model.addAttribute(“item“, items )； jsp页面无法通过EL表达式${item}获取。解决办法。

ItemController.java

@Controller
@RequestMapping("/items")
public class ItemsController {

    @Autowired
    private ItemsService itemsService;

    @RequestMapping("/showDetail")
    public String showDetail(Model model){
        Items items = itemsService.findById(1);
        model.addAttribute("item", items );
        System.out.println(model.asMap()+"ssss");
        return "itemDetail";
    }
}

index.jsp
