1 Jedis所需要的jar包

在pom文件中引入依赖

redis.clients
jedis
3.2.0

2 连接Redis注意事项

禁用Linux的防火墙：Linux(CentOS7)里执行命令
systemctl stop/disable firewalld.service
redis.conf中注释掉bind 127.0.0.1 ,然后 protected-mode no

3 Jedis常用操作

3.1 创建动态的工程

创建一个maven工程、过程略

3.2 创建测试程序

填写虚拟机的ip+端口。如果redis设置了密码，需要添加

/*** @author zyz* @version 1.0* @data 2022/12/21 21:12* @Description:*/
public class RedisTest {public static void main(String[] args) {Jedis jedis = new Jedis("192.168.202.211", 6379);jedis.auth("root");String pong = jedis.ping();System.out.println("成功连接："+pong);jedis.close();}
}

3.3 测试结果

3.4 测试相关数据类型

3.4.1 Jedis-API: Key

这里省略了连接过程

        jedis.set("k1", "v1");jedis.set("k2", "v2");jedis.set("k3", "v3");Set keys = jedis.keys("*");System.out.println(keys.size());for (String key : keys) {System.out.println(key);}System.out.println(jedis.exists("k1"));System.out.println(jedis.ttl("k1"));System.out.println(jedis.get("k1"));

测试结果

3.4.2 Jedis-API: String

     jedis.mset("str1","v1","str2","v2","str3","v3");System.out.println(jedis.mget("str1","str2","str3"));

3.4.3 Jedis-API: List

       List list = jedis.lrange("mylist",0,-1);for (String element : list) {System.out.println(element);}

3.4.4 Jedis-API: set

   jedis.sadd("orders", "order01");jedis.sadd("orders", "order02");jedis.sadd("orders", "order03");jedis.sadd("orders", "order04");Set smembers = jedis.smembers("orders");for (String order : smembers) {System.out.println(order);}jedis.srem("orders", "order02");

3.4.5 Jedis-API: hash

        jedis.hset("hash1","userName","lisi");System.out.println(jedis.hget("hash1","userName"));Map map = new HashMap();map.put("telphone","13810169999");map.put("address","atguigu");map.put("email","abc@163.com");jedis.hmset("hash2",map);List result = jedis.hmget("hash2", "telphone","email");for (String element : result) {System.out.println(element);}

3.4.5 Jedis-API: zset

        jedis.zadd("zset01", 100d, "z3");jedis.zadd("zset01", 90d, "l4");jedis.zadd("zset01", 80d, "w5");jedis.zadd("zset01", 70d, "z6");Set zrange = jedis.zrange("zset01", 0, -1);for (String e : zrange) {System.out.println(e);}
