| As nowadays more and more efforts are made to informatise enterprises and public institutions, the demands for business capability, operating efficiency and development efficiency etc of OA systems, ERP systems and other systems are growing. Technically, with world-wide application of Java, various excellent frameworks and modules have been developed for Java, which gradually improve coding efficiency, provide more powerful business capability and hence allow more and more systems developed on the basis of this computing language. In the area of workflow, several frameworks, e.g. OpenWHE, jBPM, Activiti and Shark, have been developed using Java and some homemade workflow engines even arose in Chinese domestic market. Such frameworks provide strong support and guarantee for us to construct an excellent, robust and efficient system. Meanwhile, a series problems, such as unstable underlying architecture, low operating efficiency, inflexibility and hardness to adjust, are in need to be further resolved and improved.This thesis applies the Java Web open-source framework and SSH framework(Struts, Hibernate, Spring) prevalent currently to develop a practical system and build a system of office automation based on Web so that it can meet the demand of daily office work of some municipal establishment management office. Based on this, by adopting the comparatively prevalent Java workflow framework and on the basis of the latest Activiti5 workflow development framework, this thesis achieves a set of Web-based government establishment management system with customized workflow, and equips it with functions of backward, customized template and free flow, which involves the analysis of Activiti5 framework source code, integration of frameworks including SSH, Activiti5 and Mybatis, and improvement of the function of Activiti5 workflow framework. In the system completed ultimately, the function of workflow becomes more complete and flexible, and can better serve the entire management system. |
