七、Jedis使用

1、Redis_Jedis_测试

1、Jedis所需要的jar包

<dependency>
    <groupId>redis.clients</groupId>
    <artifactId>jedis</artifactId>
    <version>3.2.0</version>
</dependency>

2、Jedis常用操作

1、创建测试程序

public static void main(String[] args) {
    Jedis jedis = new Jedis("42.193.37.228", 6379);
    String pong = jedis.ping();
    System.out.println("连接成功：" + pong);
    jedis.close();
}

2、Jedis - key

public static void main(String[] args) {
    Jedis jedis = new Jedis("42.193.37.228", 6379);
    jedis.set("k1", "v1");
    jedis.set("k2", "v2");
    jedis.set("k3", "v3");
    Set<String> 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"));
    jedis.close();
}

3、Jedis - String

public static void main(String[] args) {
    Jedis jedis = new Jedis("42.193.37.228", 6379);
    jedis.mset("str1","v1","str2","v2","str3","v3");
    System.out.println(jedis.mget("str1","str2","str3"));
    jedis.close();
}

4、Jedis - List

public static void main(String[] args) {
    Jedis jedis = new Jedis("42.193.37.228", 6379);
    List<String> list = jedis.lrange("mylist",0,-1);
    for (String element : list) {
        System.out.println(element);
    }
    jedis.close();
}

5、Jedis - Set

public static void main(String[] args) {
    Jedis jedis = new Jedis("42.193.37.228", 6379);
    jedis.sadd("orders", "order01");
    jedis.sadd("orders", "order02");
    jedis.sadd("orders", "order03");
    jedis.sadd("orders", "order04");
    Set<String> smembers = jedis.smembers("orders");
    for (String order : smembers) {
        System.out.println(order);
    }
    jedis.srem("orders", "order02");
    jedis.close();
}

6、Jedis - Hash

public static void main(String[] args) {
    Jedis jedis = new Jedis("42.193.37.228", 6379);
    jedis.hset("hash1","userName","lisi");
    System.out.println(jedis.hget("hash1","userName"));
    Map<String,String> map = new HashMap<String,String>();
    map.put("telphone","13810169999");
    map.put("address","xue");
    map.put("email","abc@163.com");
    jedis.hmset("hash2",map);
    List<String> result = jedis.hmget("hash2", "telphone","email");
    for (String element : result) {
        System.out.println(element);
    }
    jedis.close();
}

7、Jedis - Zset

public static void main(String[] args) {
    Jedis jedis = new Jedis("42.193.37.228", 6379);
    jedis.zadd("zset01", 100d, "z3");
    jedis.zadd("zset01", 90d, "l4");
    jedis.zadd("zset01", 80d, "w5");
    jedis.zadd("zset01", 70d, "z6");

    Set<String> zrange = jedis.zrange("zset01", 0, -1);
    for (String e : zrange) {
        System.out.println(e);
    }
    jedis.close();
}
