1.redisTemplate类所在的包路径：

org.springframework.data.redis.core.RedisTemplate

2.redisTemplate序列化，需要序列化四个地方，keySerializer， valueSerializer，hashKeySerializer，hashValueSerializer：

@Nullable
private RedisSerializer keySerializer = null;
@Nullable
private RedisSerializer valueSerializer = null;
@Nullable
private RedisSerializer hashKeySerializer = null;
@Nullable
private RedisSerializer hashValueSerializer = null;

3.RedisTemplate可以通过什么方法返回什么对象对数据进行操作？

3.1.常用的获取操作数据的对象方法，opsForValue()，opsForHash()，opsForList()，opsForSet()，opsForZSet()，opsForStream()，opsForGeo()，如下：

3.2.返回的操作对象类型：ValueOperations，ListOperations，SetOperations，StreamOperations，ZSetOperations，GeoOperations，HyperLogLogOperations，ClusterOperations。如下：

private final ValueOperations<K, V> valueOps = new DefaultValueOperations(this);
private final ListOperations<K, V> listOps = new DefaultListOperations(this);
private final SetOperations<K, V> setOps = new DefaultSetOperations(this);
private final StreamOperations<K, ?, ?> streamOps = new DefaultStreamOperations(this, ObjectHashMApper.getSharedInstance());
private final ZSetOperations<K, V> zSetOps = new DefaultZSetOperations(this);
private final GeoOperations<K, V> geoOps = new DefaultGeoOperations(this);
private final HyperLogLogOperations<K, V> hllOps = new DefaultHyperLogLogOperations(this);
private final ClusterOperations<K, V> clusterOps = new DefaultClusterOperations(this);
