Spring Data Redis, part of the larger Spring Data family, provides easy configuration and access to Redis from Spring applications. It offers both low-level and high-level abstractions for interacting with the store, freeing the user from infrastructural concerns.

Features

• Connection package as low-level abstraction across multiple Redis drivers(Lettuce and Jedis).

• Exception translation to Spring’s portable Data Access exception hierarchy for Redis driver exceptions.

• RedisTemplate that provides a high-level abstraction for performing various Redis operations, exception translation and serialization support.

• Pubsub support (such as a MessageListenerContainer for message-driven POJOs).

• Redis Sentinel and Redis Cluster support.

• Reactive API using the Lettuce driver.

• JDK, String, JSON and Spring Object/XML mapping serializers.

• JDK Collection implementations on top of Redis.

• Atomic counter support classes.

• Sorting and Pipelining functionality.

• Dedicated support for SORT, SORT/GET pattern and returned bulk values.

• Redis implementation for Spring 3.1 cache abstraction.

• Automatic implementation of Repository interfaces including support for custom query methods using @EnableRedisRepositories.

• CDI support for repositories.

Configure RedisTemplate….

<bean id="jedisConnFactory"
    class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory"
    p:use-pool="true"/>

<!-- redis template definition -->
<bean id="redisTemplate"
    class="org.springframework.data.redis.core.RedisTemplate"
    p:connection-factory-ref="jedisConnFactory"/>

Inject and use RedisTemplate or any of its opsForX() instances….

public class Example {

    // inject the actual template
    @Autowired
    private RedisTemplate<String, String> template;

    // inject the template as ListOperations
    // can also inject as Value, Set, ZSet, and HashOperations
    @Resource(name="redisTemplate")
    private ListOperations<String, String> listOps;

    public void addLink(String userId, URL url) {
        listOps.leftPush(userId, url.toExternalForm());
        // or use template directly
        redisTemplate.boundListOps(userId).leftPush(url.toExternalForm());
    }
}
