二、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: JSP + C3P0+ Servlert + html+ css + JavaScript + JQuery + Ajax + Fileupload

用户登录模块代码:

用户登录模块:
 
@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 {
 
    }
}

管理员添加用户代码:

管理员添加用户:
 
@WebServlet(name = "admin_user_add",urlPatterns = "/admin/user_add")
public class AdminUserAddServlet extends HttpServlet {
    private UserService uService = new UserService();
    /**
     * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
     */
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        User user = new User();
        try {
            BeanUtils.copyProperties(user, request.getParameterMap());
        } catch (IllegalAccessException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (InvocationTargetException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        if(uService.register(user)) {
            request.setAttribute("msg", "客户添加成功!");
            request.getRequestDispatcher("/admin/user_list").forward(request, response);
        }else {
            request.setAttribute("failMsg", "用户名或邮箱重复,请重新填写!");
            request.setAttribute("u",user);
            request.getRequestDispatcher("/admin/user_add.jsp").forward(request, response);
        }
    }
}
