[Java知识库]SSM框架实战之超市账单管理系统

????????根据所学知识以及材料模板，开发了基于SSM框架的超市账单管理系统，其中涉及到了各个模块的增删改查以及导出数据功能，初学者可以拿来练练手，部分代码如下，喜欢的小伙伴可以在关赞收后可以找我要源码噢！

@Controller
public class TbbillController {

?? ?@Autowired
?? ?private TbbillService tbbillService;

?? ?public String addBill(Tbbill bill) {
?? ??? ?
?? ??? ?tbbillService.insert(bill);
?? ??? ?return "redirect:findBillByPage.action";
?? ?}

?? ?@RequestMapping("findBillByPage")
?? ?public String findBillByPage(String uname, Integer ispay, Integer nowPage, Model model) {

?? ??? ?PageService page = new PageService();
?? ??? ?page.setGoodsname(uname);

?? ??? ?page.setNowPage(nowPage);
?? ??? ?
?? ??? ?System.out.println("总记录数："+tbbillService.getBillCount(page));
