业务层代码

@Service
public class ItemServiceImp implements ItemService {
@Autowired
private IDao iDao;

@Override
public Item findById(Integer i) {
    return iDao.findById(i);
}
}

控制器代码

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

@Autowired
private ItemService itemService;


@RequestMapping("/findById")
public ModelAndView  findById(ModelAndView model){
    Item item = itemService.findById(1);
    String s = item.toString();
    model.addObject("item",item);
    model.setViewName("list");
    return model;

}

}

测试代码

public class Testclass {

@Test
public void findById()
{
    ApplicationContext ac = new       ClassPathXmlApplicationContext("applicationContext.xml");
//        IDao iDao = ac.getBean(IDao.class);
//        Item i = iDao.findById(1);
    ItemService service = ac.getBean(ItemService.class);
    Item i = service.findById(1);
    System.out.println(i);
}

}
