Web服务事务处理系统的研究与实现

Web服务具有良好的互操作性,能有效地支持软件的集成.在集成和交互过程中,Web服务需要事务的支持获得一致和可靠的结果.通过分析Web服务事务处理的基本原理、运行过程和机制,设计和实现了一个Web服务事务处理系统.该系统包括客户端、协调器、参与者和监控管理工具四部分,其中客户端创建、提交或者取消Web服务事务,协调器是管理和控制事务运行的协调中心,参与者是参与事务的Web服务,监控管理工具是提供给管理员的可视化工具.在协调器和参与者的交互过程中使用两阶段提交协议保证事务的原子性和一致性.该系统在处理过程中具有一定的实用性和灵活性,并能满足跨企业商业事务的需求.
