基于SOA的企业服务总线研究与实现
|
摘要
受开放的网络化应用和面向服务的体系架构(Service-Oriented Architecture,SOA)等诸多因素的影响,企业应用集成正发生着巨大变化。SOA作为一种可优化企业应用的软件基础架构,既能为企业提供一个智能化的基础设施,以降低服务重用的复杂性,又能可靠地集成企业应用中存在的各种技术、协议和应用。因此,本文试图为企业应用建立一种面向服务的中间层,即基于SOA的企业服务总线,以隐藏各种应用和技术带来的底层复杂性,有效地减少应用系统的耦合性,来提高企业应用的互操作性和健壮性。本文的主要内容包括:
(1)在综合现有分析Web服务标准的基础上,分析可灵活实现企业业务集成目标的服务组合的“三横四纵”架构,在服务组合参考模型WSCRM(Web Service Composition Reference Model)的指导下研究了基于SOA的企业应用集成环境,从而明确基于SOA的企业服务总线在企业应用集成中的地位和作用。
(2)提出基于SOA的企业服务总线的原理框架,深入研究传输适配链,服务适配链和核心服务等关键技术,并采用多种SOAP调度策略保证企业服务总线的灵活性和高效性;使用SOAP安全机制来保证企业服务总线的安全性和可信性;采用聚合事务模型为基于SOA的企业服务总线提供事务支持。
(3)采用责任链式设计模式实现一种基于SOA的企业服务总线s-ESB,基于处理器机制来实现传输适配、服务适配和安全服务等,综合运用基于SOA的企业服务总线s-ESB连接湖南电信的部分后台数据和业务流程,包括不同用户数据和遗留应用,促进统一建设、统一管理和统一实现,以适应的灵活多变的电信业务。
Open network application and the service-oriented architecture (SOA) and so on many factor influences,The enterprise is having the immense changes using the integration. SOA has become a new software basic architecture which offers an intelligent infrastructure to reduce the complexity of service reuse and then integrates all kinds of technologies, protocols and applications. Therefore, the thesis intends to construct service-oriented middleware for enterprise applications (i.e. SOA-based Enterprise Service Bus), which can shield the bottom complexity of different applications and technologies, and thus reduce coupling in application systems and enhance the interoperation between them. Main works of the thesis are as follows:
(1) On basis of comprehensive analysis of Web service standards, the thesis puts forward a“three horizontal four vertical”Web service composition framework to implement the enterprise business integration. Under guide of WSCRM (Web Service Composition Reference Model), the thesis designs SOA-based Enterprise Application Integration Environment, and explicitly states the status of SOA-based Enterprise Service Bus in enterprise application integration.
(2) The thesis presents the principle framework of SOA-based Enterprise Service Bus, and researches on transport adaptation chain, service adaptation chain and core services in this framework. Some characteristics of this framework as follows: Depending on multiple SOAP schedule mechanisms to enhance the flexibility and effect of SOA-based Enterprise Service Bus; Using SOAP security mechanisms to guarantee the security and trust of SOA-based Enterprise Service Bus; relying on transaction aggregation to support the transaction of SOA-based Enterprise Service Bus.
(3) For clear clarification of SOA-based Enterprise Service Bus functions in typical enterprise application integration, this thesis adopts the responsibility chain to implementation one of SOA-based Enterprise Service Buses called s-ESB, where some handlers are responsible for transport adaptation, service adaptation and secure service. By comprehensive application of s-ESB to bridge some data and business workflow in Hunan Telecom, it promotes the unified construction, unified management, and unified implementation of Hunan Telecom and adapts to flexible Tele-Service.
