java.util.Hashtable<Object,Object>

java.util.Properties

org.springframework.data.redis.support.collections.RedisProperties

All Implemented Interfaces:

Serializable, Cloneable, ConcurrentMap<Object,Object>, Map<Object,Object>, BoundKeyOperations<String>, RedisMap<Object,Object>, RedisStore

public class RedisProperties
extends Properties
implements RedisMap<Object,Object>

Properties extension for a Redis back-store. Useful for reading (and storing) properties inside a Redis hash. Particularly useful inside a Spring container for hooking into Spring's property placeholder or PropertiesFactoryBean.

Note that this implementation only accepts Strings - objects of other type are not supported.
