JavaEE网络商城毕业设计.docx

前言 SSH2（struts2+spring+hibernate）框架，是当今最为流行的项目开发框架组合，用于构建灵活、易于扩展的多层Web应用程序，掌握SHH2对于今后的工作就业显得尤为重要。本次项目的要求就是以SSH2框架为依托，开发一个完整的网上商城项目(手机销售网站)，最终要形成一个可以独立运行的系统，并完成相关的文档的建立。一、需求分析1.功能分析1.1功能划分本网站为用户提供狗粮销售服务，用户可通过本网站浏览并购买狗粮。依据功能需求，包括用户控制、商品浏览、商品筛选、购物车、结算与支付等功能。1.2功能描述前台部分l 用户控制：提供用户登录、注册和注销功能，其中非登陆用户只能浏览而不能购买商品。l 商品浏览：展示所有商品信息，并提供分页功能。l 商品筛选：提供商品筛选功能，用户可以依据商品关键字进行商品搜索，也可以按照品牌或者价格区间对商品进行筛选。l 购物车：当登陆用户点击产品的购买按钮时，购物车页面弹出，可以将商品加入到购物车，并可对购物车中的数量进行修改。l 结算与支付：登陆用户点击购物车上的结算按钮，后台将会把购物车中的商品生成订单，并跳转到订单中心，订单中心会显示用户所有的订单详细信息（时间，商品信息，数量，订单号，总金额），此时用户可以选择进行支付或是继续浏览商品。2.性能分析2.1数据精确度本项目是一个网上商城项目，涉及到金钱交易，数据的准确性直接影响买卖双方的利益，因此要求极高的数据精确度。2.2时间特性该网上商城项目包含订单功能，要求订单生成时间准确、存入到数据库中的内容及时且有效。2.3适应性本项目采用SHH2框架进行开发，使用MySQL数据库进行信息存取，以Tomcat作为网页服务器，在页面开发过程中也充分考虑到各种浏览器的兼容性问题，能够提供统一、美观的用户界面，支持跨平台，能满足绝大部分用户的需求。3.开发环境l 开发工具：MyEclipse10+MySQL6.0l 操作系统：Win7l 运行环境：JDK1.6+Tomcat二、页面设计该项目前台部分主要包含以下页面：l showCart.jsp:购物车页面，实现购物车功能l index.jsp: 项目主界面，提供最新的产品信息l Checkout_success.jsp:确认订单界面，展示你的订单的信息l browseBookPaging.jsp:产品列表页面，展示所有狗粮，用户再次页面购买狗粮l menu.jsp:菜单页面，物品的分类l searchbook.jsp:通过此页面展示搜索结果l register.jsp:用户注册页面l Register_success.jsp:用户注册成功页面l login.jsp:用户登录界面l login_success.jsp:用户登录成功界面l searchBook.jsp:查找图书页面l addToCart_success.jsp:添加商品页面三、项目实现1.配置文件a) web.xml struts2org.apache.struts2.dispatcher.FilterDispatcherstruts2/* org.springframework.web.context.ContextLoaderListener b) applicationContext.xmlorg.hibernate.dialect.MySQLDialectorg/easybooks/bookstore/vo/Book.hbm.xmlorg/easybooks/bookstore/vo/Catalog.hbm.xmlorg/easybooks/bookstore/vo/Orderitem.hbm.xmlorg/easybooks/bookstore/vo/Orders.hbm.xmlorg/easybooks/bookstore/vo/User.hbm.xmlc) sturts.xml/register_success.jsp/login_success.jsp/login.jsp/index.jsp/menu.jsp/browseBook.jsp/browseBookPaging.jsp/searchBook_result.jsp/addToCart_success.jsp/showCart.jspshowCart.jsp/checkout_success.jsp/login.jsp部分核心代码BookAction.javapackage org.easybooks.bookstore.action;import java.util.*;import org.easybooks.bookstore.service.ICatalogService;import org.easybooks.bookstore.service.IBookService;import com.opensymphony.xwork2.*;import org.easybooks.bookstore.util.Pager;public class BookAction extends ActionSupportprotected ICatalogService catalogService;protected IBookService bookService;protected Integer catalogid;private Integer currentPage=1;private String bookname;public String browseCatalog() throws ExceptionList catalogs=catalogService.getAllCatalogs();Map request=(Map)ActionContext.getContext().get(request);request.put(catalogs, catalogs);return SUCCESS;public String browseBook() throws ExceptionList books=bookService.getBookbyCatalogid(catalogid);Map request=(Map)ActionContext.getContext().get(request);request.put(books, books);return SUCCESS;public String browseBookPaging() throws Exceptionint totalSize=bookService.getTotalbyCatalog(catalogid);Pager pager=new Pager(currentPage,totalSize);List books=bookService.getBookbyCatalogidPaging(catalogid,currentPage, pager.getPageSize();Map request=(Map)ActionContext.getContext().get(request);request.put(books, books);request.put(pager,pager);/购物车要返回时,需要记住返回的地址Map session=ActionContext.getContext().getSession();request.put(catalogid,catalogid);return SUCCESS;public String searchBook() throws Exception StringBuffer hql=new StringBuffer(from Book b );if(bookname!=null&bookname.length()!=0)hql.append(where b.bookname like %+bookname+%);List books=bookService.getRequiredBookbyHql(hql.toString();Map request=(Map)ActionContext.getContext().get(request);request.put(books,books);return SUCCESS;public Integer getCatalogid()return this.catalogid;public void setCatalogid(Integer catalogid)this.catalogid=catalogid;public ICatalogService getCatalogService()return this.catalogService;public void setCatalogService(ICatalogService catalogService)this.catalogService=catalogService;public IBookService getBookService()return bookService;
