四 系统实现

4.1 功能模块实现说明

（1）商品管理：

4.1.1 商品管理

后台可以通过该功能模块实现商品上架、商品下架、修改商品信息、查看商品。通过该模块将指定的商品信息增加到数据库中，实现商品上架功能。通过该模块将商城已有商品的商品数目改为0，实现下架商品功能。通过该模块在数据库内修改指定的商品信息，实现修改商品信息功能。

用户通过该模块实现在前台页面查看和搜索商品，并浏览商品。

相关代码：

//商品分类
	@RequestMapping("/admin/orderBy")
	public String orderBy(String cid,String price,String amount,HttpServletRequest request) {
    
    
		List<Product> productList = null;
		System.out.println("cid:"+cid+"  price:"+price+ "  amount:"+amount);
		if(cid != null) {
    
    
			productList = service.getProductByDetails(cid,price,amount);
		}
		request.setAttribute("productList", productList);
		
		return "admin/newProductManage";
	}
	
	//弹窗展示获得的商品数据
	@RequestMapping("/admin/showProductInfo")
	public void showProduct(String pid,HttpServletRequest request,HttpServletResponse response) throws IOException {
    
    
		Product product = productservice.getProductInfo(pid);
		Gson gson = new Gson();
		String json = gson.toJson(product);
		response.getWriter().write(json);
	}
	@RequestMapping("/admin/modifyProduct")
	public void modifyProduct(Product product,HttpServletResponse response) throws IOException {
    
    
		System.out.println(product.getPid());
		productservice.modifyProduct(product);
		response.getWriter().write("{\"isSuc\":"+true+"}");

4.1.2 分类管理

后台可以通过该功能模块实现增加商品分类，修改商品分类以及删除商品分类等功能要求。对应在数据库中对分类信息进行增删改。

用户通过该功能模块实现商品的分类浏览。

相关代码：

AdminController:
@RequestMapping("/admin/orderManage")
	public String orderManage(HttpServletRequest request) {
    
    
		List<Order> orderList = orderservice.getAllOrder();

		Gson gson = new Gson();
		String json = gson.toJson(orderList);
		request.setAttribute("orderList", orderList);
		request.setAttribute("json", json);
		return "admin/orderManage";
	}
productController:
@RequestMapping("/productByCategory")
	public String getOrderByUser(String cid, @RequestParam(value = "currentPage", defaultValue = "1") int currentPage,
			HttpServletRequest request) {
    
    
		PageBean pagebean = service.getProductListByCid(cid, currentPage);
		request.setAttribute("pageBean", pagebean);
		request.setAttribute("cid", cid);
		return "productList";
	}

4.1.3 订单管理

用户通过该模块查看自己的订单信息、提交订单、删除订单以及更改订单收货状态。

后台通过该模块查看所有用户的订单信息以及更改订单的发货状态。

4.1.4 用户权限

用户权限分为一般浏览者和买家。一般浏览者可以查看所有商品信息，但是不能购买商品以及没有个人中心，在选择购买时会跳到用户注册登录界面。买家则是已登录的用户，可以购买商品也拥有自己的个人中心，可查看自己的个人信息。

相关代码：

UserInterceptor.java 登录拦截器：
public class UserInterceptor implements HandlerInterceptor {
    
    
	
	@Override
	public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object arg2) throws Exception {
    
    
		HttpSession session = request.getSession();
		Object user = session.getAttribute("user");
		if(user != null) {
    
    
			return true;
		}else {
    
    
			response.sendRedirect(request.getContextPath()+"/login.html");
		}
		return false;
	}

4.1.5 注册与登录

用户只有在登录后才可以购买商品以及查看个人信息，没有账户的游客则需要进行注册再登录。

图25 注册新账号

相关代码：

UserConroller：
@RequestMapping("/login")
	public void login(String account, String password, HttpServletRequest request, HttpServletResponse response)
			throws Exception {
    
    
		String email = "";
		String username = "";
		boolean flag = false;
		try {
    
    
			String check = "^([a-z0-9A-Z]+[-|_|\\.]?)+[a-z0-9A-Z]@([a-z0-9A-Z]+(-[a-z0-9A-Z]+)?\\.)+[a-zA-Z]{2,}$";
			Pattern regex = Pattern.compile(check);
			Matcher matcher = regex.matcher(account);
			flag = matcher.matches();
		} catch (Exception e) {
    
    
			flag = false;
		}
		if (flag) {
    
    
			email = account;
		} else {
    
    
			username = account;
		}

		System.out.println("email:" + email);
		System.out.println("username:" + username);
		User user = new User();
		user.setUsername(username);
		user.setEmail(email);
		user.setPassword(password);

