Redis的Java客户端Jedis

Jedis所需要的jar包

Commons-pool-1.6.jar

Jedis-2.1.0.jar

用windows中的Eclipse连接虚拟机的Redis的注意事项

禁用Linux的防火墙：

临时禁用：service iptables stop

关闭开机自启：chkconfig iptables off

redis.conf中注释掉bind 127.0.0.1（61行） ,然后 protect-mode（80行）设置为 no。

Jedis测试连通性

public class Demo01 {
  public static void main(String[] args) {
    //连接本地的 Redis 服务
    Jedis jedis = new Jedis("127.0.0.1",6379);
    //查看服务是否运行，打出pong表示OK
    System.out.println("connection is OK==========>: "+jedis.ping());
  }
}

Jedis-API: Key

//key
     Set<String> keys = jedis.keys("*");
     for (Iterator iterator = keys.iterator(); iterator.hasNext();) {
       String key = (String) iterator.next();
       System.out.println(key);
     }
     System.out.println("jedis.exists====>"+jedis.exists("k2"));
     System.out.println(jedis.ttl("k1"));
      

Jedis-API: String

     System.out.println(jedis.get("k1"));
     jedis.set("k4","k4_Redis");
     System.out.println("----------------------------------------");
     jedis.mset("str1","v1","str2","v2","str3","v3");
     System.out.println(jedis.mget("str1","str2","str3"));

Jedis-API: List

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

Jedis-API: set

     jedis.sadd("orders","jd001");
     jedis.sadd("orders","jd002");
     jedis.sadd("orders","jd003");
     Set<String> set1 = jedis.smembers("orders");
     for (Iterator iterator = set1.iterator(); iterator.hasNext();) {
       String string = (String) iterator.next();
       System.out.println(string);
     }
     jedis.srem("orders","jd002");

Jedis-API: hash

     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","atguigu");
     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-API: zset

     jedis.zadd("zset01",60d,"v1");
     jedis.zadd("zset01",70d,"v2");
     jedis.zadd("zset01",80d,"v3");
     jedis.zadd("zset01",90d,"v4");
     Set<String> s1 = jedis.zrange("zset01",0,-1);
     for (Iterator iterator = s1.iterator(); iterator.hasNext();) {
       String string = (String) iterator.next();
       System.out.println(string);
     }
