购物车网站的自定义框架实现

首先要收一下这个自定义框架，是别人实现的，适合初学者使用，仿照Struts的框架原理，将servlet的访问通过类反射全部封装了，不需要向上一个图书管理项目那样写servlet了，框架就是源码里org包下的内容，完全可以打成jar文件使用，这里我提供了源文件，框架的功能很强大，有需要的自己去下载学习啦

所以的环境同上一个图书管理项目一样，支持自动建表

框架的使用可以参考视频：http://v.youku.com/v_show/id_XMTQzMjc4Njk5Ng==.html

框架的讲解可以参考视频：http://v.youku.com/v_show/id_XMTQzMjc4NjA3Mg==.html

单独的框架：http://download.csdn.net/detail/i_do_can/9386767

购物车项目：

需求分析：



在使用框架之前，需要配置几个地方，本项目使用proxool连接池。配置连接池XML文件

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE proxool>

<proxool>
<alias>shop_nxf</alias> <!--数据源的别名 -->
<driver-url>jdbc:mysql://localhost/shop_nxf?characterEncoding=UTF8</driver-url><!--url连接串 -->
<driver-class>com.mysql.jdbc.Driver</driver-class> <!--驱动类 -->
<driver-properties>
<property name="user" value="root" /> <!--用户名 -->
<property name="password" value="" /><!--密码 -->
</driver-properties>
<maximum-connection-count>100</maximum-connection-count>
<minimum-connection-count>10</minimum-connection-count>
<house-keeping-sleep-time>90000</house-keeping-sleep-time>
<maximum-new-connections>10</maximum-new-connections>
<prototype-count>5</prototype-count>
<test-before-use>true</test-before-use>
<house-keeping-test-sql>select 1</house-keeping-test-sql>
</proxool>

使用框架也是需要配XML 文件的 appconfig.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE app-config>

<app-config>
<!-- action包 -->
<package>com.cl.homework.action</package>
<!-- 后缀 -->
<suffix>Action</suffix>
<!-- 别名 -->
<!-- proxool.xml 中定义 -->
<alials>proxool.shop_nxf</alials>
<pagesize>5</pagesize>
<pagefull>full</pagefull>
<ddlauto>create</ddlauto>

</app-config>

这里的参数参考：appconfig.dtd

<!ELEMENT app-config (package,suffix?,parameter?,alials?,pagesize?,pagefull?,ddlauto?,driver?,url?,user?,password?)>
<!ELEMENT package   (#PCDATA)>
<!ELEMENT suffix    (#PCDATA)>
<!ELEMENT parameter (#PCDATA)>
<!ELEMENT alials 	  (#PCDATA)>
<!ELEMENT pagesize  (#PCDATA)>
<!ELEMENT pagefull  (#PCDATA)>
<!ELEMENT ddlauto   (#PCDATA)>
<!ELEMENT driver    (#PCDATA)>
<!ELEMENT url       (#PCDATA)>
<!ELEMENT user      (#PCDATA)>
<!ELEMENT password  (#PCDATA)>

再就是配置web.xml文件了,过滤器也是框架提供好的

<servlet>
<servlet-name>ServletConfigurator</servlet-name>
<servlet-class>org.logicalcobwebs.proxool.configuration.ServletConfigurator</servlet-class>
<init-param>
<param-name>xmlFile</param-name>
<param-value>WEB-INF/proxool.xml</param-value>
</init-param>
<load-on-startup>0</load-on-startup>
</servlet>
<pre name="code" class="java"><!-- 自定义框架-->

<servlet> <servlet-name>RoadMap</servlet-name> <servlet-class>org.nxf.frame.RoadMap</servlet-class> <init-param> <param-name>xmlFile</param-name> <param-value>appconfig.xml</param-value> </init-param> <load-on-startup>0</load-on-startup>
</servlet> <servlet-mapping> <servlet-name>RoadMap</servlet-name> <url-pattern>*.do</url-pattern> </servlet-mapping> <!-- 中文过滤器 --> <filter> <filter-name>EncodingFilter</filter-name> <filter-class>org.nxf.frame.util.EncodeFilter</filter-class> <init-param>
<param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> </filter> <filter-mapping> <filter-name>EncodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>