		User logined = service.login(user);

		boolean isSuccess = true;
		System.out.println(logined);
		HttpSession session = request.getSession();
		if (logined != null) {
    
    
			session.setAttribute("user", logined);
			response.getWriter().write("{\"isSuccess\":" + isSuccess + "}");
		}else {
    
    
			isSuccess = false;
			response.getWriter().write("{\"isSuccess\":" + isSuccess + "}");
		}

	}

4.1.6 浏览商品

所有人都可以浏览商品。

在这里插入图片描述

相关代码：

ProductController：
//根据pid展示商品
	@RequestMapping("/product")
	public String productInfo(String pid, HttpServletRequest request) {
    
    

		Product product = service.getProductInfo(pid);
		request.setAttribute("product", product);

		return "productInfo";
	}

indexController：
//展示最新和热门商品
@RequestMapping(value = {
    
    "/","/index"})
	public String index(Model model) {
    
    
		
		List<Product> hotProductList = indexservice.getHotProducts();
		List<Product> newProductList = indexservice.getNewProducts();
		model.addAttribute("hotProductList", hotProductList);
		model.addAttribute("newProductList", newProductList);
		
		return "index";
	}

4.1.7 用户信息管理

用户可以在这里查看自己的所有信息，以及地址管理和充值服务。

相关代码：

userController：
@RequestMapping("/user/userInfo")
	public String toUserInfo() {
    
    
		return "privilege/userInfo";
	}
	// 修改用户信息
	@RequestMapping("/user/modify")
	public void modifyUserInfo(User user, HttpServletRequest request, HttpServletResponse response) throws Exception {
    
    
		System.out.println(user);

		service.modifyUserInfo(user);
		User newUser = service.getUser(user.getUid());
		HttpSession session = request.getSession();
		Boolean isSuccess = false;
		if (newUser != null) {
    
    
			isSuccess = true;
			session.setAttribute("user", newUser);
		}
		response.getWriter().write("{\"isSuccess\":" + isSuccess + "}");
	}

	// 前往充值余额页面
	@RequestMapping("/user/balance")
	public String toBalancePage() {
    
    
		return "privilege/balance";
	}
	// 充值余额
	@RequestMapping("/user/recharge")
	public void recharge(Double pay, HttpServletRequest request, HttpServletResponse response) throws Exception {
    
    
		HttpSession session = request.getSession();
		User user = (User) session.getAttribute("user");
		Double money = user.getMoney();
		Double newMonney = 0.0;
		if (pay != 0.0 && pay != null) {
    
    
			newMonney = money + pay;
		}
		System.out.println("money:" + newMonney);
		user.setMoney(newMonney);

		service.modifyUserInfo(user);
		user = service.getUser(user.getUid());
		System.out.println(user);
		session.setAttribute("user", user);
		Boolean isSuccess = false;
		if (user.getUid() != "") {
    
    
			isSuccess = true;
		}
		response.getWriter().write("{\"isSuccess\":" + isSuccess + "}");
}
	// 跳转到支付成功页面
	@RequestMapping("/user/paySuccess")
	public String topaySuccessPage() {
    
    
		return "privilege/recharge";
	}

	// getAddsByUser
	@RequestMapping("/user/address")
	public String addressManage(HttpServletRequest request) {
    
    
		HttpSession session = request.getSession();
		User user = (User) session.getAttribute("user");
		List<Address> addList = service.getAddress(user.getUid());
		request.setAttribute("addList", addList);
		
		return "privilege/addManage";
	}
	
	// 添加或修改用户地址
	@RequestMapping("/user/addManage")
	public String addManage(String aid,String tel,String address,String name,HttpServletRequest request) {
    
    
		System.out.println(aid);
		System.out.println(tel);
		System.out.println(address);
		System.out.println(name);
		
		Address address1 = new Address();
		address1.setAid(aid);
		address1.setTel(tel);
		address1.setAddress(address);
		address1.setName(name);
		
		System.out.println(address1);
		HttpSession session = request.getSession();
		User user = (User)session.getAttribute("user");
		address1.setUid(user.getUid());
		System.out.println(address1);
		if(address1.getAid() != null && address1.getAid() != "") {
    
    
			service.updateAdd(address1);
		}else {
    
    
			service.addAddress(address1);
		}
		
		return "redirect:/user/address";
	}
	
	//删除地址
	@RequestMapping("/user/delAdd")
	public String delAdd(@RequestParam(value = "aid") String aid) {
    
    
		Address address = new Address();
		address.setAid(aid);
		
		service.delAdd(address);
		
		return "redirect:/user/address";
	}
	
	//设置默认地址
	@RequestMapping("/user/setDefaultAdd")
	public String setDefaultAdd(String aid,HttpServletRequest request) {
    
