【摘要】：随着企业SOA应用的不断发展,要求IT系统也必须能够满足业务的变更需要。SOA从业务的视角来指导企业IT系统建设,更易于理解业务,灵活应对业务变化并快速实现业务需求,并且IT系统对业务的管理、监控、治理提供支持,从而加强了IT系统和业务的一致性。系统由松耦合的业务服务组成,它们依赖于标准的服务接口或者服务描述,但是这些服务接口是离散的。企业内部如果存在大量离散的、分布式的服务接口,并且这些服务接口没有得到有效的管理,IT人员和业务人员需要耗费精力与特定服务接口建立点到点连接,服务接口内部依赖关系也不能够得到展示,从而阻碍了服务的重用。因此,在企业应用集成中的服务管理问题越来越凸显,这正是本课题研究的重点所在。本文在统一描述、发现和集成UDDI3.0协议规范基础上,克服其安全性及消息可靠传递等方面不足,提出一种比较完善的Web服务管理机制,即统一资源管理Global Repository,GLR。通过一个企业级的服务元数据库与资源存储库,建立统一的Web服务管理机制,用于存储、查找、发布、订阅以及管理企业服务与资源。基于GLR,可以对企业服务与资源进行统一管理,并形成一个全局的服务与资源视图,同时促进企业服务与资源的复用。GLR主要通过促进服务与资源重用、优化服务与资源使用、服务与资源的可视化三个方面保证SOA对业务敏捷性的承诺。统一的服务管理机制促进企业服务和资源重用、优化资源使用,避免重复开发,有利于降低企业成本;支持服务和资源在整个生命周期中的管理;并可使用其他标准服务注册中心和存储库,确保跨多个资源。本文以企业供应链系统中订单管理系统和生产管理系统的整合为例,借助于融合ESB、BPM和GLR等技术的SOA应用集成方案解决这个问题。使用企业服务总线实现对原有服务的路由、封装,使用业务流程管理对整个供应链的业务过程进行编排,从而使整个业务过程通过业务流程集成起来,并且可将该业务流程发布为Web服务作为该业务的入口。重点凸显使用GLR实现对现有服务的注册、管理,系统可以快速调整适应业务变化,充分体现了SOA松耦合,随需应变的特点,充分体现了GLR在企业应用集成中对于服务管理的优势。
[Abstract]:With the continuous development of enterprise SOA applications, IT systems must be able to meet the needs of business change. SOA from the business perspective to guide the construction of enterprise IT systems, more easy to understand the business, flexible response to business changes and quickly realize business requirements. And IT systems provide support for business management, monitoring, and governance, thus enhancing the consistency between IT systems and business. Systems consist of loosely coupled business services that rely on standard service interfaces or service descriptions. But these service interfaces are discrete. If there are a large number of discrete, distributed service interfaces within the enterprise, And these service interfaces are not effectively managed by IT and business people who require effort to establish point-to-point connections with specific service interfaces, and dependencies within service interfaces cannot be demonstrated. Therefore, the problem of service management in enterprise application integration becomes more and more prominent, which is the focus of this research. This paper is based on the unified description, discovery and integration of UDDI3.0 protocol specification. To overcome its shortcomings in security and reliable message delivery, a relatively perfect Web service management mechanism is proposed, I. E. unified resource management (Global Repository), which is based on an enterprise-level service meta-database and resource repository. A unified Web service management mechanism is established to store, find, publish, subscribe and manage enterprise services and resources. Based on GLR-based, enterprise services and resources can be managed uniformly, and a global view of services and resources can be formed. At the same time, it promotes the reuse of enterprise services and resources. GLR optimizes the use of services and resources by promoting the reuse of services and resources. The visualization of services and resources ensures the commitment of SOA to business agility. A unified service management mechanism promotes enterprise service and resource reuse, optimizes the use of resources, avoids repeated development, and is conducive to reducing enterprise costs. To support the management of services and resources throughout the life cycle, and to use other standard service registries and repositories to ensure multiple resources. This paper takes the integration of order management system and production management system in enterprise supply chain system as an example. With the help of the SOA application integration scheme which integrates ESBP BPM and GLR technology, the enterprise service bus is used to route, encapsulate and orchestrate the business process of the whole supply chain. So that the whole business process can be integrated through the business process, and the business process can be published as a Web service as the entry point of the business. The system can adjust quickly to the changes of business, fully reflect the characteristics of loose coupling and on demand of SOA, and fully reflect the advantages of GLR in service management in enterprise application integration.
