用户控制层：

/*** 用户**/
@RestController
@RequestMapping("user")
public class UserController {@AutowiredUserService userService;@AutowiredUserDao dao;@RequestMapping("/test")R test() {R r = new R();return r.setCode(4000).setMsg(Constant.IMG_PATH).setData(dao.findAll());}@RequestMapping("/queryInfoByAccount")R queryInfoByAccount(@RequestParam("account") String account) {R r = new R();if (StringUtil.isEmpty(account)){return r.setCode(4000).setMsg(HttpMsg.INVALID_PARAM);}User loginUser = userService.queryInfo(account);if (loginUser == null){return r.setCode(4000).setMsg(HttpMsg.INVALID_USER);}return r.setCode(2000).setData(loginUser);}@RequestMapping("/find")R find(@RequestParam("page") int page, @RequestParam("searchKey") String searchKey) {R r = new R();Map<String, Object> map = new HashMap<>();List<User> users = userService.find(searchKey);if (users == null) {return r.setCode(2000);}List<User> items = users.size() >= page * Constant.PAGE_SIZE ?users.subList((page - 1) * Constant.PAGE_SIZE, page * Constant.PAGE_SIZE): users.subList((page - 1) * Constant.PAGE_SIZE, users.size());int len = users.size() % Constant.PAGE_SIZE == 0 ? users.size() / Constant.PAGE_SIZE: (users.size() / Constant.PAGE_SIZE + 1);map.put("items", items);map.put("len", len);return r.setCode(2000).setData(map);}@RequestMapping("/create")R create(@RequestBody User user) {R r = new R();int ans = userService.add(user);if (ans == 1) {return r.setCode(2000).setMsg(HttpMsg.ADD_USER_OK);}return r.setCode(4000).setMsg(HttpMsg.ADD_USER_FAILED);}@RequestMapping("/update")R update(@RequestBody User user) {R r = new R();int ans = userService.update(user);if (ans >= 0) {return r.setCode(2000).setMsg(HttpMsg.UPDATE_USER_OK);}return r.setCode(4000).setMsg(HttpMsg.UPDATE_USER_FAILED);}@DeleteMapping("/delete")R delete(@RequestParam("id") int id) {R r = new R();int ans = userService.delete(id);if (ans == 1) {return r.setCode(2000).setMsg(HttpMsg.DELETE_USER_OK);}return r.setCode(4000).setMsg(HttpMsg.DELETE_USER_FAILED);}
}

订单控制层：

/*** 订单控制层**/
@RestController
@RequestMapping("order")
public class OrderController {@AutowiredOrderService orderService;@AutowiredUserDao userDao;@AutowiredOrderDao orderDao;@AutowiredFlowersDao flowersDao;@RequestMapping("/test")R test() {R r = new R();return r.setCode(4000).setMsg(Constant.IMG_PATH).setData(orderDao.findAll(null));}@RequestMapping("/queryByAccount")R queryByAccount(@RequestParam("account") String account) {R r = new R();if (StringUtil.isEmpty(account)) {return r.setCode(4000).setMsg(HttpMsg.INVALID_PARAM);}List<Order> orders = orderService.queryByAccount(account);return r.setCode(2000).setData(orders);}@RequestMapping("/find")R find(@RequestParam("page") int page, @RequestParam("searchKey") String searchKey, @RequestParam("account") String account) {R r = new R();Map<String, Object> map = new HashMap<>();List<Order> orders = orderService.find(searchKey, account);if (orders == null) {return r.setCode(2000);}map.put("items", orders);map.put("len", orders.size());return r.setCode(2000).setData(map);}@RequestMapping("/findAll")R findAll(@RequestParam("page") int page, @RequestParam("searchKey") String searchKey) {R r = new R();Map<String, Object> map = new HashMap<>();List<Order> orders = orderService.findAll(searchKey);if (orders == null) {return r.setCode(2000);}List<Order> items = orders.size() >= page * Constant.PAGE_SIZE ?orders.subList((page - 1) * Constant.PAGE_SIZE, page * Constant.PAGE_SIZE): orders.subList((page - 1) * Constant.PAGE_SIZE, orders.size());int len = orders.size() % Constant.PAGE_SIZE == 0 ? orders.size() / Constant.PAGE_SIZE: (orders.size() / Constant.PAGE_SIZE + 1);List<OrderVo> vos = new ArrayList<>();for (Order item : items) {User user = userDao.queryById(item.getUid());OrderVo vo = new OrderVo();vo.setAddress(user.getAddress()).setPhone(user.getPhone()).setUsername(user.getName()).setAmount(item.getAmount()).setFlower(item.getFlower()).setId(item.getId()).setUid(item.getUid()).setOrder_guid(item.getOrder_guid()).setPrice(item.getPrice()).setState(item.getState());vos.add(vo);}map.put("items", vos);map.put("len", len);return r.setCode(2000).setData(map);}@RequestMapping("/update")R update(@RequestBody Order order) {R r = new R();int ans = orderService.update(order);if (ans >= 0) {return r.setCode(2000).setMsg(HttpMsg.UPDATE_USER_OK);}return r.setCode(4000).setMsg(HttpMsg.UPDATE_USER_FAILED);}@RequestMapping("/changeState")R changeState(@RequestBody Order order) {orderDao.changeState(order);return new R().setCode(2000).setMsg(HttpMsg.UPDATE_ORDER_OK);}@DeleteMapping("/delete")R delete(@RequestParam("id") int id) {R r = new R();int ans = orderService.delete(id);if (ans == 1) {return r.setCode(2000).setMsg(HttpMsg.DELETE_USER_OK);}return r.setCode(4000).setMsg(HttpMsg.DELETE_USER_FAILED);}
}

用户登录控制层：

/*** 登录**/
@RestController
@RequestMapping("login")
public class LoginController {@AutowiredLoginDao loginDao;@RequestMapping("/doLogin")R doLogin(@RequestBody LoginForm form) {R r = new R();if (!VerifyUtil.verifyLoginForm(form)) {return r.setCode(4000).setMsg(HttpMsg.ERROR_INPUT);}User loginUser = loginDao.login(form);if (loginUser != null) {return r.setCode(2000).setMsg("欢迎您：" + loginUser.getName()).setData(loginUser);}return r.setCode(4000).setMsg(HttpMsg.ERROR_VERIFY);}@RequestMapping("/test")R test() {R r = new R();return r.setCode(4000).setMsg(Constant.IMG_PATH);}}
