Abstract

The invention discloses an ECA (Event-Condition-Action) rule based service combination method. The ECA rule based service combination method comprises the following steps of step 1, storing the basic service information corresponding to the external service in the format of XML (Extensive Markup Language) and registering the external service; step 2, storing an ECA rule in format of XML and establishing a mapping table from an event name to the corresponding ECA rule; step 3, performing resolution on request parameters and establishing an event object after a client request arrives, sending the event object to an event channel and forming a first-in first-out message queue; step 4, performing obtaining, resolution and execution on the event object from the event channel through an event engine. According to the ECA rule based service combination method, the dynamic combination that the service is driven by an event can be implemented; only the ECA rule needs to be modified dynamically to implement the update of the service functions when the external service logic is changed; a new event can be triggered according to the activity operation condition through the activity process bound by the ECA rule in the execution process for nested calling or exception notification and accordingly the activeness of the service is improved.

Description

technical field [0001] The invention belongs to the technical field of heterogeneous data fusion and business integration, and more specifically relates to a service combination method based on ECA rules. Background technique [0002] With the continuous change and expansion of business needs of enterprises, how to effectively integrate business resources among various enterprises and various departments of enterprises to meet the functional needs of users' diversity has become an increasingly important issue. In this environment, Web services came into being. Based on a series of underlying standards, Web services provide public services to users through mechanisms such as registration, publishing, and discovery. The service-oriented architecture (Service Oriented Architecture, SOA) can effectively shield the heterogeneous underlying environment in the distributed computing environment, and build service-oriented, loosely coupled, and flexible enterprise applications. Ther...