    
		HttpSession session = request.getSession();

		List<Address> addList = service.getAddress(user.getUid());
		
		session.setAttribute("addListCart", addList);
		
		return "redirect:/cart.html";
		
	}

4.18 购物车模块

用户可以将自己心仪的商品先添加至购物车，然后继续浏览其他商品，最后再进行付款提交订单。

图35 购物车为空

相关代码：

Productcontroller:
// 加入购物车
	@RequestMapping("/addCart")
	public String addCart(String pid, int buyNum, HttpServletRequest request) {
    
    
		HttpSession session = request.getSession();

		Cart cart = (Cart) session.getAttribute("cart");
		if (cart == null) {
    
    
			cart = new Cart();
		}
		CartItem cartitem = new CartItem();
		Product product = service.getProductInfo(pid);
		cartitem.setProduct(product);
		cartitem.setBuyNum(buyNum);

		double subtotal = product.getPrice() * buyNum;
		cartitem.setSubtotal(subtotal);
		
		double total = 0.0d;
		Map<String, CartItem> cartItems = cart.getCartItems();
		if(cartItems.containsKey(pid)) {
    
    
			CartItem item = cartItems.get(pid); 
			int oldNum = item.getBuyNum();
			int newNum = oldNum+buyNum;
			item.setBuyNum(newNum);
			item.setSubtotal(product.getPrice()*newNum);
			cart.setCartItems(cartItems);
		}else {
    
    
			cartItems.put(pid, cartitem);
		}
		
		total = cart.getTotal()+cartitem.getSubtotal();
		cart.setTotal(total);
		User user = (User) session.getAttribute("user");
		if (user != null) {
    
    
			List<Address> address = userservice.getAddress(user.getUid());
			System.out.println(address);
			session.setAttribute("addListCart", address);
		}
		session.setAttribute("cart", cart);
		return "redirect:/cart.html";
	}
	
	@RequestMapping("/delCartItem")
	public String delCartItem(String pid,HttpServletRequest request) {
    
    
		HttpSession session = request.getSession();
		Cart cart = (Cart) session.getAttribute("cart");
		if(cart!=null) {
    
    
			Map<String, CartItem> cartItems = cart.getCartItems();
			//修改总价
			double  newTotal = cart.getTotal() - cartItems.get(pid).getSubtotal();
			cart.setTotal(newTotal);
			// 删除
			cartItems.remove(pid);
			cart.setCartItems(cartItems);
		}
		session.setAttribute("cart", cart);
		return "redirect:/cart.html";
	}
	@RequestMapping("/removeCart")
	public String removeCart(HttpServletRequest request) {
    
    
		HttpSession session = request.getSession();
		session.removeAttribute("cart");
		
		return "redirect:/cart.html";
		
	}

4.2 配置文件

ApplicationContext.xml是web应用中spring框架的配置文件，负责对web系统中beanfactory和各个bean的属性注入以及数据库连接池的配置设置。

部分配置代码如下：

<context:property-placeholder
		location="classpath:db.properties" />
	<bean id="dataSource"
		class="org.apache.commons.dbcp.BasicDataSource">
		<property name="driverClassName" value="${jdbc.driver}" />
		<property name="url" value="${jdbc.url}" />
		<property name="username" value="${jdbc.username}" />
		<property name="password" value="${jdbc.password}" />
		<property name="maxActive" value="10" />
		<property name="maxIdle" value="5" />
	</bean>

	<!-- sqlSessionFactory -->
	<bean id="sqlSessionFactory"
		class="org.mybatis.spring.SqlSessionFactoryBean">
		<!-- mybatis核心配置 -->
		<property name="configLocation"
			value="classpath:SqlMapConfig.xml"></property>
		<!-- 数据源 -->
		<property name="dataSource" ref="dataSource" />
	</bean>
	<!-- mapper扫描器 -->
	<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
		<property name="basePackage" value="cn.fpshop.dao" />
	</bean>

Springmvc.xml是基于SSM的web系统中SpringMVC的配置文件。负责对springmvc的核心组件前端控制器、处理器等进行配置

=“${jdbc.password}” />

<!-- sqlSessionFactory -->
<bean id="sqlSessionFactory"
	class="org.mybatis.spring.SqlSessionFactoryBean">
	<!-- mybatis核心配置 -->
	<property name="configLocation"
		value="classpath:SqlMapConfig.xml"></property>
	<!-- 数据源 -->
	<property name="dataSource" ref="dataSource" />
</bean>
<!-- mapper扫描器 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
