Apache spark 如何在IDE中将spark连接到neo4j

如果不使用火花壳，是否无法连接火花和Neo4j？我尝试了Neo4jREST API并在Conf文件中找到了一些东西，但是我没有看到任何驱动程序/连接器在两个程序之间建立连接，以便我可以从代码中查询

编辑：这是我遇到的错误

使用此代码尝试建立连接：

val driver: Driver = GraphDatabase.driver("bolt://localhost:7687", 
AuthTokens.basic("neo4j", "password"))
val session = driver.session()

val query = neo.cypher("MATCH (n:Person) RETURN n.name").partitions(5).batch(10000).loadDataFrame()
println(query.show())

session.close()
driver.close()

那么，您需要将“密码”更改为您设置的密码，并确保正确指定了用户名
