在 AWS Lambda 函数中访问 Neo4j 服务器

Question

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，并且在那个 Alexa 技能中应该可以访问像 Neo4j 这样的图形数据库。本来以为把DB放到云端（用GrapheneDB）就可以解决这个问题了，现在看来认证有问题

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()) {
    ...
    }

此代码在我的 IntelliJ IDE 中有效，但当我尝试将此代码放入示例 Lambda 函数时，出现以下错误：

有人可以帮忙吗？或者有更好的方法来访问 Neo4j 数据库吗？

Answer 1

问题解决了。只需更改加密设置：

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

也许对某人有帮助。
