Class StringRedisSerializer

java.lang.Object

org.springframework.data.redis.serializer.StringRedisSerializer

All Implemented Interfaces:

RedisSerializer<String>

public class StringRedisSerializer
extends Object
implements RedisSerializer<String>

Simple String to byte[] (and back) serializer. Converts Strings into bytes and vice-versa using the specified charset (by default UTF-8).

Useful when the interaction with the Redis happens mainly through Strings.

Does not perform any null conversion since empty strings are valid keys/values.
