Advanced Redis client for thread-safe sync, async, and reactive usage. Supports Cluster, Sentinel, Pipelining, and codecs.http://redis.paluch.biz

Introduction

Lettuce is a scalable thread-safe Redis client for synchronous, asynchronous and reactive usage. Multiple threads may share one connection if they avoid blocking and transactional operations such as BLPOP and MULTI/EXEC. lettuce is built with netty. Supports advanced Redis features such as Sentinel, Cluster, Pipelining, Auto-Reconnect and Redis data models.

This version of lettuce has been tested against Redis and 3.0.

lettuce 3.x works with Java 6, 7 and 8, lettuce 4.x requires Java 8
synchronous, asynchronous and reactive usage
Redis Sentinel
Redis Cluster
SSL and Unix Domain Socket connections
Streaming API
CDI and Spring integration
Codecs (for UTF8/bit/JSON etc. representation of your data)
multiple Command Interfaces

几个常见的使用方法：

1. 连接单机

package com.lambdaworks.examples;import com.lambdaworks.redis.RedisClient;
import com.lambdaworks.redis.RedisConnection;
import com.lambdaworks.redis.RedisURI;/*** @author <a href="mailto:mpaluch@paluch.biz">Mark Paluch</a>* @since 18.06.15 09:17*/
public class ConnectToRedis {public static void main(String[] args) {// Syntax: redis://[password@]host[:port][/databaseNumber]RedisClient redisClient = new RedisClient(RedisURI.create("redis://password@localhost:6379/0"));RedisConnection<String, String> connection = redisClient.connect();System.out.println("Connected to Redis");connection.close();redisClient.shutdown();}
}

2. 连接集群

package com.lambdaworks.examples;import com.lambdaworks.redis.RedisURI;
import com.lambdaworks.redis.cluster.RedisAdvancedClusterConnection;
import com.lambdaworks.redis.cluster.RedisClusterClient;/*** @author <a href="mailto:mpaluch@paluch.biz">Mark Paluch</a>* @since 18.06.15 09:17*/
public class ConnectToRedisCluster {public static void main(String[] args) {// Syntax: redis://[password@]host[:port]RedisClusterClient redisClient = new RedisClusterClient(RedisURI.create("redis://password@localhost:7379"));RedisAdvancedClusterConnection<String, String> connection = redisClient.connectCluster();System.out.println("Connected to Redis");connection.close();redisClient.shutdown();}
}

3. 连接sentinel

package com.lambdaworks.examples;import com.lambdaworks.redis.*;/*** @author <a href="mailto:mpaluch@paluch.biz">Mark Paluch</a>* @since 18.06.15 09:17*/
public class ConnectToRedisUsingRedisSentinel {public static void main(String[] args) {// Syntax: redis-sentinel://[password@]host[:port][,host2[:port2]][/databaseNumber]#sentinelMasterIdRedisClient redisClient = new RedisClient(RedisURI.create("redis-sentinel://localhost:26379,localhost:26380/0#mymaster"));RedisConnection<String, String> connection = redisClient.connect();System.out.println("Connected to Redis using Redis Sentinel");connection.close();redisClient.shutdown();}
}

4.安全的连接

package com.lambdaworks.examples;import com.lambdaworks.redis.*;/*** @author <a href="mailto:mpaluch@paluch.biz">Mark Paluch</a>* @since 18.06.15 09:17*/
public class ConnectToRedisSSL {public static void main(String[] args) {// Syntax: rediss://[password@]host[:port][/databaseNumber]// Adopt the port to the stunnel port in front of your Redis instanceRedisClient redisClient = new RedisClient(RedisURI.create("rediss://password@localhost:6443/0"));RedisConnection<String, String> connection = redisClient.connect();System.out.println("Connected to Redis using SSL");connection.close();redisClient.shutdown();}
}

5. spring集成

package com.lambdaworks.examples;import com.lambdaworks.redis.*;
import org.springframework.beans.factory.annotation.Autowired;/*** @author <a href="mailto:mpaluch@paluch.biz">Mark Paluch</a>* @since 18.06.15 09:31*/
public class MySpringBean {private RedisClient redisClient;@Autowiredpublic void setRedisClient(RedisClient redisClient) {this.redisClient = redisClient;}public String ping() {RedisConnection<String, String> connection = redisClient.connect();String result = connection.ping();connection.close();return result;}
}

使用代码如下：

package com.lambdaworks.examples;import org.springframework.context.support.ClassPathXmlApplicationContext;import com.lambdaworks.redis.RedisClient;
import com.lambdaworks.redis.RedisConnection;/*** @author <a href="mailto:mpaluch@paluch.biz">Mark Paluch</a>* @since 18.06.15 09:17*/
public class SpringExample {public static void main(String[] args) {ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("com/lambdaworks/examples/SpringTest-context.xml");RedisClient client = context.getBean(RedisClient.class);RedisConnection<String, String> connection = client.connect();System.out.println("PING: " + connection.ping());connection.close();MySpringBean mySpringBean = context.getBean(MySpringBean.class);System.out.println("PING: " + mySpringBean.ping());context.close();}}
