| Abstract: | 現今的應用系統中常會有橫跨性(Cross-Cutting)的程式模組存在，這類程式模組包括：日誌記錄、授權認證、資料永存性等，而這種程式模組在系統中若沒有被區分抽離出來，常常會導致系統重複出現與主要功能需求無關的程式碼，除此之外，這些橫跨性需求的程式碼還會與主要功能需求程式碼糾結在一起，造成程式碼夾雜不清的現象。在工作流程(Workflow)的開發過程中也有著相同的問題。為了解決上述的問題，本研究以JBoss jBPM(Java Business Process Manage- ment)為基礎平台，將剖面導向程式設計(Aspect-Oriented Progra- mming)的觀念與技術運用在工作流程的領域中，使流程設計人員能夠利用AOP的方式來解決橫跨性需求的模組化問題，並且利用靜態織入方法，改善jBPM工作流程引擎進行剖面流程在織入時的效能。
Cross-cutting concerns are those system design issues that cut across the various modules of an application and are typically foundational system services that we need to consider before diving into building an application. Most common among these are logging, authentication, authorization, and persistence. Cross-cutting concerns always cause program code to be scattered and tangled, and therefore make it harder to understand and maintain. Similar problem also occurs in the field of workflow. In our research, we apply the concept of aspect-oriented programming(AOP) to the field of workflow system, and implement a static weaver for jBPM. With static weaver, process designer can use the facilities of AOP, and the performance is also improved via static weaving .
