How to use batch-import of neo4j

Question

I'm totally new of neo4j and maven.

I'm using a batch-import tool to convert my mysql to neo4j. After compiling and converting from .csv, a target file containing graph.db is generated. Does it mean that I have successfully converted my .csv into neo4j? What should I do now?

Hope there is someone who can help me.

Oh, I roughly understand. I should first install the neo4j server on ubuntu and link the path to the target pointing to graph.db — starry
You can either copy your target/graph.db to your /path/to/server/data/graph.db or you can edit conf/neo4j-server.properties to specify the full path to your created db as store-location. But move it somewhere else as the target directory will be cleaned whenever you run mvn clean — Michael Hunger
Make sure that the server is not running when you replace the graph.db — Michael Hunger

You have a couple of options to inspect your converted data.

Java REST server

Download and install the Neo4j server. Connect to it via http://localhost:7474. Launch a cypher query to inspect your data. E.g. START n=node(*) RETURN n;.

Java embedded server

You could write a small java application that connects to your data directory. E.g.

public static void main(String[] args) throws Exception {
    final GraphDatabaseService graphDb = new GraphDatabaseFactory().newEmbeddedDatabase("db");       
    final ExecutionEngine engine = new ExecutionEngine(graphDb);
    System.out.println(engine.execute("START n=node(*) RETURN n").dumpToString());
    graphDb.shutdown();
}
