mTLS/TLS Redis 6 问题 Java

Question

目前我运行 Redis 6 与 ACL 和 mTLS 与 C# 客户端很好。我正在尝试更新我们的 Java 端以也使用 ACL 和 mTLS，但运行遇到了问题。我目前主要专注于 mTLS，并没有取得任何进展。这可能是用户的错误，我在尝试这样做之前已经有 5-6 年没有使用 Java，所以请指教。不确定从这个错误中真正取得什么进展或如何取得进展，我已经完成 google 搜索但没有真正成功。非常感谢任何帮助，我已经很长时间没有做过 Java 所以很可能是问题所在。

Redis 服务器调试日志：

Java代码：

final RedisClient client = RedisClient.create(RedisURI.Builder.redis(hostConfig,portConfig)
                                      .withSsl(true).withVerifyPeer(false).build().toURI().toString());

                        .truststore(new File(redisTruststorePath), redisTruststorePass)
                        .build();
            }
            client.setOptions(ClientOptions.builder().sslOptions(sslOptions).build());
        }
client.connect();

版本：

Lettuce 版本：6.0.0.M1（运行在 windows 本地）
Redis 版本：6.0.5（运行在本地 linux VM 上）

备注：

C# 客户端运行良好，所以怀疑是 Redis 服务器问题。
Redis URI（设置前在我的真实代码中打印）：rediss://localhost:6379

Answer 1

请检查您的 client-side 日志。

16797:M 03 Aug 2020 09:11:11.246 # Error accepting a client connection: (null)

Redis 无法继续连接阶段时会出现上述消息。当 SSL 握手未成功完成时，SSL 安排中会出现此类消息，例如由证书验证失败引起。

查看上面的代码，客户端创建时使用：

RedisClient.create(RedisURI.Builder.redis(hostConfig,portConfig)                                      .withSsl(true).withVerifyPeer(false).build().toURI().toString());

RedisURI 对象被转换为字符串，导致 verifyPeer 标志丢失。

请将您的代码更改为：

RedisClient.create(RedisURI.Builder.redis(hostConfig,portConfig)                                      .withSsl(true).withVerifyPeer(false).build());

删除 .toURI().toString().

Answer 2

如@mp911de mentioned I removed .toURI().toString(); as well as, updated to lettuce-core 6.0.0.RC and started using RESP2 (as suggested here). This resolved my problem. I think the main solution here was switching to RESP2, which again was a suggestion from @mp911de. Thank you for the assistance @mp911de!!
