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");result = jedis.exists("key");System.out.println("result:" + result);System.out.println("keys 使用");jedis.set("key","k1");jedis.set("key2","k2");Set<String> keys = jedis.keys("*");System.out.println("keys: " + keys);System.out.println("expire 和 ttl 使用");jedis.set("key4","k4");jedis.expire("key4",10);//休眠5stry {Thread.sleep(5000);} catch (InterruptedException e) {throw new RuntimeException(e);}long ttl = jedis.ttl("key4");System.out.println("ttl: " + ttl );System.out.println("type 使用");jedis.flushAll();jedis.set("String", "1");String type = jedis.type("String");System.out.println("type: "+type);jedis.lpush("list","111","222","333");type = jedis.type("list");System.out.println("type: "+type);jedis.sadd("set","a","b","c");type = jedis.type("set");System.out.println("type: "+type);jedis.zadd("zset",1.0,"zhangsan");type = jedis.type("zset");System.out.println("type: "+type);jedis.hset("hash","f1 ","v1");type = jedis.type("hash");System.out.println("type: "+type);}

 String :

    public static void test(Jedis jedis) {//清空数据库jedis.flushAll();System.out.println("mset 和 mget 使用");jedis.mset("k1","111","k2","222","k3","333");List<String> mget = jedis.mget("k1", "k2", "k3","k4");System.out.println("mget: " +mget);System.out.println("getrange 和 setrange 使用");jedis.set("k4","abcdefgh");String k4 = jedis.getrange("k4", 0, 4);System.out.println("result: " +k4);jedis.setrange("k4",0,"eeee");System.out.println("k4: " +jedis.get("k4"));System.out.println("append 使用");jedis.append("k4","aaaaaa");System.out.println("k4: " + jedis.get("k4"));System.out.println("incr 和 decr 使用");jedis.set("k5","111");System.out.println( "k5: " + jedis.incr("k5"));System.out.println( "k5: " + jedis.decr("k5"));}

 

list使用：

    public static void  test(Jedis jedis) {jedis.flushAll();System.out.println("lpush 和 lrange 使用");jedis.lpush("key","1","2","3","4","5");System.out.println("key:" + jedis.lrange("key",0,-1));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"));}

hash的使用：

    private static void test(Jedis jedis) {jedis.flushAll();System.out.println("hset 和 hget 使用");HashMap<String,String> hash = new HashMap<>();hash.put("f2","v2");hash.put("f3","v3");hash.put("f4","v4");jedis.hset("key",hash);jedis.hset("key","f1","v1");System.out.println("key f1: " +jedis.hget("key", "f1"));System.out.println("key f5: " +jedis.hget("key", "f5"));System.out.println("hexists 使用");Boolean result = jedis.hexists("key","f1");System.out.println("key f1 result: " + result);result = jedis.hexists("key","f5");System.out.println("key f5 result: " + result);System.out.println("hkeys 和 hvals 使用");Set<String> hkeys = jedis.hkeys("key");System.out.println("hkeys： " + hkeys);List<String> hvals = jedis.hvals("key");System.out.println("hvals: " +hvals);System.out.println("hdel 使用");jedis.hdel("key","f1");result = jedis.hexists("key","f1");System.out.println("key f1 result: " + result);System.out.println("hmset 和 hmget 使用");List<String> hmget = jedis.hmget("key", "f1", "f2", "f3");System.out.println("hmget key: " + hmget);}

set的使用：

    public static void test(Jedis jedis) {jedis.flushAll();System.out.println("sadd 和 smembers 使用");jedis.sadd("key","a","b","c","d");Set<String> smembers = jedis.smembers("key");System.out.println("key: " +smembers);System.out.println("sismember ， scard ， spop  使用");boolean result = jedis.sismember("key", "a");System.out.println("result: " + result);long len  = jedis.scard("key");System.out.println("key len: " +len);jedis.spop("key");System.out.println("key len: " +jedis.scard("key"));System.out.println("sinter 和 sinterstore");jedis.sadd("key2","1","2","3","4","5");jedis.sadd("key3","3","4","5","6","7");System.out.println("[key2 key3]sinter: "+ jedis.sinter("key2","key3"));long sinterstore = jedis.sinterstore("key4", "key2", "key3");System.out.println("sinterstore: " + sinterstore);System.out.println("key4: " + jedis.smembers("key4"));}

zset的使用:

    public static void test(Jedis jedis) {jedis.flushAll();System.out.println("zadd 和 zrange 使用");jedis.zadd("key",10.0,"zhangsan");Map<String ,Double> hash = new HashMap<>();hash.put("lisi",20.0);hash.put("wangwu",30.0);jedis.zadd("key",hash);List<String> members = jedis.zrange("key", 0, -1);System.out.println("members: "+members);List<Tuple> key = jedis.zrangeWithScores("key", 0, -1);System.out.println("key: " + key);System.out.println("zcard , zscore 使用");long len = jedis.zcard("key");System.out.println("len key: " +len);Double score  =  jedis.zscore("key","zhangsan");System.out.println("score: " + score);System.out.println("zrem , zrank 使用");Long zrank = jedis.zrank("key", "lisi");System.out.println("lisi rank: " + zrank);jedis.zrem("key","zhangsan");System.out.println("lisi rank: " + jedis.zrank("key", "lisi"));}

 

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
