Getting WrappingNeoServerBootstrapper無法解析爲類型

Question

我在嵌入式Java中使用neo4j。

我想通過我有的應用程序啓動進程中的服務器管理實例。我無法在Eclipse中編譯應用程序，因爲它表示

「WrappingNeoServerBootstrapper無法解析爲類型」。它無法解析下面的行

private WrappingNeoServerBootstrapper srv;

我很感謝在這個問題上的任何幫助。

請參見下面的I類

    public void StopAdminInstance()

}

你使用像Maven的依賴管理框架有哪些？您必須包含neo4j-server jar，其中包含該Class。

您還需要更新StartAdminInstance有WrappingNeoServerBootstrapper srv = new WrappingNeoServerBootstrapper((AbstractGraphDatabase) graphDb);
