Redis使用方法总结

项目地址： https://github.com/redis/jedis

Jedis is a blazingly small and sane Redis java client.

Jedis was conceived to be EASY to use.

Jedis is fully compatible with redis 2.8.x, 3.x.x and above*.

Jedis 是Redis的Java实现的客户端。支持基本的数据类型如：String、Hash、List、Set、Sorted Set。

特点：使用阻塞的I/O，方法调用同步，程序流需要等到socket处理完I/O才能执行，不支持异步操作。Jedis客户端实例不是线程安全的，需要通过连接池来使用Jedis。

JedisPool pool = new JedisPool(new JedisPoolConfig(), "localhost");

/// Jedis implements Closeable. Hence, the jedis instance will be auto-closed after the last statement.try (Jedis jedis = pool.getResource()) { 
 /// ... do stuff here ... for example
  jedis.set("foo", "bar");  String foobar = jedis.get("foo");
  jedis.zadd("sose", 0, "car"); jedis.zadd("sose", 0, "bike"); 
  Set sose = jedis.zrange("sose", 0, -1);
}/// ... when closing your application:pool.close();



//Pipeline使用方式
Jedis jedis = new Jedis();
Pipeline pipeline = jedis.pipelined();
int count = 5000;
for (int i = 0; i < count; i++) {
    String key = "key-" + (i + 1);
    String value = "value-" + (i + 1);
    pipeline.set(key, value);
    pipeline.expire(key, 2);
}
long start = System.currentTimeMillis();
pipeline.syncAndReturnAll();
log.info("Jedis cost:{} ms", System.currentTimeMillis() - start);

优点点：分布式锁，分布式集合，可通过Redis支持延迟队列。

   3.16.2
  

// 1. Create config objectConfig config = new Config();
config.useClusterServers()       
// use "rediss://" for SSL connection
      .addNodeAddress("redis://127.0.0.1:7181");// or read config from fileconfig = Config.fromYAML(new File("config-file.yaml")); 
      
// 2. Create Redisson instance// Sync and Async APIRedissonClient redisson = Redisson.create(config);
// Reactive APIRedissonReactiveClient redissonReactive = redisson.reactive();
// RxJava3 APIRedissonRxClient redissonRx = redisson.rxJava();

// 3. Get Redis based implementation of java.util.concurrent.ConcurrentMap
RMap map = redisson.getMap("myMap");
RMapReactive mapReactive = redissonReactive.getMap("myMap");
RMapRx mapRx = redissonRx.getMap("myMap");

// 4. Get Redis based implementation of java.util.concurrent.locks.Lock
RLock lock = redisson.getLock("myLock");
RLockReactive lockReactive = redissonReactive.getLock("myLock");
RLockRx lockRx = redissonRx.getLock("myLock");

https://lettuce.io/
用于线程安全同步，异步和响应使用，支持集群，Sentinel，管道和编码器。

基于Netty框架的事件驱动的通信层，其方法调用是异步的。Lettuce的API是线程安全的，所以可以操作单个Lettuce连接来完成各种操作。

lettuce使用  https://github.com/lettuce-io/lettuce-core/tree/6.1.4.RELEASE
 
   io.lettuce  
   lettuce-core   
    6.1.4.RELEASE


// 使用
RedisClient redisClient = RedisClient.create("redis://password@localhost:6379/0");
StatefulRedisConnection connection = redisClient.connect();
RedisCommands syncCommands = connection.sync();
syncCommands.set("key", "Hello, Redis!");
connection.close();
redisClient.shutdown();
