整合Dao層

創(chuàng)建SqlMapConfig.xml配置文件

Spring整合mybatis渊跋，創(chuàng)建applicationContext-dao.xml

測(cè)試

ItemServiceImpl.java

@Service
public class ItemServiceImpl implements ItemService{
    //注入mapper代理對(duì)象
    @Autowired
    private TbItemMapper itemMapper;

    @Override
    public TbItem geTbItemById(long itemId) {
        // TbItem tbItem = itemMapper.selectByPrimaryKey(itemId);
        TbItemExample example = new TbItemExample();
        // 創(chuàng)建example對(duì)象，添加查詢(xún)條件
        Criteria criteria = example.createCriteria();
        criteria.andIdEqualTo(itemId);
        List<TbItem> list = itemMapper.selectByExample(example);
        if (list != null && list.size() > 0) {
            return list.get(0);
        }
        return null;
    }

ItemController.java

@Controller
public class ItemController {
    @Autowired
    private ItemService itemService;

    /**
     * 根據(jù)id來(lái)查詢(xún)商品信息
     */
    @RequestMapping("/item/{itemId}")
    @ResponseBody
    public TbItem getTbItem(@PathVariable Long itemId) {
        return itemService.geTbItemById(itemId);
    }
}

在瀏覽器輸入：http://localhost:8080/item/536563
得到j(luò)son數(shù)據(jù)：

{"id":536563,"title":"new2 - 阿爾卡特 (OT-927) 炭黑 聯(lián)通3G手機(jī) 雙卡雙待","sellPoint":"清倉(cāng)侠仇！僅北京轻姿，武漢倉(cāng)有貨！","price":29900000,"num":99999,"cid":560,"status":1,"created":1425821598000,"updated":1428755918000}

表示測(cè)試成功了逻炊！

恭喜你互亮！騷年，成功練成了SSM整合大法余素！
