Design And Implementation Of Project Management System Based On Struts2Architecture

The project is in the certain organization, in the limited resource conditions, in the plan time, one-time tasks according to meet certain performance requirements, quality and quantity to complete. It is the sum of a number of related Prj to achieve this goal within a certain time. The project is a limited resource, time limit and the specific target in certain conditions the one-time construction Prj or task. With the development of computer technology and system engineering theory, the means and method of project management has been greatly improved, and the application effect is obvious, the use of project management software project management is very necessary. This paper uses Struts2technology, combined with the specific needs of telecommunication construction project management, communication engineering project management system with the characteristics of the telecommunications industry analysis, design and implementation.Firstly, a detailed description of the telecommunication construction project management business process, described in detail from the project process, planning process, design process, construction process, bidding process, engineering settlement process in6main aspects, on the basis of describing system construction goal.The paper then designs engineering project management system of general logic structure and function structure, using UML modeling language, carries on the detailed design to the database, the database and database class diagram of the system are given, database table structure design.The paper then deeply analyses the system structure of Struts2and the development and runtime environment configuration, description of the object graph navigation language, presents a detailed implementation method in strust2interceptor, custom interceptor is given, using interceptor implementation example authority verification, finally the paper designs the system main interface prototype.This paper from the implementation of the project examination and approval, bidding management, project construction and project acceptance of the whole process of telecommunication engineering project management system, to ensure the project in accordance with the schedule, quality requirements of the contract and quantity, improve the project management level, and achieved good application effect.