配置晚这些就可以新建包啦，看看包结构



不知是否还记得上一篇说的三层结构，这里使用了框架，这三层也是不能少的 ，框架把数据库的连接以及CRUD，servlet层都做好了

bean是存放实体类的，dao 和 service是由于后面需要多表操作

下面分模块对这个项目进行讲解：

1.商品显示模块-分页显示所有的商品

ProductAction：

public ProductAction() {
//父类提供的方法     表名，类名
this.setService(new Service("tbl_product","com.cl.homework.bean.Product"));
//jsp文件的地方
this.setDir("product");
}

public void PageQueryProduct(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
// TODO Auto-generated method stub
page(request, response);
}

page是框架提供的，框架功能很强大，但是有一些小问题，我也是边用边修改的

public void page(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
String strp = request.getParameter("p");
String name = request.getParameter("name");

int p = 1;
if(strp!=null){
p = Integer.parseInt(strp);
}
Pages pages =Pages.getInstance();
if (service != null) {

pages.setCurrentPage(p);

pages.setUrl(ContextConfig.redirect+"?"+ContextConfig.parameter+"=page");

if(name != null){
//通过名字查询
list = service.getPage(name,(p-1)*pages.getPageSize());
pages.setTotalRow(service.getRecordTotal(name));
}else{
pages.setTotalRow(service.getRecordTotal());
list = service.getPage((p-1)*pages.getPageSize());
}

String strPage = "";
if(ContextConfig.pagefull.equals("full")){
strPage = pages.getLoopPage();
}else{
strPage = pages.getPageStr();
}
request.setAttribute("list", list);
request.setAttribute("pageText",strPage);
}
if (dir != null){
request.getRequestDispatcher(dir + "/list.jsp").forward(request,response);
}
}

jsp页面：

<c:forEach items="${list}" var="p" varStatus="vs">
<tr>
<td class=tablebody2 valign=middle align=center>${vs.count }</td>
<td class=tablebody1 valign=middle align="center">
<a href="product.do?a=ViewProduct&productid=${p.productid}">${p.name }</a>
</td>
<td class=tablebody2 valign=middle align=center>${p.baseprice }</td>
<td class=tablebody1 valign=middle align=center>
<a href="product.do?a=AddCart&productid=${p.productid}"><img border="0" src="images/car_new.gif"></a>
</td>
</tr>
</c:forEach>

想要使用分页，页面只要加一个参数就好了

<center>${pageText }</center>

2.商品显示模块-查看单个商品

<span style="white-space:pre">		</span>String id = request.getParameter("productid");
Product p = (Product) service.getOne("productid",Integer.valueOf(id));
request.setAttribute("p", p);
request.getRequestDispatcher("product/viewProduct.jsp").forward(request, response);

<span style="white-space:pre">	</span><table cellpadding=3 cellspacing=1 align=center class=tableborder1>
<tr>
<td valign=middle align=center height=25 background="images/bg2.gif" colspan="2">
<p><font color="white"><b>${p.name }</b></font>
</td>
</tr>
<tr>
<td class=tablebody1 valign=middle align=center width="20%">【作  者 】</td>
<td class=tablebody1 valign=middle width="80%">${p.writer }</td>
</tr>
<tr>
<td class=tablebody1 valign=middle align=center width="20%">【价  格 】</td>
<td class=tablebody1 valign=middle width="80%">${p.baseprice }</td>
</tr>
<tr>
<td class=tablebody1 valign=middle align=center width="">【出 版 社】</td>
<td class=tablebody1 valign=middle width="">${p.publish }</td>
</tr>
<tr>
<td class=tablebody1 valign=middle align=center width="">【 页  数】</td>
<td class=tablebody1 valign=middle width="">${p.pages }</td>
</tr>
<tr>
<td class=tablebody1 align=center width="" valign="top">【 简  介】</td>
<td class=tablebody1 valign=middle width="">${p.description }</td>
</tr>
<tr>
<td class=tablebody1 valign=middle align=center >【 封  面】</td>
<td class=tablebody1 valign=middle width="">  <img border="0" src="${p.images }" width="127" height="180"></td>
</tr>
<tr>
<td class=tablebody2 valign=middle align=center colspan="2">
<a href="product.do?a=AddCart&productid=${p.productid}">
<img border="0" src="images/buycar.gif" width="92" height="21">
</a>
</td>
</tr>
</table>

3.商品显示模块-搜索商品

这个在查看所有商品里已经做好了，我那边传了一个参数过去，name ,商品的名称，

jsp只需要做一个搜索框就好了

<script type="text/javascript">

function search() {
var name = document.getElementById("name").value;
if(name != ""){
location.href = "product.do?a=PageQueryProduct&name=" + name;
}
}
</script>

商品名称：<input type="text" id="name" value="${name}"/>
<input type="button" value="搜索" onclick="search()"/>

4.用户模块-新用户注册，用户修改注册信息：

写个jsp:

