1、Jedis客戶端

https://redis.io/clients

2、Jedis源碼包與使用介紹

https://github.com/xetorthio/jedis

3、項目中使用

通過maven引入Jedis的依賴包

<dependency><groupId>redis.clients</groupId><artifactId>jedis</artifactId><version>2.9.0</version><type>jar</type><scope>compile</scope> </dependency>

4、Jedis的使用

創建Jedis對象，set方法存儲key-value值，get方法獲取key對應的值。主要是用于單個redis。

Jedis jedis = new Jedis("192.168.56.180", 6379); jedis.set("Jedis", "Hello Work!"); System.out.println(jedis.get("Jedis")); jedis.close();

?

這里是使用IDEA編輯器對Jedis類結構的一個關系圖，從圖中看出Jedis繼承BinaryJedis，實現多個接口。

每一個接口都代表了一類Redis命令，例如JedisCommands中包含了SET GET等命令，MultiKeyCommands中包含了針對多個Key的MSET MGET等命令。

5、JedisCluster的使用

Jediscluster類圖和jedis類圖大致一樣，不過jedisCluster有一些命令是不可用的。比如BinaryJedisCluster類被作廢的命令。主要是用在集群中。
