一、项目运行
环境配置：
Jdk1.8 + Tomcat8.5 + mysql + Eclispe（IntelliJ IDEA,Eclispe,MyEclispe,Sts都支持）
项目技术：
Jdbc+ Servlert + html+ css + JavaScript + JQuery + Ajax + Fileupload等等
用户登录控制层：
@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 {
}
}
订单提交控制层：
@WebServlet(name = "order_submit",urlPatterns = "/order_submit")
public class OrderSubmitServlet extends HttpServlet {
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
}
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
if(request.getSession().getAttribute("user")!=null) {
request.getRequestDispatcher("/order_submit.jsp").forward(request, response);
}else {
request.setAttribute("failMsg", "请登录后，再提交订单！");
request.getRequestDispatcher("/user_login.jsp").forward(request, response);
}
}
}
后台管理员控制层：
@WebServlet(name = "admin_user_list",urlPatterns = "/admin/user_list")
public class AdminUserListServlet extends HttpServlet {
private UserService uService = new UserService();
/**
* @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
*/
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
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 = uService.getUserPage(pageNumber);
if(p.getTotalPage()==0)
{
p.setTotalPage(1);
p.setPageNumber(1);
}
else {
if(pageNumber>=p.getTotalPage()+1)
{
p = uService.getUserPage(pageNumber);
}
}
request.setAttribute("p", p);
request.getRequestDispatcher("/admin/user_list.jsp").forward(request, response);
}
@Override
protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
this.doGet(req, resp);
}
}
后台管理商品控制层：
@WebServlet(name = "admin_goods_list",urlPatterns = "/admin/goods_list")
public class AdminGoodsListServlet extends HttpServlet {
private GoodsService gService = new GoodsService();
/**
* @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
*/
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
int type = 0;//推荐类型
if(request.getParameter("type") != null) {
type=Integer.parseInt(request.getParameter("type") ) ;
}
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 = gService.getGoodsRecommendPage(type, pageNumber);
if(p.getTotalPage()==0)
{
p.setTotalPage(1);
p.setPageNumber(1);
}
else {
if(pageNumber>=p.getTotalPage()+1)
{
p = gService.getGoodsRecommendPage(type, pageNumber);
}
}
request.setAttribute("p", p);
request.setAttribute("type", type);
request.getRequestDispatcher("/admin/goods_list.jsp").forward(request, response);
}
/**
* @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
*/
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
doGet(request, response);
}
}
