JAVA測試程式碼：

public static void main(String[] args) {

		// 建立Jedis物件，傳遞兩個引數：第一個host為redis伺服器的名稱，第二個為redis伺服器的埠號
		Jedis jedis = new Jedis("192.168.19.101", 6379);
		jedis.auth("123456");
		// 進行設值操作
		jedis.set("username", "李四");
		// 從redis中取值
		String username = jedis.get("username");
		System.out.println("username:" + username);
	}
