【摘要】：如今的BOSS系统正面临业务快速变更的发展需求,众多公司纷纷使用面向服务的架构(SOA)来构造系统。使用SOA构建的业务系统具有可装配性,因此,如何将业务细化成精准的服务就成了重中之重。目前的理论方法都仅仅提供了简要说明,并未对理论的应用效果做出阐述。本文通过描述如何对BOSS系统实施SOA过程来确定服务发现方法的步骤和关键因素,同时以一个实际的项目作为背景,对其业务构造出的服务进行深入分析和探究。论文的主要工作如下:首先,选取了一种服务建模方法论—面向服务的建模与体系结构(SOMA),并对其进行性能预测。该方法论主要负责在进行SOA实施时提供服务识别工作的方法,并指导开发人员对识别出的服务结果进行规范和实现。以一个业务流程为例,对方法论的理论内容的逐个方法应用以预测其在整个BOSS系统中的性能。其次,使用SOMA方法论对BOSS系统进行服务发现。本文以BOSS系统的一个业务场景为例,分别使用SOMA方法论中的三种服务发现方法对BOSS系统进行服务发现。同时,根据对BOSS系统的全部业务流程进行服务发现得到的结果,进行对SOMA方法论三种方法的性能分析,确定了各个方法所发现服务的特征。最后,根据SOMA方法论的应用结果进行了业务流程模拟。本文根据使用SOMA方法论得到的服务集合和流程,应用WS02软件进行了多角色的流程模拟。该模拟整合了服务重用、服务组装等多个SOA中流程性服务所要求的特性,验证了 SOMA的正确性和可行性。
[Abstract]:Nowadays, BOSS system is facing the development demand of rapid change of business. Many companies use service-oriented architecture (SOA) to construct the system. The business system built with SOA has the ability to assemble, so how to refine the business into precise service becomes the most important. At present, the theory and methods only provide a brief explanation, not the application of the theory. This paper describes how to implement the SOA process in BOSS system to determine the steps and key factors of the service discovery method. At the same time, taking a practical project as the background, the paper makes a deep analysis and exploration of the service constructed by the service. The main work of this paper is as follows: firstly, a service modeling methodology, service-oriented modeling and architecture (SOMA), is selected and its performance is predicted. This methodology is mainly responsible for providing methods for service identification in SOA implementation and instructing developers to standardize and implement the identified service results. Taking a business process as an example, the theoretical content of methodology is applied one by one to predict its performance in the whole BOSS system. Secondly, the service discovery of BOSS system is carried out with SOMA methodology. Taking a business scenario of BOSS system as an example, this paper uses three service discovery methods in SOMA methodology to realize service discovery in BOSS system. At the same time, according to the results of service discovery of all business processes in BOSS system, the performance analysis of three methods of SOMA methodology is carried out, and the characteristics of the services found by each method are determined. Finally, the business process simulation is carried out according to the application result of SOMA methodology. According to the service set and process obtained by using SOMA methodology, this paper uses WS02 software to simulate the multi-role process. The simulation integrates the characteristics of service reuse, service assembly and so on, and verifies the correctness and feasibility of SOMA.
