}

以上的測試實例是簡單的key-value，下面試試復(fù)雜的key

List

shardedJedis.lpush("chiwei", "one");
		shardedJedis.lpush("chiwei", "two");
		shardedJedis.lpush("chiwei", "three");
		shardedJedis.lpush("chiwei", "three");
		System.out.println(shardedJedis.llen("chiwei"));
		String str = shardedJedis.lpop("chiwei");
		System.out.println(str);

list添加的元素可重復(fù)

Set不能重復(fù)

shardedJedis.sadd("chiwei", "one");
		shardedJedis.sadd("chiwei", "one");
