Based On SSH2 Dynamic Workflow Model Research And Application

Workflow technology is through workflow routing management of enterprise business, However, because of the rapidly changing market environment, enterprises need to constantly improve their business process.Then request workflow model can also auto-adapted and dynamically to changing business needs support,be able to dynamically modify the task defined by the business process workflow process, So as to achieve task flow a high degree of flexibility and orderly effective management.The main topic of the work of the first analysis of WfMC(Workflow Management Coalition)workflow management system architecture and dynamic workflow technique and its applications, and the application as well as the SSH2-MVC design pattern theory, Based on the above these basic theory. Design and implementation of Web services flexible, easy extension of SSH2(Struts2SpringHibernate)dynamic workflow model. Second, This paper summarizes the main SSH2 dynamic workflow model function modules and implementation mechanism. In this model the main research and implementation of three aspects of work. Firstly, task flow control; May adapt to a dynamic modification task flow process. The main implementation mechanism is process definition file assigned tasks timely treatment level degrees. The model will dynamically based on it the implementation process of modified task flow. Secondly, Flow example exception handling; The model adapts to carries out the flow example exception handling. The main implementation mechanism is the use of unusual activity to find node in the normal process of the implementation of the recent activities of the task nodes. At the same time start the compensation mechanism for active nodes. So as to achieve the purpose of process instances anomalies. The process instance to complete the implementation of the node in the unusual activity and be able to submit it to the next active node. Third; Regarding flow duty related parameter processing; The main implementation mechanism defined in the process into the dynamic form, The model were respectively from the form of data types, input form as well as dynamic form of independent parameters stored in different aspects of the design and implementation.Finally; SSH2 dynamic workflow model has carried on the performance test. Mainly reflected in the operating cycle of the process and process aspects of the average throughput session. According to the test results show that this model can be adapted to workflow technology in the enterprise to changing business needs.
