在AWS Lambda函数中访问Neo4j服务器

我在使用Lambda函数访问我的Neo4j数据库时遇到问题。我想建立一个Alexa技能，并且在Alexa技能中，应该可以访问像Neo4j这样的图形数据库。我认为将数据库放入云中（使用GrapheneDB）可以解决这个问题，但现在看起来认证有些问题。在AWS Lambda函数中访问Neo4j服务器

import org.neo4j.driver.v1.*; 
import static org.neo4j.driver.v1.Values.parameters; 

public class DB { 

public static void main(String...args) { 

    Config noSSL = Config.build().withEncryptionLevel(Config.EncryptionLevel.NONE).toConfig(); 

    Driver driver = GraphDatabase.driver("bolt://xyz.dbs.graphenedb.com:24786", AuthTokens.basic("db","pw"), noSSL); 
    try (org.neo4j.driver.v1.Session session = driver.session()) { 
    ... 
    }

此代码的工作在我的IntelliJ IDE，但是当我尝试把这个代码样本lambda函数，发生这些错误：

任何人可以提供帮助的？还是有更好的方法来访问Neo4j DB？

解决了这个问题。只需更改加密设置：

Config SSL = Config.build().withEncryption().toConfig();

也许它可以帮助某人。
