BussinessService
package service; import common.Constant; import common.Response; import entity.Goods; import java.util.ArrayList; import java.util.List; public class BusinessService { private static List<Goods> businessList = new ArrayList<>(); static { businessList.add(new Goods("1001","可口可乐","100","3","四川成都")); businessList.add(new Goods("1002","百事可乐","101","3","福建福州")); businessList.add(new Goods("1003","王老吉","102","5","河南郑州")); } public Response query(String name){ if(name == null || "".equals(name)){ return new Response("error","商品名称为空。"); } for(Goods goods : businessList){ if(name.equals(goods.getGoodsName())){ return new Response("success","查询成功。", goods); } } return new Response("error","未查询到此"+ Constant.MAIN_CLASS +"，请重新输入："); } public Response add(Goods goods){ for(Goods s : businessList){ if(s.getGoodsName().equals(goods.getGoodsName())){ return new Response("error","该"+Constant.MAIN_CLASS+"已存在。"); } } businessList.add(goods); return new Response("success",Constant.MAIN_CLASS+"添加成功。", goods); } public Response checkProp(Goods goods, String prop, String value){ if(prop == null || "".equals(prop)){ return new Response("error","属性为空。"); } switch(prop){ case "goodsNumber" : goods.setGoodsNumber(value); break; case "goodsName" : goods.setGoodsName(value); break; case "goodsStock" : goods.setGoodsStock(value); break; case "goodsPrice" : goods.setGoodsPrice(value); break; case "goodsAddress" : goods.setGoodsAddress(value); break; default: return new Response("error","该属性不存在。"); } return new Response("success","编辑成功。"); } public Response delete(String name){ if(name == null || "".equals(name)){ return new Response("error",Constant.MAIN_CLASS+"名称为空。"); } for(Goods goods : businessList){ if(goods.getGoodsName().equals(name)){ businessList.remove(goods); return new Response("success",Constant.MAIN_CLASS+"删除成功。"); } } return new Response("error",Constant.MAIN_CLASS+"不存在。"); } }
LoginService
package service; import common.Account; import common.Response; import entity.User; import java.util.ArrayList; import java.util.List; public class LoginService { private static List<User> userList = new ArrayList(); static{ userList.add(new User(Account.ADMIN.getUsername(),Account.ADMIN.getPassword())); userList.add(new User(Account.USER1.getUsername(),Account.USER1.getPassword())); userList.add(new User(Account.USER2.getUsername(),Account.USER2.getPassword())); userList.add(new User(Account.USER3.getUsername(),Account.USER3.getPassword())); } public Response login(String username, String password){ if(username == null || "".equals(username)){ return new Response("error","用户名为空，请输入用户名。"); } if(password == null || "".equals(password)){ return new Response("error","密码为空，请输入密码。"); } for (User user : userList){ if(username.equals(user.getUsername()) && password.equals(user.getPassword())){ return new Response("success","登陆成功！"); } } return new Response("error","用户名或密码输入错误，请检查并重新输入。"); } }
