操作数据

        Jedis jedis = new Jedis("10.3.151.143", 6379);
        jedis.auth("123");
        String string = jedis.get("list");
        System.out.println(string);

        for(int i=0;i<10000;i++){
          //存map集合
//          map.put("key"+i, "value"+i);
          //存list集合
            list.add("list_"+i);
        }
//      String hmset = jedis.hmset("hamap", map);
//      System.out.println(hmset);

    }
