该功能将包含在即将发布的Spring Data Redis
2.1版本中。您将配置LettuceConnectionFactory类似于：

    LettuceClientConfiguration configuration = LettuceClientConfiguration.builder()
                                                    .readFrom(ReadFrom.SLAVE)
                                                    .build();

    LettuceConnectionFactory factory = new LettuceConnectionFactory(new RedisStandaloneConfiguration("x", 6379),
                                                    configuration);

Lettuce从静态（不由Redis Sentinel管理）设置中自动发现主服务器和从服务器。
