Design And Implementation Of Income Verification System Based On J2ee

With the development of Internet technology, information systems have gradually migrated from C/S mode to B/S mode. As for the complicated and changeable market demand, the reliability, stability, scalability and maintainability have become more and more hot spot of the system.In connection with the above-mentioned problems, this thesis, combining the most mainstream framework integrated technologies nowadays, analyze the struts, spring, and hibernate framework in depth. Struts are a MVC-based framework which is divided into three parts which are model, view and controller. Struts will separate the business data, page display and action treatment which is conducive to the maintenance of the various parts and optimizes the structure of the system effectively. Spring framework is mainly responsible for the business layer of the system, the business logic of the application program and transaction management, meanwhile, it is also responsible for carrying out the necessary data checking and binding the direct interaction between the data management and data persistence session layer. Hibernate is one of the Java-based ORM tools which is open source and easy to configure. It communicates directly with the database, carrying out the read and write operation to the database, greatly reducing the workload of compiling sql sentences and packing object.In this thesis, the main work and innovation are as follows:Firstly, the thesis analyzes the technical characteristics of the above framework, Combining with the business requirement of the system, the thesis designs the technique routing of the system.Secondly, the thesis introduces the gross structure of the income checking system, including the MB application system and the income checking application system, and the technical architecture of the system combining with the ssh framework,and then it introduces the functions of each module.Thirdly, the thesis introduces the work flow of the checked economic conditions of the residents as well as the function modules of the dynamic configure, including dynamic query, statistics and dynamic work flow configure as well as the design for the tabular which involved in these function modules.Fourthly, this thesis describes the realization of the work flow of the checked economic conditions of the residents and the dynamic configure,including the realization of the dynamic query and the dynamic configure of the business work flow.The features of this thesis are dynamic configure of the business work flow is to be designed as a result of the different business needed to be expanded in the future and different business has different work flow. This design can make users control the circulation of the business work flow through the visual dynamic of the work flow.Finally, the thesis tests the system on its function and performance through building a test platform. The system adjustment sql statement and the design of the tables for the performance bottle-neck of data base to assure data integrity and safety. At the same time we assess the performance of the system tuning by testing and refining a variety of technical solutions and choose the most optimal configuration in order to improve network response time and system's overall response to the request,thus ensuring the stability and efficient operation of the system.
