This article is about how Java implements the florist mall system. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

I. brief introduction of the project

The functions of this system include:

Classified display of goods, user registration, shopping cart, order settlement, shopping cart addition and subtraction, background commodity management, classification management, order management and other functions.

II. Project operation

Environment configuration:

Jdk1.8 + Tomcat8.5 + Mysql + HBuilderX (Webstorm is also fine) + Eclispe (both supported by IntelliJ IDEA,Eclispe,MyEclispe,Sts).

Project technology:

It is composed of Springboot + Maven + mybatis+ Vue and so on, and BCMIS mode + Maven management and so on.

User management control layer:

/ * * user * * / @ RestController@RequestMapping ("user") public class UserController {@ Autowired UserService userService; @ Autowired UserDao 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 map = new HashMap () List users = userService.find (searchKey); if (users = = null) {return r.setCode (2000);} List 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);}}

Order management control layer:

/ * * user * * / @ RestController@RequestMapping ("order") public class OrderController {@ Autowired OrderService orderService; @ Autowired UserDao userDao; @ Autowired OrderDao orderDao; @ Autowired FlowersDao 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 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 map = new HashMap (); List 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 map = new HashMap () List orders = orderService.findAll (searchKey); if (orders = = null) {return r.setCode (2000);} List 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 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);}}

Shopping cart control layer:

/ * * user * * / @ RestController@RequestMapping ("cart") public class CartController {@ Autowired CartService cartService; @ Autowired OrderService orderService; @ Autowired CartDao dao; @ Autowired FlowersDao flowersDao; @ RequestMapping ("/ test") R test () {R r = new R (); return r.setCode (4000) .setMsg (Constant.IMG_PATH) .setData (dao.findAll ()) } @ 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 carts = cartService.queryByAccount (account) For (Cart cart: carts) {float price = flowersDao.queryPrice (cart.getFid ()); cart.setPrice (cart.getAmount () * price);} return r.setCode (2000) .setData (carts) } @ RequestMapping ("/ find") R find (@ RequestParam ("page") int page, @ RequestParam ("searchKey") String searchKey, @ RequestParam ("account") String account) {R r = new R (); Map map = new HashMap (); List carts = cartService.find (searchKey, account); if (carts = null) {return r.setCode (2000) } List items = carts.size () > = page * Constant.PAGE_SIZE? Carts.subList ((page-1) * Constant.PAGE_SIZE, page * Constant.PAGE_SIZE): carts.subList ((page-1) * Constant.PAGE_SIZE, carts.size ()); int len = carts.size ()% Constant.PAGE_SIZE = = 0? Carts.size () / Constant.PAGE_SIZE: (carts.size () / Constant.PAGE_SIZE + 1); map.put ("items", items); map.put ("len", len); return r.setCode (2000) .setData (map);} @ RequestMapping ("/ buy") R buy (@ RequestParam ("account") String account) {R r = new R () / / check the user's shopping cart List carts = (List) queryByAccount (account). GetData (); for (Cart cart: carts) {/ / add order data orderService.add (cart); / / delete shopping cart data cartService.delete (cart.getId ()) } return r.setCode (2000) .setMsg (HttpMsg.BUY_OK);} @ RequestMapping ("/ create") R create (@ RequestBody Cart cart) {R r = new R (); int ans = cartService.add (cart); if (ans = = 1) {return r.setCode (2000) .setMsg (HttpMsg.ADD_CART_OK) } return r.setCode (4000) .setMsg (HttpMsg.ADD_CART_FAILED);} @ RequestMapping ("/ update") R update (@ RequestBody Cart cart) {R r = new R (); int ans = cartService.update (cart); 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 = cartService.delete (id); if (ans = = 1) {return r.setCode (2000) .setMsg (HttpMsg.DELETE_USER_OK) } return r.setCode (4000) .setMsg (HttpMsg.DELETE_USER_FAILED);}} Thank you for reading!
