菜鸟一枚,请教大神,怎么解决? 代码如下: package com.tp.neo4j.java.examples;

import java.io.File; import org.neo4j.graphdb.GraphDatabaseService; import org.neo4j.graphdb.factory.GraphDatabaseFactory;

public class Neo4jJavaAPIDBOperation { public static void main(String[] args) { GraphDatabaseFactory dbFactory = new GraphDatabaseFactory(); File storeDir = new File(“E:/Program Files/neo4j-community-3.4.1/data/databases/TPNeo4jDB”); GraphDatabaseService db = dbFactory.newEmbeddedDatabase(storeDir); } }


报错如下:

用的maven 下载的jar包?neo4j 3.4.1 用下面版本的jar包

<dependency> <groupId>org.neo4j</groupId> <artifactId>neo4j</artifactId> <version>3.4.0</version> </dependency>

@pangguoming 试过可以,多谢多谢

@pangguoming 我的neo4j是3.2.3 出现一样的问题。是因为版本的原因?
