The milestone releases of Spring Data Graph are available from the dedicated milestone repository. Neo4j releases and milestones are available from Maven Central.

The dependency on spring-data-neo4j should transitively pull in Spring Framework (core, context, aop, aspects, tx), Aspectj, Neo4j and Spring Data Commons. If you already use these (or different versions of these) in your project, then include those dependencies on your own.

<dependency>
  <groupId>org.springframework.data</groupId>
  <artifactId>spring-data-neo4j</artifactId>
  <version>1.0.0.M5</version>
</dependency> 

<dependency>
  <groupId>org.aspectj</groupId>
  <artifactId>aspectjrt</artifactId>
  <version>1.6.11.RELEASE</version>
</dependency>
						

As Spring Data Graph uses AspectJ for build time aspect weaving of your entities, it is necessary to add the aspectj-plugin to the build phases. The plugin has its own dependencies. You also need to explicitely specifiy libraries containing aspects (spring-aspects and spring-data-neo4j)

  <groupId>org.codehaus.mojo</groupId>
  <artifactId>aspectj-maven-plugin</artifactId>
  <version>1.0</version>
  <dependencies>
    <!-- NB: You must use Maven 2.0.9 or above or these are ignored (see MNG-2972) -->

To simplify the configuration we provide a xml namespace datagraph that allows configuration of any Spring Data Graph project with a single line of xml code. There are three possible parameters. You can use storeDirectory or the reference to graphDatabaseService alternatively. For cross-store configuration just refer to an entityManagerFactory.

    <bean id="graphDatabaseService" class="org.neo4j.kernel.EmbeddedGraphDatabase" 
      destroy-method="shutdown">
         <constructor-arg index="0" value="target/config-test" />
    </bean>

    <datagraph:config graphDatabaseService="graphDatabaseService"/>
                    

  <context:annotation-config/>

    <datagraph:config storeDirectory="target/config-test"
      entityManagerFactory="entityManagerFactory"/>

    <bean class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"
      id="entityManagerFactory">
        <property name="dataSource" ref="dataSource"/>
        <property name="persistenceXmlLocation" value="classpath:META-INF/persistence.xml"/>
    </bean>
                    

You can also configure Spring Data Graph using Java based bean metadata.

To help configure Spring Data Graph using Java based bean metadata the class Neo4jConfiguration is registerd with the context either explicitly in the XML config or via classpath scanning for classes that have the @Configuration annotation. The only thing that must be provided in addition is the GraphDatabaseService configured with a datastore directory. The example below shows using XML to register the Neo4jConfiguration @Configuration class as well as Spring's ConfigurationClassPostProcessor that transforms the @Configuration class to bean definitions.

    <beans>
    ...

        <tx:annotation-driven mode="aspectj" transaction-manager="transactionManager"/>
        <bean class="org.springframework.data.graph.neo4j.config.Neo4jConfiguration"/>

        <bean class="org.springframework.context.annotation.ConfigurationClassPostProcessor"/>

        <bean id="graphDatabaseService" class="org.neo4j.kernel.EmbeddedGraphDatabase"
              destroy-method="shutdown" scope="singleton">
            <constructor-arg index="0" value="target/config-test"/>
        </bean>
    ...
    </beans>
