重置与远程redis服务器的连接

Question

在red hat linux上安装的redis服务器上尝试基本的set操作.

        JedisPool pool = new JedisPool(new JedisPoolConfig(), HOST, PORT);

        Jedis jedis = null;
        try {
          jedis = pool.getResource();

          System.out.println(jedis.isConnected()); //prints true

          jedis.set("status", "online"); //gets exception

        } finally {
          if (jedis != null) {
            jedis.close();
          }
        }

        pool.destroy();

获得以下异常:

如何解决这个问题？

我有类似的问题。我们的生产 Redis 需要通过 TLS 进行加密连接，而我们的测试系统则不需要。因此，在生产中java.net.SocketException: Connection reset，当我们尝试使用 Jedis 连接时，就会出现这种情况。

要修复它，请使用

JedisPool pool = new JedisPool(new JedisPoolConfig(), HOST, PORT, true);

对于需要 TLS 的连接。
