RedisKeyValueAdapter (Spring Data Redis 1.8.8.RELEASE API)

java.lang.Object
- org.springframework.data.keyvalue.core.AbstractKeyValueAdapter
- - org.springframework.data.redis.core.RedisKeyValueAdapter

All Implemented Interfaces:

EventListener, org.springframework.beans.factory.Aware, org.springframework.beans.factory.DisposableBean, org.springframework.beans.factory.InitializingBean, org.springframework.context.ApplicationContextAware, org.springframework.context.ApplicationListener<RedisKeyspaceEvent>, org.springframework.data.keyvalue.core.KeyValueAdapter
```
public class RedisKeyValueAdapter
extends org.springframework.data.keyvalue.core.AbstractKeyValueAdapter
implements org.springframework.beans.factory.InitializingBean, org.springframework.context.ApplicationContextAware, org.springframework.context.ApplicationListener<RedisKeyspaceEvent>
```
Redis specific KeyValueAdapter implementation. Uses binary codec to read/write data from/to Redis. Objects are stored in a Redis Hash using the value of RedisHash, the KeyspaceConfiguration or just Class.getName() as a prefix.
Example
```
 
 @RedisHash("persons")
 class Person {
   @Id String id;
   String name;
 }


         prefix              ID
           |                 |
           V                 V
 hgetall persons:5d67b7e1-8640-4475-beeb-c666fab4c0e5
 1) id
 2) 5d67b7e1-8640-4475-beeb-c666fab4c0e5
 3) name
 4) Rand al'Thor
 
 
```
The KeyValueAdapter is not intended to store simple types such as String values. Please use RedisTemplate for this purpose.

1.7
