Neo4j Spatial causes lifecycle exception

Question

So I am trying to get my head around Neo4j Spatial. I wrote the following code:

public static void main(String[] args) {
    GraphDatabaseService graphDb = new GraphDatabaseFactory().newEmbeddedDatabase("var/geo");
    SpatialDatabaseService spatialDb = new SpatialDatabaseService(graphDb);
    EditableLayer runningLayer = (EditableLayer) spatialDb.getOrCreateLayer("running", SimplePointEncoder.class, EditableLayerImpl.class, "lon:lat");

    Node ship = null;
    try(Transaction tx = graphDb.beginTx();) {
        ship = graphDb.createNode(MyLabels.Ship);
        ship.setProperty("Name", new String("Toms Powerboat"));
        tx.success();
    }
    routeGenerator(graphDb, runningLayer, ship);
    graphDb.shutdown();
}


private static void routeGenerator(GraphDatabaseService graphDb, EditableLayer runningLayer, Node node){

    final long startTime = System.currentTimeMillis();
    try(
            Transaction tx = graphDb.beginTx();
            ){
        Coordinate start = new Coordinate(Math.random()*10, Math.random()*10);
        for(int i=0; i<200; i++){
            SpatialDatabaseRecord torecord = runningLayer.add(runningLayer.getGeometryFactory().createPoint(start));
            torecord.setProperty("Time", (System.currentTimeMillis() - startTime)*10000000);
            torecord.getGeomNode().createRelationshipTo(node, RelTypes.hasLocation);
            start = new Coordinate((start.x + 0.1), start.x+Math.random()*0.2);
        }

        tx.success();


    }
}

This appears to work the first time that I run it, but if I try to run it a second time I get :

So I understand that this is usually some kind of versioning, so below is the maven dependencies that I have (among many others) from the effective POM.

<dependency>
  <groupId>org.neo4j</groupId>
  <artifactId>neo4j-spatial</artifactId>
  <version>0.13-neo4j-2.0.1</version>
  <scope>compile</scope>
</dependency>
<dependency>
  <groupId>org.neo4j</groupId>
  <artifactId>neo4j</artifactId>
  <version>2.0.1</version>
  <scope>compile</scope>
</dependency>

PS: I would also appreciate understanding why the Java code is not being parsed by SO with the nice highlighting.

Answer 1

This turned out to be a maven problem.

By changing the repositories to:

<repository>
        <id>neo4j-contrib-releases</id>
        <url>https://raw.github.com/neo4j-contrib/m2/master/releases</url>
        <releases>
            <enabled>true</enabled>
        </releases>
        <snapshots>
            <enabled>false</enabled>
        </snapshots>
    </repository>
    <repository>
        <id>neo4j-contrib-snapshots</id>
        <url>https://raw.github.com/neo4j-contrib/m2/master/snapshots</url>
        <releases>
            <enabled>false</enabled>
        </releases>
        <snapshots>
            <enabled>true</enabled>
        </snapshots>
    </repository>

And the dependencies to:

 <dependency>
        <groupId>org.neo4j</groupId>
        <artifactId>neo4j-spatial</artifactId>
        <version>0.12-neo4j-2.0.2</version>
    </dependency>
<dependency>
        <groupId>org.neo4j</groupId>
        <artifactId>neo4j</artifactId>
        <version>2.0.2</version>
    </dependency>

The problem went away. I had previously been using https://mvnrepository.com/artifact/org.neo4j/neo4j-spatial as my maven repository, and it seems these versions are somehow not compatible.

Answer 2

This is not related to neo4j spatial. It seems your neo4j dependencies have been upgraded to a new version. Therefore you datastore need to be upgraded as well.

PLEASE MAKE SURE TO MAKE A BACKUP COPY PRIOR TO UPGRADING. Datastore downgrades are not supported.

To perform the datastore upgrade create your GraphDatabaseService like this:

GraphDatabaseService graphDb = new GraphDatabaseFactory()
  .newEmbeddedDatabaseBuilder("var/geo")
  .setConfig("allow_store_upgrade", "true")
  .newGraphDatabase();
