Service dynamic process arrangement method based on JBPM (Java business process management)

Abstract

The invention discloses a service dynamic process arrangement method based on JBPM. The service dynamic process arrangement method comprises the following steps: firstly, determining a demand range, obtaining a matching template from a QoS (quality of service) template library, and mining and feeding back the corresponding relation between demand and service and specific parameters required by each service; secondly, processing dynamic programming and establishing dynamic binding between the service and the template through a system according to the specific parameters introduced through feedback; thirdly, arranging a process to generate a process template; fourthly, automatically proceeding the process to generate a process instance; fifthly, changing the process, performing process template rewriting on changed contents utilizing a migration algorithm, so as to generate a new process; sixthly, starting a new process instance, and finishing the process; seventhly, combing data in a result page with data saved by the former process. Through the adoption of the service dynamic process arrangement method based on JBPM, a series of works are accomplished by the system according to requirements of a user, the process template is automatically generated for accomplishing core operation, required service can be dynamically changed during processing, and the accuracy and efficiency of the process are guaranteed through the migration algorithm.

Description

[0001] technical field [0002] The invention relates to the field of service computing, in particular to a JBPM-based service dynamic flow arrangement method. Background technique [0003] With the rapid development of computer technology, the application of the Internet is becoming more and more popular, and the business needs in the large-scale cross-organizational network environment are more dynamic and changeable. The key to realize the dynamic integration of the system is to realize transparent access to resources, dynamic process reorganization and automatic migration. . [0004] The traditional component-oriented technology can create reusable software component modules, and solve the relatively fixed business model process arrangement through component assembly, which has high efficiency. Because component-oriented technology mainly focuses on creating reusable components of specific systems Modules, with limited scalability, cannot well support the dynamic re...

Problems solved by technology

[0006] Aiming at the characteristics of dynamic change and rapid growth of service orchestration, the programmability and flexibility of the current workflow model are still relatively limited. The research on process migration only realizes partial migration under the condition that the structure of the process definition file remains unchanged, and requires Manually modify the process definition file and specify the migration target

It cannot provide support for automatic migration caused by operations such as node name changes and node deletions in the process. The migration strategy adopted for processes with no structural changes in definition files is relatively simple, but this process will generate a large number of redundant nodes. Repeated execution, reduces the efficiency of the system

Most of the orchestration of the process only studies the problem of realizing the predictable process orchestration