<table cellpadding="3" cellspacing="1" align="center" class="tableborder1" id="table1">
<tr>
<td valign="middle" colspan="2" align="center" height="25" background="images/bg2.gif">
<font color="white"><b>用户信息修改</b></font></td>
</tr>
<tr>
<td width="40%" class="tablebody1"><b>用户名</b>：<br>
注册用户名长度限制为0－16字节</td>
<td width="60%" class="tablebody1">
<input maxLength="8" size="32"  name="username" value="${user.username}" readonly="readonly" style="font-family: Tahoma,Verdana,宋体; font-size: 12px; line-height: 15px; color: #000000">
<font color="#FF0000">*</font></td>
</tr>
<tr>
<td width="40%" class="tablebody1"><b>密码(至少6位，至多8位)</b>：<br>
请输入密码，区分大小写。<br>

</tr>
<tr>
<td width="40%" class="tablebody1"><b>密码(至少6位，至多8位)</b>：<br>

</td>
</tr>
<tr>
<td class="tablebody2" valign="middle" colspan="2" align="center">
<input type="submit" value="确定">

</tr>
</table>

UserAction:这里把新增和修改写在一起了，区别就是修改有id而新增没有

public void RigisterUpdateUser(HttpServletRequest request, HttpServletResponse response)
throws IOException, ServletException {

String userid = request.getParameter("userid")==null?"":request.getParameter("userid").trim();
String username = request.getParameter("username")==null?"":request.getParameter("username").trim();
String password = request.getParameter("password")==null?"":request.getParameter("password").trim();
String street1 = request.getParameter("street1")==null?"":request.getParameter("street1").trim();;
String street2 = request.getParameter("street2")==null?"":request.getParameter("street2").trim();
String city = request.getParameter("city")==null?"":request.getParameter("city").trim();
String zip = request.getParameter("zip")==null?"":request.getParameter("zip").trim();
String email = request.getParameter("email")==null?"":request.getParameter("email").trim();
String homephone = request.getParameter("homephone")==null?"":request.getParameter("homephone").trim();
String cellphone = request.getParameter("cellphone")==null?"":request.getParameter("cellphone").trim();
String officephone = request.getParameter("officephone")==null?"":request.getParameter("officephone").trim();
String truename = request.getParameter("truename")==null?"":request.getParameter("truename").trim();
User user = new User();
user.setUsername(username);
user.setStreet1(street1);
user.setStreet2(street2);
user.setCity(city);
user.setZip(zip);
user.setEmail(email);
user.setHomephone(homephone);
user.setCellphone(cellphone);
user.setOfficephone(officephone);
user.setTruename(truename);

HttpSession session = request.getSession();
//注册
if(userid.equals("")) {
user.setPassword(password);
}else {
//修改密码
User sessionUser = (User)session.getAttribute("user");
if(!password.equals(sessionUser.getPassword())) {
user.setPassword(password);
}else {
user.setPassword(password);
}
user.setUserid(Integer.valueOf(userid));
}
service.save(user);
session.setAttribute("user", user);
request.getRequestDispatcher("product.do?a=PageQueryProduct").forward(request, response);

}

5.用户模块-用户登陆：

jsp:

<table cellpadding=3 cellspacing=1 align=center class=tableborder1>
<tr>
<td valign=middle colspan=2 align=center height=25 background="images/bg2.gif" >
<font color="white"><b>输入您的用户名、密码登录</b></font>
</td>
</tr>
<tr>
<td valign=middle class=tablebody1>请输入您的用户名</td>
<td valign=middle class=tablebody1><INPUT name=username type=text>
<a href="register.jsp">没有注册？</a>
<font color="red">${message}</font>
</td>
</tr>
<tr>
<td valign=middle class=tablebody1>请输入您的密码</td>
<td valign=middle class=tablebody1>
<INPUT name=password type=password>
</td>
</tr>
<tr>
<td class=tablebody2 valign=middle colspan=2 align=center>
<input type="submit" value="登 录">
</td>
</tr>
</table>

<span style="white-space:pre">	</span>public void Login(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
String username = request.getParameter("username").trim();
String password = request.getParameter("password").trim();

User user = (User) service.getOneByName(username);

HttpSession session = request.getSession();

//用户名不存在
if(user!=null &&user.getUsername()!=null && password.equals(user.getPassword())) {
//登陆成功，密码是加密后的，去注册修改servlet
session.setAttribute("user", user);
request.getRequestDispatcher("product.do?a=PageQueryProduct").forward(request, response);
}else {
request.setAttribute("message", "用户名或密码不对");
request.getRequestDispatcher("/login.jsp").forward(request, response);
}

