<String,String> options = new HashMap<String, String>();

        options.put( "enable_remote_shell", "true" );

        return new EmbeddedGraphDatabase( "/usr/share/actual/db", options );

    }

}

Is this valid? It appears to work but I'm wondering if I need to do anything with Neo4jConfiguration? Lastly, any insight on how I can replicate <neo4j:repositories base-package="com.foo" />?

Thanks!

Stacy,

My colleagues kindly pointed me to https://github.com/SpringSource/spring-data-neo4j/blob/master/spring-data-neo4j/src/test/java/org/springframework/data/neo4j/config/Neo4jRepositoriesRegistrarIntegrationTests.java - that should simplify your particular use case.

Ah, thanks so much!

Has this only been used in the context of test case? I'm attempting to use as config from web.xml but not much luck. I may have to pass on this for now anyway as I cannot move to snapshot build. :(

<context-param>

        <param-name>contextConfigLocation</param-name>

        <param-value>

            com.actual.configuration.DatabaseConfiguration.Config

        </param-value>

    </context-param>

public class DatabaseConfiguration extends Neo4jConfiguration

{

    @Configuration

    @EnableNeo4jRepositories(basePackages = "com.acme.repository")

    static class Config extends Neo4jConfiguration

    {

        @Bean

        public GraphDatabaseService graphDatabaseService() {

            final Map<String,String> options = new HashMap<String, String>();

            options.put( "enable_remote_shell", "true" );

            return new EmbeddedGraphDatabase( "/foo", options );

        }

    }

}

I've tried a number of permutations but all end in exceptions at startup.

Stacy,

What concrete errors are you getting?

Would it be possible to recreate the problem in a small test project and share that?

A very non-descriptive exception relating to annotations. My apologies, I meant to include the exception information in that original email. I've since had to revert to xml config due to not being able to use a snapshot build at this point in the project.

I will revisit later this month and report back.
