import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;import cn.itcast.domain.Items;
import cn.itcast.service.ItemsService;&＃64;Controller
&＃64;RequestMapping("/items")
public class ItemsController {&＃64;ResourceprivateItemsService itemsService;//查询所有商品&＃64;RequestMapping("list")publicString list(Model model){Listlist &＃61; itemsService.findAll();model.addAttribute("itemsList",list);return"itemsList";}//跳转到修改页面&＃64;RequestMapping("edit")publicString edit(Integer id , Model model){//根据Id查询商品Items items &＃61;itemsService.findByID(id);//页面回显model.addAttribute("item",items);return"editItem";}&＃64;RequestMapping("saveOrUpdate")publicString saveOrUpdate(Items items){itemsService.saveOrUpdate(items);return"redirect:list.do";}//根据Id进行删除&＃64;RequestMapping("deleteByID")publicString deleteByID(Integer id){itemsService.deleteByID(id);return"redirect: list.do";}//批量删除&＃64;RequestMapping("deleteByIds")publicString deleteByIds(Integer[] id){for(Integerids : id){itemsService.deleteByID(ids);}return"redirect: list.do";}}