}

6.用户模块-用户登出：

登陆的用户是存在session里的，登出就是从session里移除，我这里是因为后面购物车也是放在session里的，所以退出时要把购物车也清空

public void LogOut(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
HttpSession session = request.getSession();

if(session.getAttribute("user")!=null) {
//用户已登陆
session.removeAttribute("user");
session.removeAttribute("cartList");
session.removeAttribute("sum");
request.getRequestDispatcher("product.do?a=PageQueryProduct").forward(request, response);
}else {
//用户未登录
request.setAttribute("message", "请先登陆");
request.getRequestDispatcher("/login.jsp").forward(request, response);
}
}

7.购物车-加入商品到购物车

public void AddCart(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
String productid = request.getParameter("productid");

//查出货品的信息，service是null，所以提供表明，id字段
Product p = (Product) service.getOne("productid",Integer.valueOf(productid));

HttpSession session = request.getSession();
//未登录时，不可以操作购物车
if(session.getAttribute("user")==null) {
request.setAttribute("message", "请先登录");
request.getRequestDispatcher("login.jsp").forward(request, response);
}else {
List<Cart> cartList = (List<Cart>)session.getAttribute("cartList");
Cart cart = new Cart();
cart.setProductid(Integer.valueOf(productid));
cart.setProductName(p.getName());
cart.setBaseprice(p.getBaseprice());
//数量、总价
if(cartList==null) {
//购物车为空
cart.setCount(1);
cart.setAmount(cart.getBaseprice() * cart.getCount());
cartList = new ArrayList<Cart>();
cartList.add(cart);
}else {
//flag标记是否在购物车里出现
boolean flag = true;
for(int i=0;i<cartList.size();i++) {
Cart c = cartList.get(i);
//判断商品是否在购物车里
if(c.getProductid() == Integer.parseInt(productid)) {
flag = false;
//购物车里商品数量 +1
c.setCount(c.getCount() + 1);
c.setAmount(c.getBaseprice() * c.getCount());
}
}
if(flag) {
cart.setCount(1);
cart.setAmount(cart.getBaseprice() * cart.getCount());
cartList.add(cart);
}
}
double sum = 0;
for(int i=0;i<cartList.size();i++) {
Cart c = cartList.get(i);
sum = sum + c.getAmount();
}
session.setAttribute("sum", sum);
session.setAttribute("cartList", cartList);
request.getRequestDispatcher("cart/cart.jsp").forward(request, response);
}
}

这段代码有些算法在里面，首先肯定是判断用户登陆没，只有登陆了才可以做这些操作

然后看购物车里有没有商品，购物车为空时直接添加到购物车，购物车里有商品时，取出判断，新添加的是否已在购物车，如果不在购物车就新增，否则是修改商品数量，

继而修改购物车总价。

8.购物车-从购物车中移除

这是就是对session里的值操作
首先要知道移除哪一个，即商品购物车list的序号

/*购物车是对session操作*/

public void RemoveOrClearCart(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
String count = request.getParameter("count");
HttpSession session = request.getSession();
if(count!=null) {
//count 为 该商品在list里的 id（序号）
List<Cart> cartList = (List<Cart>)session.getAttribute("cartList");
//从购物车中删除
cartList.remove(Integer.parseInt(count)-1);
double sum = 0;
for(int i=0;i<cartList.size();i++) {
Cart c = cartList.get(i);
sum = sum + c.getAmount();
}
session.setAttribute("sum", sum);
session.setAttribute("cartList", cartList);
}else {
//清空
session.removeAttribute("cartList");
session.removeAttribute("sum");
}
request.getRequestDispatcher("cart/cart.jsp").forward(request, response);
}

9.购物车-修改商品数量

<span style="white-space:pre">	</span>public void UpdateCart(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
int count = Integer.parseInt(request.getParameter("count"));
int v = Integer.parseInt(request.getParameter("v"));
//v: id（在list里的序号）   count : 数量
HttpSession session = request.getSession();
List<Cart> cartList = (List<Cart>)session.getAttribute("cartList");
Cart cart = cartList.get(v-1);
cart.setCount(count);
cart.setAmount(cart.getBaseprice() * cart.getCount());
double sum = 0;
for(int i=0;i<cartList.size();i++) {
Cart c = cartList.get(i);
sum = sum + c.getAmount();
}
session.setAttribute("sum", sum);
session.setAttribute("cartList", cartList);
request.getRequestDispatcher("cart/cart.jsp").forward(request, response);
}

