Java环境下：
1.创建maven 项目
2.导入依赖
<!-- redis -->
<dependency>
<groupId>redis.clients</groupId>
<artifactId>jedis</artifactId>
<version>4.3.2</version>
</dependency>此处使用的是Jedis（提供的api和redis命令高度一致）
3.配置端口转发
防止Redis的端口被黑客攻击 将云服务器的redis端口映射到本地主机中
在xshell中配置：
此时, 访问本地的 8888, 就相当于访问对应服务器的 6379
此时连接成功
一.基本命令：
public static void test(Jedis jedis) {
System.out.println("set 和 get 使用");
//清空数据库
jedis.flushAll();
jedis.set("key","k1");
jedis.set("key2","k2");
jedis.set("key3","k3");
String key = jedis.get("key");
String key2 = jedis.get("key2");
String key3 = jedis.get("key3");
System.out.println("key: " + key);
System.out.println("key2: " + key2);
System.out.println("key3: " + key3);
System.out.println("exists 和 del 使用");
boolean result = jedis.exists("key");
System.out.println("result:" + result);
result = jedis.exists("key1111");
System.out.println("result:" + result);
long del = jedis.del("key", "key2");

jedis.set("key4","k4");
jedis.expire("key4",10);
//休眠5s
try {
Thread.sleep(5000);
} catch (InterruptedException e) {
throw new RuntimeException(e);
}
long ttl = jedis.ttl("key4");
System.out.println("ttl: " + ttl );

System.out.println("rpuhs ,rpop, lpop 使用 ");
jedis.rpush("key2","1","2","3","4","5");
System.out.println("key2 :" + jedis.lrange("key2",0,-1));
System.out.println("lpop key2：" + jedis.lpop("key2"));
System.out.println("rpop key2：" + jedis.rpop("key2"));
System.out.println("llen 使用");
System.out.println("len key2: " + jedis.llen("key2"));

} 
都是一些基本操作，跟在redis操作基本一致，
Spring环境:
创建项目时勾选即可
通过注入的方法拿到StringRedisTemplate操作Redis 相当于刚才的Jedis
将操作Redis的方法分成几个类别，好进一步更好的组织
大体命令基本一致
