Embodiment Construction

[0022] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0023] In order to support the execution of the BPMN process, it is necessary to overcome its fundamental characteristic of graph-oriented (Graph Oriented). Unlike other executable service composition languages ​​(such as BPEL), the BPMN model only stays at the graphic level for the description of the BPMN process. In fact, the persistence file conforming to the BPMN schema (BPMNSchema) does not clearly indicate the sequence of process execution. Therefore, it is necessary to analyze the directed graph corresponding to the BPMN process to obtain the order in which each node in the graph is executed during the process execution process, and at the same time complete the behavioral semantic operation defined in the BPMN specification when the node is executed. Execution of the entire BPMN model.

Abstract

The invention provides an execution method of BPMN composition service and an execution device thereof. The execution method includes steps of receiving a query message of executing BPMN composition service to construct runtime objects of BPMN according to the query message, analyzing the runtime objects of the BPMN to acquire execution sequence information of streamed objects in the runtime objects of the BPMN, calling an execution method corresponding to types of the to-be-executed streamed objects, and then sequentially executing the steamed objects according to the execution sequence information. By analyzing the streamed objects and the sequence flow in a BPMN graphical model to acquire the execution sequence of the steamed objects and executing relative action according to semantics of flow objects in the BPMN, direct interpretation and execution of the BPMN flow are realized, and semantic compatibility and unity of a business conceptual model, a business process model and a business execution model and execution automation of the BPMN are realized.

Description

technical field [0001] The invention relates to the technical field of BPMN composite services, in particular to an execution method and an execution device of BPMN composite services. Background technique [0002] With the rapid development of Internet technology, service-oriented architecture (abbreviation: SOA) and other networked service software models have been widely used, especially Web services as the best practice of SOA, which has greatly promoted the application of SOA in finance, telecommunications and The development of e-commerce and other fields. In actual business applications, independent World Wide Web services (hereinafter referred to as: Web services) have limited functions, and it is impossible to meet complex business requirements. Some complex business processes involving multiple parties need to integrate existing Web services to form higher-level service combinations. As the core technology to realize flexible cross-organizational application integ...
