The Implement Of The Order Management System Based On The Struts Frame

This article is a party of storage management system, belongs tothe cargo order management module. It mainly has realized the ordersearching and retrieving the result on the further operation.Firstly, it simply introduces the Web technology brief history, inwhich explains deficiency early time GUI in use, that is each requestmust start a new thread, this causes possibly to have such situation,which is if the GUI procedure itself is execution in a short time, the startthread needs expense a lot of time that surpass the actual executiontime, and GUI has not considered to the multithreading processingand the realization.So it introduces Servlet based on theseshortcomings of GUI, the Servlet procedure in the server end movement,dynamically produces the Web page. Comparing with traditional GUIand many other similar GUI technology, it has a higher efficiency, iseasier to use, the function is more formidable, has a better probability,saves the investment,And has realized the multithreading. The Servletshortcoming is that you need to put together HTML strings manually,which the Servlet realizes and makes static state HTML moreconvenient in JSP.More importantly, with the aid of the content and theoutward appearance separation, in the page manufacture theheterogeneity duty may be conveniently separate. And simplyintroduced framework, it has multilayered software development projectand is favorite by more and more the people.In view of the fact that this article is base on MVC structure andstruts frame, the article also the system introduced uses widely of theMVC structure, shows three layers content and the function, as well asthe advantage of three layers structures, avoids having the user to visitthe database directly . At the same time, also causes the entire projectdivided to be clear about, each part has development personnel . Thedevelopment personnel only needs more energy on an own part, butdoes not have to finish others, which causes the overall system clearly .At the same time, unifies the MVC structure, in more detailedintroduction project base on the struts frame from aspects and strutsmain system structure and principle of work, explains how the framerealizes the MVC structure.Fourth chapter and the fifth chapter are this article core parts. Thefirst, the simple introduction entire project warehouse cargomanagement system ,and introduces with emphasis regarding thecargo the order form management party. This module is called orderingmanagement. The MVC pattern and the struts frame are used to showin this module, how application these technologies. And how thetechnologies are in the control level has applied, how to realize. In theview level, the application technology is ActionForm which strutsprovides the Bean module, uses in receiving the onstage the data, theonstage page realization, has used JSP, has used JavaScrip for thebutton control, the function of dividing the page is tag which the peoplemade by himself in this system. To prompt news more usefully itinturoduced to the Validator frame. This frame relies on two JARdocument, They are placed in WEB-INF document and provided agroup of function and so on division. With the Validator fame it is simple,is easy to be expanded ,contains a lot of the confirmation metheods andthe confirmation rules ,The project uses the confirmation frame andexpands the frame to realize union verification. Partially, the functionsare introduced in the fifth chapter on detail. All operation use java torealize . In retrieval function realized the multi-tables union inquiry, themodule initial period expression but also has the deletion which unifiedwith the retrieval function, about the PDF operation including open andpreserves, when uniting this module with other modules time, neededto use to the data mutual transmission and the data preservation. At thesame time, question description which meets in the practical application,and how solves the question explanation, and,considered has all usedthe retrieval function to very many modules, in order to realizeeffectiveness and the stability. Simply the article introduced the systemexception handling part. The test also is important part in the softwaredevelopment, in this part, has mainly tested for the system stability,,page friendliness, whether realizing the function which requests,whether the result are the expectation.
