Package org.springframework.data.redis.connection.jedis

Class JedisConnectionFactory

java.lang.Object

org.springframework.data.redis.connection.jedis.JedisConnectionFactory

All Implemented Interfaces:

org.springframework.beans.factory.DisposableBean, org.springframework.beans.factory.InitializingBean, org.springframework.dao.support.PersistenceExceptionTranslator, RedisConnectionFactory

public class JedisConnectionFactory
extends Object
implements org.springframework.beans.factory.InitializingBean, org.springframework.beans.factory.DisposableBean, RedisConnectionFactory

Connection factory creating Jedis based connections.

JedisConnectionFactory should be configured using an environmental configuration and the client configuration. Jedis supports the following environmental configurations:

• RedisStandaloneConfiguration
• RedisSentinelConfiguration
• RedisClusterConfiguration

This connection factory must be initialized prior to obtaining connections.

Note that JedisConnection and its clustered variant are not Thread-safe and instances should not be shared across threads. Refer to the Jedis documentation for guidance on configuring Jedis in a multithreaded environment.
