我们使用RedisTemplate从Redis缓存中获取所有密钥 . 我们使用“扫描”来获取所有密钥 . 我们不直接使用Lettuce或Jedis，我们让RedisTemplate来做 .

当我们将RedisTemplate配置为使用Lettuce时，scan命令将返回所有键 . 当我们将RedisTemplate配置为使用Jedis时，出现了问题，我们看到以下异常：

我们想用一个完整的例子说明问题，所以我们在GitHub https://github.com/michaelweber2/redis-app上创建了一个示例项目 . 该项目使用Java 8，Maven（3），Spring Data Redis（1.8.3.RELEASE），Lettuce（4.3.1.Final）和Jedis（2.9.0） . 该项目已使用Redis服务器3.2.9进行了测试 .

所以问题是为什么我们只有在配置RedisTemplate以使用Jedis时才能获得此Exception，以及我们可以做些什么来使Jedis工作？
