自定义商品对象，可根据自己的需求进行设计

/*** 菜品对象* @author admin* */
public class Test {// 菜品名称private String name;// 价格private double money;// 数量private Integer num;//菜品分类private String fenlei;public Test() {super();}public Test(String name, double money, Integer num,String fenlei) {super();this.name = name;this.money = money;this.num = num;this.fenlei=fenlei;}public String getName() {return name;}public void setName(String name) {this.name = name;}public double getMoney() {return money;}public void setMoney(double money) {this.money = money;}public Integer getNum() {return num;}public void setNum(Integer num) {this.num = num;}public String getFenlei() {return fenlei;}public void setFenlei(String fenlei) {this.fenlei = fenlei;}
}

打印模板，这里设计一个小票模板

import java.util.ArrayList;
import java.util.List;
/*** 小票模板* * @author admin* */
public class Prient{// 菜品集合--传入一个商品集合public static List<Test> testList = new ArrayList<Test>();public static double ZMoney=0;public static double YMoney=20;public static double SMoney=500;// 设置小票打印public static String print(){//字符串拼接StringBuilder sb=new StringBuilder();sb.append("<center>点菜清单\r\n</center>");sb.append("------------------------------------\r\n");sb.append("点餐员：测试打印\r\n");sb.append("电话：13408086368\r\n");sb.append("用餐时间：2015-04-09 13:01-13:30\r\n");sb.append("用餐地址：打印测试\r\n");sb.append("------------------------------------\r\n");sb.append("<table>");sb.append("<tr>");sb.append("<td>");sb.append("菜品");sb.append("</td>");sb.append("<td>");sb.append("单价");sb.append("</td>");sb.append("<td>");sb.append("小计");sb.append("</td>");sb.append("</tr>");for (Test test : testList) {ZMoney=ZMoney+(test.getMoney()*test.getNum());sb.append("<tr>");sb.append("<td>"+test.getName()+"</td>");sb.append("<td>"+test.getMoney()+"</td>");sb.append("<td>"+test.getMoney()*test.getNum()+"</td>");sb.append("</tr>");}sb.append("</table>");sb.append("------------------------------------\r\n");sb.append("合计：￥"+ZMoney+"\r\n");sb.append("优惠金额：￥"+YMoney+"\r\n");sb.append("应收：￥"+(ZMoney-YMoney)+"\r\n");sb.append("实收：￥"+SMoney+"\r\n");sb.append("找零：￥"+(SMoney-YMoney)+"\r\n");sb.append("收银员：打印测试\r\n");sb.append("<center>谢谢惠顾，欢迎下次光临！</center>");return sb.toString();}public static List<Test> getTestList() {return testList;}public static void setTestList(List<Test> testList) {Prient.testList = testList;}
}

控制器，这里可以自己定义，用于测试
