二：前台的控制器：

1.AddressController前台收获地址控制器

@Controller
public class AddressController {
	@Autowired
	private AccountService accountService;

public class CartController {
	@Autowired
	private AccountService accountService;
	@Autowired
	private ProductCategoryService productCategoryService;
	@Autowired
	private ProductService productService;
	@Autowired
	private CartService cartService;
	@Autowired
	private AddressService addressService;

3.FavoriteController前台收藏控制器

@RequestMapping("/favorite")
@Controller
public class FavoriteController {
	@Autowired
	private AccountService accountService;
	@Autowired
	private ProductCategoryService productCategoryService;
	@Autowired
	private ProductService productService;
	@Autowired
	private FavoriteService favoriteService;

4.HomeCommenController前台评价控制器

@RequestMapping("/comment")
@Controller
public class HomeCommentController {
	@Autowired
	private AccountService accountService;
	@Autowired
	private ProductCategoryService productCategoryService;
	@Autowired
	private ProductService productService;
	@Autowired
	private CommentService commentService;

5.HomeOrderController前台订单控制器

@RequestMapping("/order")
@Controller
public class HomeOrderController {
	@Autowired
	private AccountService accountService;
	@Autowired
	private ProductCategoryService productCategoryService;
	@Autowired
	private ProductService productService;
	@Autowired
	private OrderService orderService;
	@Autowired
	private CartService cartService;
	@Autowired
	private AddressService addressService;

6.HomeProductController前台商品控制器

@RequestMapping("/product")
@Controller
public class HomeProductController {
	@Autowired
	private AccountService accountService;
	@Autowired
	private ProductCategoryService productCategoryService;
	@Autowired
	private ProductService productService;
	@Autowired
	private CommentService commentService;

7.HomeUserController前台用户中心控制器

@RequestMapping("/user")
@Controller
public class HomeUserController {
	@Autowired
	private AccountService accountService;
	@Autowired
	private ProductCategoryService productCategoryService;
	@Autowired
	private ProductService productService;
	@Autowired
	private OrderService orderService;
	@Autowired
	private CartService cartService;
	@Autowired
	private AddressService addressService;

8.IndexController前台首页控制器

@RequestMapping("/home")
@Controller
public class IndexController {
	@Autowired
	private AccountService accountService;
	@Autowired
	private ProductCategoryService productCategoryService;
	@Autowired
	private ProductService productService;

三：前台的dao层：

1.addressDao收货地址dao层

2.CartDao购物车dao层

3.FavoriteDao收藏dao层

四：前台的实体entity：

1.Address收货地址实体

@Component
public class Address {
	private Long id;//id
	private Long userId;//用户id
	private String name;//收货人姓名
	private String address;//详细地址
	private String phone;//手机号码
	private Date createTime;//添加时间

2.Cart购物车实体

@Component
public class Cart {
	private Long id;//id
	private Long productId;//商品id
	private Long userId;//用户id
	private String name;//商品名称
	private String imageUrl;//商品主图
	private Double price;//商品价格
	private int num;//商品数量
	private Double money;//商品价格
	private Date createTime;//添加时间

3.Favorite收藏实体

@Component
public class Favorite {
	private Long id;//id
	private Long productId;//商品id
	private Long userId;//用户id
	private String name;//商品名称
	private String imageUrl;//商品主图
	private Double price;//商品价格
	private Date createTime;//添加时间

五：前台的interceptor拦截器:

LoginInterceptor拦截器

/**
 * 前台登录拦截器
 * @author llq
 *
 */
public class LoginInterceptor implements HandlerInterceptor {
	@Override
	public void afterCompletion(HttpServletRequest arg0,
			HttpServletResponse arg1, Object arg2, Exception arg3)
			throws Exception {
		// TODO Auto-generated method stub
	}
	@Override
	public void postHandle(HttpServletRequest arg0, HttpServletResponse arg1,
			Object arg2, ModelAndView arg3) throws Exception {
		// TODO Auto-generated method stub
	}
	@Override
	public boolean preHandle(HttpServletRequest request, HttpServletResponse response,
			Object arg2) throws Exception {
		// TODO Auto-generated method stub
		String requestURI = request.getRequestURI();
		Object account = request.getSession().getAttribute("account");
		if(account == null){
			//表示未登录或者登录失效
			System.out.println("链接"+requestURI+"进入拦截器！");
			String header = request.getHeader("X-Requested-With");
			//判断是否是ajax请求
			if("XMLHttpRequest".equals(header)){
				//表示是ajax请求
				Map<String, String> ret = new HashMap<String, String>();
				ret.put("type", "error");
				ret.put("msg", "登录会话超时或还未登录，请重新登录!");
				response.getWriter().write(JSONObject.fromObject(ret).toString());
				return false;
			}
			//表示是普通链接跳转，直接重定向到登录页面
			response.sendRedirect(request.getServletContext().getContextPath() + "/home/login");
			return false;
		}
		return true;
	}
}

六：前台的service以及serviceImpl:

收货地址接口AddressService

AddressServiceimpl实现类

Service方法同上面的dao层方法
ServiceImpl实现方法类似上面，这里不再赘述！！

七：前台的mapper映射文件：

1.AddressMapper.xml收货映射文件

2.CartMapper.xml购物车映射文件

3.FavoriteMapper.xml收藏映射文件

至此，前台的界面和管理系统的大致已经介绍完毕！
