首先，定義了一個統一的接口，以支持不同操作系統不同實現的透明切換：

/**

*生成機器碼的接口，不同平臺有不同實現

* @author 楊尚川

*/

public interface SequenceService {

/**

* 獲取機器碼

* @return? 機器碼

*/

public String getSequence();

}

其次，定義了一個抽象類，實現了一些通用的功能，如生成MD5摘要、將很長的字符串以固定的位數分割開，以便于人類閱讀(如將機器碼 71F5DA7F495E7F706D47F3E63DC6349A 每4個一組，以-分割為71F5-DA7F-495E-7F70-6D47-F3E6-3DC6-349A)、利用sigar來生成機器碼。這里需要在pom.xml中加入sigar依賴。
