用户管理控制层：
@Controller @RequestMapping("UsersServlet") public class UsersController { private UsersDao usersDao = new UsersDao(); @Autowired private HttpServletRequest request; @RequestMapping("/loginadmin") public String loginadmin() { String username = request.getParameter("username"); String password = request.getParameter("password"); Users users = usersDao.login(username, password); if (users != null) { request.getSession().setAttribute("loginUsers", users); return "admin_index"; } else { request.setAttribute("msg", "登录失败，账号密码不匹配"); return "admin_login"; } } @RequestMapping("/userlogin") public String userlogin() { String userName = request.getParameter("username"); String password = request.getParameter("password"); String clientCheckcode = request.getParameter("validateCode"); String serverCheckcode = (String) request.getSession().getAttribute("checkcode"); if (clientCheckcode.equals(serverCheckcode)) { // 2. 去访问dao ， 看看是否满足登录。 Users Users = usersDao.userlogin(userName, password); // 3. 针对dao的返回结果，做出响应 if (Users != null) { request.getSession().setAttribute("usersLogin", Users); CategoryDao categoryDao = new CategoryDao(); List<Category> categoryList = categoryDao.queryAll(); request.setAttribute("categoryList", categoryList.stream().filter(x -> x.getState().equals("1")).collect(Collectors.toList())); return "index"; } else { request.setAttribute("error", "用户名或密码错误！"); return "login"; } } else { request.setAttribute("error", "登录失败，验证码不正确！"); return "login"; } } @RequestMapping("/userreg") public String userreg() { String username = request.getParameter("username"); String password = request.getParameter("password"); String account = request.getParameter("account"); String email = request.getParameter("email"); String password2 = request.getParameter("password2"); if (!password.equals(password2)) { request.setAttribute("error", "注册失败，密码与确认密码不一致！"); return "reg"; } else { boolean isSuccess = usersDao.isReg(account); if (!isSuccess) { request.setAttribute("error", "注册失败，该用户名已存在！"); return "reg"; } else { usersDao.reg(username, account, password, email); request.setAttribute("error", "注册成功！"); return "reg"; } } } @RequestMapping("/listforadmin") public String listforadmin() { List<Users> list = usersDao.getUsers(); request.setAttribute("list", list); return "listusers"; } @RequestMapping("/del") public String del(Integer id) { usersDao.del(id); List<Users> list = usersDao.getUsers(); request.setAttribute("list", list); return "listusers"; } }
