Embodiment Construction

[0042] In order to enable those skilled in the art to better understand the solutions of the embodiments of the present invention, the embodiments of the present invention will be further described in detail below in conjunction with the drawings and implementations.

[0043] First, refer to figure 1 It is a rule engine-based service dynamic composition architecture diagram of the method of the present invention, including: a service calling agent, a service converter, a business rule library, a rule engine and a rule management interface.

[0044] refer to figure 2 It is a flowchart of a rule-based service dynamic composition method in an embodiment of the present invention, and business rules are added to a rule base in the form of rules. And register all replaceable service pair information and mapping relationship in the service information center. The service addresses in the Web service nodes in all WSDL descriptions in BPEL are replaced with the service call proxy ad...

Abstract

The invention discloses a method and system for dynamically combining services based on a rule engine. The method comprises the following steps of: intercepting web service calling request information and service response return information; distributing a unique identifier for the intercepted service calling request information and interpolating the request information into the rule engine; interpolating the intercepted service response return information into the rule engine; reasoning a service processing strategy of a service according to a service rule and context data needed by rule execution; and replacing the service calling information and re-orientating the service according to a service replacing scheme reasoned by the rule engine and service transition mapping information provided by a service information center. By adopting the method and the system, the flexibility and the sensitivity of the system in the aspects of development and maintenance of a new flow and modification of an old system service rule can be enhanced.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a rule engine-based service dynamic combination method and system. Background technique [0002] As an important means of service composition, BPEL is a modeling and description language for business processes. BPEL declares the provided service interface and dependent service interface and data interface through WSDL, and specifies the calling sequence of services through BPEL's basic activities and process activities. Web services are performed in order, selection, cycle, and concurrency. However, in actual application, there are two problems that often plague BPEL developers and maintainers, that is, the scalability and flexibility of service composition. [0003] On the one hand, BPEL is quite cumbersome when faced with large-scale Web service composition, and lacks good scalability. There are often a large number of Web services in banking, telecommunications, tourism an...
