2. 在controller中获取spring容器实例
@Controller("accountController") //让spring管理Controller @RequestMapping("/accountController.do") @SessionAttributes({"account"}) //put account to session, //as a result both request and session have the two attribute. public class AccountController { @Resource //自动注入Service实例 AccountService accountService; @RequestMapping(params="method=login", method=RequestMethod.POST) public String login(String username, String password, ModelMap map, HttpServletRequest request){ Account account = accountService.Login(username, password); if(account!=null){ //request.getSession().setAttribute("account", account); System.out.println("Hello "+ username); map.put("message", "welcome "+ username +"!"); return "main"; }else{ map.put("message", "username or password is wrong! "); return "index"; } } @RequestMapping(params="method=register", method=RequestMethod.POST) public ModelAndView register(Account account, HttpServletRequest request){ ModelAndView mav =new ModelAndView("main"); mav.addObject("account", account); try { accountService.reqister(account); } catch (Exception e) { e.printStackTrace(); mav.addObject("message", "register failed!"); mav =new ModelAndView("account/account_register"); } mav.addObject("message", "register successed!"); mav =new ModelAndView("main"); return mav; } }
