一、项目简述
本系统功能包括:
商品的分类展示,用户的注册登录,购物车,订单结算,购物车加减,后台商品管理,分类管理,订单管理等等功能。
二、项目运行
环境配置:
jdk1.8 + tomcat8.5 + mysql + hbuilderx(webstorm也行)+ eclispe(intellij idea,eclispe,myeclispe,sts都支持)。
项目技术:
springboot + maven + mybatis+ vue 等等组成,b/s模式 + maven管理等等。
用户管理控制层:
/** * 用户 **/ @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<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); } }
订单管理控制层:
/** * 用户 **/ @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<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); } }
购物车控制层:
/** * 用户 **/ @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<cart> 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<string, object> map = new hashmap<>(); list<cart> carts = cartservice.find(searchkey, account); if (carts == null) { return r.setcode(2000); } list<cart> 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(); // 查该用户的购物车 list<cart> carts = (list<cart>) querybyaccount(account).getdata(); for (cart cart : carts) { // 增加订单数据 orderservice.add(cart); // 删除购物车数据 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); } }
