neo4j - 无依赖满足类型接口 org.neo4j.graphdb.GraphDatabaseService

Question

我们想将我们的 neo4J 集群从 neo4J 3.4.x 升级到 neo4J 3.5.2，但现在我们面临以下问题：

这是代码片段：

public class RegisterTransactionEventHandlerExtensionFactory extends KernelExtensionFactory<RegisterTransactionEventHandlerExtensionFactory.Dependencies> {

    @Override
    public Lifecycle newInstance(KernelContext kernelContext, final Dependencies dependencies) throws Throwable {
        return new LifecycleAdapter() {

            private SilaTransactionEventHandler handler;
            private ExecutorService executor;

            @Override
            public void start() throws Throwable {
                executor = Executors.newFixedThreadPool(2);
                handler = new SilaTransactionEventHandler(dependencies.getGraphDatabaseService(), executor);
                dependencies.getGraphDatabaseService().registerTransactionEventHandler(handler);
            }

            @Override
            public void shutdown() throws Throwable {
                executor.shutdown();
                dependencies.getGraphDatabaseService().unregisterTransactionEventHandler(handler);
            }
        };
    }

    interface Dependencies {
        GraphDatabaseService getGraphDatabaseService();
    }

    public RegisterTransactionEventHandlerExtensionFactory() {
        super("registerTransactionEventHandler");
    }

}

neo4J 3.4.x 没有问题，所以我肯定在最新版本中有一些变化。有没有人有同样的问题？谢谢。

Answer 1

Here is the solution which I got from neo4J community forum:

https://community.neo4j.com/t/no-dependency-satisfies-type-interface-org-neo4j-graphdb-graphdatabaseservice/4682

The only change which I had to do:

public RegisterTransactionEventHandlerExtensionFactory() {
    super(ExtensionType.DATABASE, "registerTransactionEventHandler");
}
