Neo4j ExecutionEngine和ExecutionResult已弃用？

Question

In Neo4j's neo4j-2.2.0-M03 version, when I try to import

import org.neo4j.cypher.javacompat.ExecutionEngine; and

import org.neo4j.cypher.javacompat.ExecutionResult;

I get a deprecated warning. I can't seem to find what packages I should use instead...

Answer 1

Wow, I don't see any deprecation warnings, but using

ExecutionEngine engine = new ExecutionEngine(db, StringLogger.wrap(new OutputStreamWriter(System.out)));
ExecutionResult er = engine.execute(query);

gives me huge memory leak. and this is completely ok

GraphDatabaseService graphDb = ...
Result er = graphDb.execute(query);

Answer 2

GraphDatabaseService provides now a direct way to run a Cypher query using GraphDatabaseService.execute() . NB there are two variants of that method one with and one without parameters.