10.购物车-提交订单并显示订单信息
这个不是提交订单，而是把提交订单之前的确认信息，看看jsp页面

<form id="order" method="post" action="order.do?a=OrderSubmit"/>
<table cellpadding="3" cellspacing="1" align="center" class="tableborder1" id="table1">
<tr>
<td valign="middle" colspan="2" align="center" height="25" background="images/bg2.gif">
<font color="white"><b>用户信息</b></font>

</tr>
</table>
<p align="center">请认真检查以上订单信息，确认无误后，点击 → <a href="javascript:orderSubmit()" style="cursor:hand"><img src="images/submit.gif"></a>
</form>

11.订单-修改订单信息
就是回到购物车界面，修改购物车，

12.订单-用户确认后生成正式订单
以上的全部都是单表，这里会涉及两个表，订单表和订单明显表
由于是使用了框架，所以直接新建了dao ,service
OrderDao：

public class OrderDao extends DAO{

public OrderDao(String table, String className) {
super( table, className);
}
}

OrderDetailDao：

public class OrderDetailDao extends DAO{

public OrderDetailDao(String table, String className) {
super(table,className);
}
}

Service：

public class Service extends AbstractService{

private OrderDao orderDao ;
private OrderDetailDao detailDao ;
public Service(String table_name, String bean_name) {
super(table_name, bean_name);
// TODO Auto-generated constructor stub
}
public Service() {
orderDao = new OrderDao("tbl_order","com.cl.homework.bean.Order");
detailDao = new OrderDetailDao("tbl_orderdetail","com.cl.homework.bean.OrderDetail");
}

遗憾的地方就是事务控制没有搞出来，主要问题是id主键是自动生成的，而不提交后面是查不出来新增的那个订单id的

public void OrderSubmit(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
String payType = request.getParameter("payType");
HttpSession session = request.getSession();
User user = (User)session.getAttribute("user");
double cost = Double.valueOf(session.getAttribute("sum").toString());
List<Cart> cartList = (List<Cart>)session.getAttribute("cartList");

Service orderService = new Service();
orderService.insertOrderAndDetail(cost, payType, user.getUserid(), cartList);
session.removeAttribute("cartList");
session.removeAttribute("sum");
ViewOrder(request, response);
}

13.订单-用户查看历史订单
方法都在上面的service里写好了

<span style="white-space:pre">	</span>public void ViewOrder(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
HttpSession session = request.getSession();
Service orderService = new Service();
if(session.getAttribute("user")==null) {
request.setAttribute("message", "login");
request.getRequestDispatcher("login.jsp").forward(request, response);
}else {
User user = (User)session.getAttribute("user");
List<Order> orderList = null;
try {
orderList = orderService.queryOrderByUserid(user.getUserid());
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
request.setAttribute("orderList", orderList);
request.getRequestDispatcher("order/viewOrder.jsp").forward(request, response);
}
}
public void OrderDetail(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
String orderid = request.getParameter("orderid");
Service detailService = new Service();
List<OrderDetail> detailList = null;
try {
detailList = detailService.queryDetailByOrderid(orderid);
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
request.setAttribute("detailList", detailList);
request.getRequestDispatcher("order/orderDetailList.jsp").forward(request, response);
}

最后，写的登陆界面忘了加验证码了，这里加上，框架里都提供好了

jsp页面:

<span style="white-space:pre">	</span><tr>
<td valign=middle class=tablebody1>请输入验证码</td>
<td valign=middle class=tablebody1>
<INPUT name=verifycode >
<!-- 点击刷新验证码 -->
<img alt="请点击刷新验证码" src="user.do?a=verifycode&Math.random()" onclick="this.src='user.do?a=verifycode&' + Math.random();">
</td>
</tr>

useraction里登陆部分加个验证码判断即可

<span style="white-space:pre">	</span>String verifycode = request.getParameter("verifycode").trim();

HttpSession session = request.getSession();
String VerifyCode  = session.getAttribute("VerifyCode").toString();
if(!VerifyCode.equalsIgnoreCase(verifycode)){
request.setAttribute("message", "验证码不对");
request.getRequestDispatcher("/login.jsp").forward(request, response);
}

OK，就这些了。

有需要的可以自行下载源码扩展

为什么需要 1 分，首先申明我不是缺这一分，是担心有人瞎下载源码，用作其他用途，所以加了限制，但是又不会需要你太多分

如果你需要，但是有没有分，可以私信我，或者：clseekwork@126.com，不一定及时回复哦！
