高速公路拌合站管理系統(tǒng)的設(shè)計(jì)與實(shí)現(xiàn)(完整版)
【正文】 了堅(jiān)實(shí)的基礎(chǔ)，同時，開發(fā)網(wǎng)站的成熟工具也非常多，比如， Visual Studio、 Delphi、 Eclipse、 NetBeans 等。在保證先進(jìn)技術(shù)的基礎(chǔ)上，深入廣泛的了解了行業(yè)用戶的需求，形成獨(dú)特的行業(yè)特色。 第 3章 過程論述 整個項(xiàng)目是基于 B/S模式，應(yīng)用 Struts Spring Hibernate 三個框架實(shí)現(xiàn)了一個整個拌和站管理系統(tǒng)。 IC 卡稱重，也可以不使用 IC 卡稱重。完成后課程設(shè)計(jì)，我也認(rèn)識到了自己的不足之處，學(xué)過的知識掌握的不扎實(shí)，新的知識不能很好地理解，在以后的設(shè) 計(jì)中一定要避免這次發(fā)生的問題，在規(guī)定的時間高質(zhì)量的完成項(xiàng)目設(shè)計(jì) 。 Action接口不是必須的，任何有 execute 標(biāo)識的 POJO對象都可以用作 Struts2的 Action對象。 Action 屬性能夠通過 web 頁面上的 taglibs 訪問。提供基本和常用對象的轉(zhuǎn)換器。 目的：解決企業(yè)應(yīng)用開發(fā)的復(fù)雜性。它帶來了很多自動化和代碼節(jié)省方面的好處，所以花一點(diǎn)時間學(xué)習(xí)它是值得的。我 所在 的公司就曾有過在開發(fā)過程后期被迫更換數(shù)據(jù)庫廠商的經(jīng)歷。 范圍：任何 Java應(yīng)用。堆棧能夠根據(jù)需要和不同的 Action一起使用。 rich對象類型，包括業(yè)務(wù)對象，能夠用作輸入 /輸出對象。實(shí)際上， servlet 容器給每個請求產(chǎn)生 許多可丟棄的對象，并且不會導(dǎo)致性能和垃圾回收問題 。s ancestry, but the succession WebWork lineage. Struts2 is the WebWork upgrade, rather than an entirely new framework, therefore the stability, performance and other areas have a very good assurance: it absorbed the advantages of both Struts1 and WebWork, therefore, is a very worth the wait framework. Struts2 Action class can implement an Action interface and other interfaces can also be achieved to enable optional and custom services possible. Struts2 provides a ActionSupport to achieve mon base class interface. Action interface is not necessary, any POJO object execute identity can be used as an object Struts2 in Action. Struts2 Action object for each instance of a request to generate a, there is no threadsafety problems. (In fact, servlet containers generate many for each request can be discarded objects, and will not lead to performance and garbage collection issues). Struts2 Action does not depend on the container, allowing Action out of the container to be tested separately. If necessary, Struts2 Action can still access the original Request and Response, however, other elements to reduce or eliminate direct access to HttpServetRequest and HttpServletResponse necessary. Struts2 Action can be initialized, set properties, call methods to test, dependency injection support also makes testing easier. Struts2 using the Action attribute directly as input properties, eliminating the need for the second input object needs. Input properties may have their own (sub) attribute the rich object type. Action properties able to access web pages on the taglibs. Struts2 also supports the ActionForm pattern. rich object types, including business objects, can be used as input / output objects. This ModelDriven feature simplifies the taglib reference to the POJO input objects. Struts2 can use JSTL, but also supports a more powerful and flexible expression language Object Graph Notation Language (OGNL). Struts2 using the ValueStack technology, so that the value of taglib to access your pages without the need to (view) and object to bind together. 2. Spring Introduction Spring is an opensource framework, created by Rod Johnson. It is the development of enterprise applications in order to solve the hybrid nature of hair created. Spring using the basic JavaBean to plete before the EJB is only possible to plete things. However, Spring is not limited to the use of serverside development. From the simplicity, testability, and loose coupling point of view, any Java application can benefit from the Spring. Objective: To solve the plexity of enterprise application development. Function: Using the ba
