登录控制层：

@WebServlet(name = "user_login",urlPatterns = "/user_login")

public class UserLoginServlet extends HttpServlet {

private UserService uService = new UserService();

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

String ue = request.getParameter("ue");

String password = request.getParameter("password");

User user = uService.login(ue, password);

if(user==null) {

request.setAttribute("failMsg", "用户名、邮箱或者密码错误，请重新登录！");

request.getRequestDispatcher("/user_login.jsp").forward(request, response);

}else {

request.getSession().setAttribute("user", user);

request.getRequestDispatcher("/user_center.jsp").forward(request, response);

}

}

protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

}

}

商品信息列表：

@WebServlet(name = "goods_List",urlPatterns = "/goods_list")

public class GoodsListServlet extends HttpServlet {

private GoodsService gService=new GoodsService();

private TypeService tService=new TypeService();

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

}

protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

int id=0;

if(request.getParameter("typeid")!=null)

{

id=Integer.parseInt(request.getParameter("typeid"));

}

int pageNumber=1;

if(request.getParameter("pageNumber")!=null) {

try {

pageNumber=Integer.parseInt(request.getParameter("pageNumber"));

}

catch (Exception e)

{

}

}

Type t=null;

if(id!=0)

{

t=tService.selectTypeNameByID(id);

}

request.setAttribute("t",t);

//List list=gService.selectGoodsByTypeID(id,1,8);

//request.setAttribute("goodsList",list);

if(pageNumber<=0)

pageNumber=1;

Page p=gService.selectPageByTypeID(id,pageNumber);

if(p.getTotalPage()==0)

{

p.setTotalPage(1);

p.setPageNumber(1);

}

else {

if(pageNumber>=p.getTotalPage()+1)

{

p=gService.selectPageByTypeID(id,p.getTotalPage());

}

}

request.setAttribute("p",p);

request.setAttribute("id",String.valueOf(id));

request.getRequestDispatcher("/goods_list.jsp").forward(request,response);

}

}

管理员订单服务类：

@WebServlet(name = "admin_order_list",urlPatterns = "/admin/order_list")

public class AdminOrderListServlet extends HttpServlet {

private OrderService oService = new OrderService();

/**

* @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)

*/

protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

int status = 0;

if(request.getParameter("status") != null) {

status=Integer.parseInt(request.getParameter("status") ) ;

}

request.setAttribute("status", status);

int pageNumber = 1;

if(request.getParameter("pageNumber") != null) {

try {

pageNumber=Integer.parseInt(request.getParameter("pageNumber") ) ;

}

catch (Exception e)

{

}

}

if(pageNumber<=0)

pageNumber=1;

Page p = oService.getOrderPage(status,pageNumber);

if(p.getTotalPage()==0)

{

p.setTotalPage(1);

p.setPageNumber(1);

}

else {

if(pageNumber>=p.getTotalPage()+1)

{

p = oService.getOrderPage(status,pageNumber);

}

}

request.setAttribute("p", p);

request.getRequestDispatcher("/admin/order_list.jsp").forward(request, response);

}

}
