Java16升级后的“需要Jedis NOAUTH身份验证”-spam

Question

最近，由于客户的要求，我们将我们所有的系统迁移到了java16。所以这是一个不可改变的决定。

现在，在升级之后，我们的jedis连接开始向终端发送垃圾邮件，错误代码如下：

[17:17:31 ERROR]: [redis.clients.jedis.JedisFactory] Error while validating pooled Jedis object.

系统信息：

Debian buster (10) Java版本: 16.0.1 Jedis版本:4.0.0-快照(也尝试过3.6.x和3.5.x)远程服务器的Redis版本: 5.0.3 Commons pool: 2.9.0 (也尝试过2.5.0)

连接代码：

Jedis jedis = null;
try {
    jedisPool = new JedisPool("XXX.XXX.XXX.XXX", XXX, 10000);
    jedis = MasterMind.getInstance().getJedisPool().getResource();
    jedis.auth("<SuperSafePass>");
    jedis.exists("test");
    Bukkit.getLogger().info("Connection build");
} catch (Exception e) {
    e.printStackTrace();
    Bukkit.getLogger().warning("Connection failure");
} finally {
    if (jedis != null)
        jedis.close();
}

如您所见，我的身份验证是正确的。建立连接。大约30秒后，它开始向错误发送垃圾邮件(大约每30秒发送10次)

Answer 1

如果Redis需要口令，则必须在创建JedisPool时使用以下构造函数之一设置口令

public JedisPool(final GenericObjectPoolConfig poolConfig, final String host, int port,
                 int timeout, final String password) { ... }

手动身份验证使用

jedis.auth(...);

在这种情况下不再需要。
