exec

List<Object> exec(org.springframework.data.redis.serializer.RedisSerializer<?> valueSerializer)

Execute a transaction, using the provided RedisSerializer to deserialize any results that are byte[]s or Collections of byte[]s. If a result is a Map, the provided RedisSerializer will be used for both the keys and values. Other result types (Long, Boolean, etc) are left as-is in the converted results. Tuple results are automatically converted to TypedTuples.

Parameters:

valueSerializer - The RedisSerializer to use for deserializing the results of transaction exec

Returns:

The deserialized results of transaction exec
