The Design And Implementation Of Logistics Management System Based On JBPM And J2EE

With the rapid development of China's economy,the increase in resident income and the rise of e-commerce in recent years,logistics industry has ushered in an era of rapid development.However,the low informationization and intellectualization of China's logistics industry is still out of keeping with the explosive growth of logistics traffic.Some small and middle-sized logistics enterprises are just managed in a manual way,while some merely have a backward information management system.Due to the poor security and scalability,they cannot meet the requirements of mass transport,inter-regional transfer and rapid transportation,but have to suffer from more and more defects in dispatch,warehousing and distribution.This topic is derived from an actual project,aimed at building a convenient and efficient logistics management system to realize the informationization and intellectualization of logistics industry management.In accordance with the business requirements of China's logistics information system,this paper built a logistics management information system based on the comprehensive use of SSH framework,JBPM workflow engine,Dubbo framework,Lucene full-text retrieval technology and SSL security protocol.The main work of this paper is shown as follows:(1)According to a field investigation and discussion of transfer distribution,this paper summarized and analyzed the aggregate demand of logistics management information system.The system consists primarily of basic business platform and JBPM workflow platform.Based on the traditional MVC design pattern,the intermediate layer was expanded into a business logic layer and flow logic layer,to facilitate system development,maintenance and expansion.(2)An overall system proposal was designed according to the functional requirements and performance requirements of the system.The functional design of the system consists of basic data module,operational acceptance module,logistics distribution module,transfer distribution module and system management module.EasyUI and Ztreeare used to realize the display of the system interface layout and data;Hibernate and Lucene technology are used to realize the conditional retrieval and management of the data.Operation areas are subdivided and modeled in operational acceptance and distribution modules,to complete intellectualized order placing,dividing and dispatching operations.JBPM flow engine is used to define,publish and monitor flow in transfer module to realize efficient and intelligent management over logistics distribution process.Authority management is realized in the system based on Struts interceptor by designing a JBPM authority model and Ztree dynamic menu.JBPM workflow technology is adopted and integrated with SSH framework in flow logic layer,which is solely responsible for the circulation and control of operation flow for a reduction in the coupling degree of the system.Simultaneous use is made of Spring framework to integrate Dubbo framework to realize distributed service registration and control of the system,and SSL security protocol is used to enhance the security of the system.(3)Various system function modules,such as data module,acceptance module,distribution module and transfer distribution module,were developed and implemented according to the detailed design of this system.An optimization scheme was designed for security architecture.Namely,a key acceleration server was used to speed up SSL handshake flow to improve the communication speed of this system.
