问题 I am using the Java Bolt driver (1.0.1) and I am wondering there is a way to convert the result to Json (possibly the same as in the REST api)?

I am adding the Neo4j Bolt driver to my application just following the http://neo4j.com/developer/java/ : import org.neo4j.driver.v1.*; Driver driver = GraphDatabase.driver( "bolt://localhost", AuthTokens.basic( "neo4j", "neo4j" ) ); Session session = driver.session(); session.run( "CREATE (a:Person {name:'Arthur', title:'King'})" ); StatementResult result = session.run( "MATCH (a:Person) WHERE a.name = 'Arthur' RETURN a.name AS name, a.title AS title" ); while ( result.hasNext() ) { Record record = result.next(); System.out.println( record.get( "title" ).asString() + " " + record.get("name")
