【摘要】：计算机及通信技术的发展推动着现代物流信息化，，物流信息系统提高了物流管理的效率。在物流信息系统中应用Web服务技术能够很好地解决企业间地区差异和系统开发环境差异的问题，实现Internet（因特网）环境下物流信息系统的无缝集成，提高系统的可扩充性。而在Web服务中使用事务技术，可以有效地保证操作结果的一致性，提高系统运行的可靠性。解决Web服务事务协调的问题，是近年来研究的热点问题，也是企业应用的需求。本文针对面向服务的物流信息系统的特点，提出一个基于抽象服务的Web服务事务协调模型。该模型扩展了现有的Web服务事务协调协议，可以基于向前恢复策略进行内部补偿处理，同时通过补偿接口实现了外部补偿处理。另外，通过定义多样化的补偿规则，可以很容易增添多种补偿策略，实现灵活的补偿处理。该模型主要由客户端、事务协调器、抽象服务、适配器和参与者五个部分组成，根据预定义在抽象服务中的补偿规则进行事务的补偿处理，能够提高事务的成功率。最后通过一个物流应用实例，验证了模型的有效性。
[Abstract]:The development of computer and communication technology promotes the modern logistics information. Logistics information system improves the efficiency of logistics management. The application of Web service technology in logistics information system can solve the problems of regional differences among enterprises and system development environment differences. To realize the seamless integration of logistics information system in Internet (Internet) environment and to improve the scalability of the system. However, the use of transaction technology in Web services can effectively ensure the consistency of operation results. To improve the reliability of the system and to solve the problem of Web service transaction coordination is a hot issue in recent years, and it is also the requirement of enterprise application. According to the characteristics of service-oriented logistics information system, this paper proposes a Web services transaction coordination model based on abstract services, which extends the existing Web services transaction coordination protocol. The internal compensation processing can be based on the forward recovery strategy, and the external compensation processing can be realized through the compensation interface. In addition, by defining a variety of compensation rules, it is easy to add many kinds of compensation strategies. The model consists of five parts: client, transaction coordinator, abstract service, adapter and participant. Finally, a logistics application example is given to verify the validity of the model.
