Re: [Neo4j] Spring-Data neo4j

This should work

Can you share your full config and how you load the spring context files

And what the actual issue is

Hello!

 

I'm working in a project related with neo4j. Now I'm trying to use spring-data neo4j and I have a big problem. My problem is about spring-data neo4j configuration. When I implement my app, I have to set some mapped-files size to launch  tests, and this configuration is never loaded.

I try to implement a bean like this:

<bean id="graphDatabaseService"

class="org.neo4j.kernel.EmbeddedGraphDatabase"

destroy-method="shutdown" scope="singleton">

<constructor-arg value="target/db" />

<constructor-arg>

<map>

<entry key="use_memory_mapped_buffers" value="true" />

<entry key="cache_type" value="none" />

<entry key="neostore.nodestore.db.mapped_memory" value="10M" />

<entry key="neostore.propertystore.db.mapped_memory" value="40M" />

<entry key="neostore.relationshipstore.db.mapped_memory"

value="2G" />

<entry key="neostore.propertystore.db.index.keys.mapped_memory"

value="5M" />

<entry key="neostore.propertystore.db.index.mapped_memory"

value="5M" />

<entry key="neostore.propertystore.db.strings.mapped_memory"

value="1M" />

<entry key="neostore.propertystore.db.arrays.mapped_memory"

value="0M" />

</map>

</constructor-arg>

<neo4j:config graphDatabaseService="graphDatabaseService" />

and, on the other hand, I try to read from a neo4j.properties or graph.db file but neither works.

I'm looking for a solution that allows me set neo4j configuration, if someone can help me I'll be grateful.

Thanks a lot.

This is my test declaration:

@RunWith(SpringJUnit4ClassRunner.class)

@ContextConfiguration

public class GraphTest {

//    @Value(value = "${spe.depth}")

    private int maxDepth = 2;

    private int TOTAL_IDS = 10000;

    

    @Autowired

    private GraphDatabaseService graphDatabaseService;

then, I use graphDatabaseService to getIndex().

what is the complete content of your:

GraphTest-context.xml ?

And how do you check that the config was not used?

This is my .xml:

<neo4j:config graphDatabaseService="graphDatabaseService" />

<neo4j:config storeDirectory="target/db" />

<!-- Package w/ automagic repositories -->

<neo4j:repositories base-package="neo4j" />

</beans>

So, to check it, I saw message.log in db/ that specifies neo4j configuration.

Thanks.

Remove this line

<neo4j:config storeDirectory="target/db" />

This overrides the previous:  <neo4j:config graphDatabaseService="graphDatabaseService" /> 

which is the real one.

I fix it with yours suggestion.

Thanks a lot.
