5.一:前端控制器 Controller的配置

@Controller
    @RequestMapping("/energy")
    public class IndexController {

        @RequestMapping(value = "/index")
        public ModelAndView index(HttpServletRequest request,
                                  HttpServletResponse response, ModelMap model) {

        ModelAndView mv = new ModelAndView();
        mv.setViewName("Login");
        return mv;
    }

    @Autowired
    private UserService userService;

    @RequestMapping("/login")
    public void login(HttpServletRequest req, HttpServletResponse resp) throws IOException {
        String username = req.getParameter("username");

        return mv;
    }
    @RequestMapping("/saveUser")
    public void saveUser(HttpServletRequest req, HttpServletResponse resp)
            throws IOException, ServletException, ParseException {
        String username = req.getParameter("username");
        User u = userService.getUserByUsername(username);
        String result = null;
        if (u != null) {

            String bdate = req.getParameter("birthdate");
            String dlt = req.getParameter("dltime");
            DateFormat format = new SimpleDateFormat("yyyy-MM-dd");
            Date birthdate = null;
            Date dltime = null;
            try {
                birthdate = format.parse(bdate);
                dltime = format.parse(dlt);
            } catch (ParseException e) {
                e.printStackTrace();
            }
            User user = new User();
            String id = UUID.randomUUID().toString();
            user.setId(id);
            user.setUsername(username);
            user.setPassword(password);
            user.setCreatetime(new Date());
            user.setNickname(nickname);

        } else {
            resp.getWriter().write(result);
        }
    }

6.关于UserMapper。xml的配置
