# SpringMVC + Spring +mybatis工程

一、dispatcher-servlet.xml配置

二、applicationContext.xml配置

三、Controller 类

@Controller
@RequestMapping("/api")
public class TestController {
    private static Logger logger = Logger.getLogger(ShopController.class);
    @Autowired
    TestService testService; //需要调用Spring逻辑服务类
    @RequestMapping(value="/login.do",method = RequestMethod.POST)
    public void login(HttpServletRequest request, HttpServletResponse response) {
    }
}

四、Service类

//定义Sevice接口
public interface TestService {
    String login(HttpServletRequest request, String userName, String password);
}

//定义ServiceImpl实现类型
@Service("ShopService")
public class TestServiceImpl implements ShopService{
  
    @Autowired
    TestDao testDao; //mybatis 持久化服务接口
    @Override
    public String login(HttpServletRequest request, String userName, String password)  {
        
    }

五、myBatis持久化服务接口

@Repository
public interface TestDao {
    //查询语句
   @Select("select Top 1 * from Face_Register where telNo=#{telNo}")
    Face_Register getByTelephone(String telNo);
    
    //存储过程
    @Select("{call dbo.Page(" +
            "#{map.out_PageCount,mode=OUT,jdbcType=INTEGER},"+ //总页数输出
            "#{map.out_ResultCount,mode=OUT,jdbcType=INTEGER},"+ //总记录数输出
            "#{map.out_SQL,mode=OUT,jdbcType=NVARCHAR},"  + //返回数据库SQL查询语句
            "#{map.in_Table,mode=IN,jdbcType=NVARCHAR},"+ //查询表名
            "#{map.in_Key,mode=IN,jdbcType=VARCHAR}," + //主键
            "#{map.in_Fields,mode=IN,jdbcType=NVARCHAR}," + //查询字段
            "#{map.in_Where,mode=IN,jdbcType=NVARCHAR}," + //查询条件
            "#{map.in_Order,mode=IN,jdbcType=NVARCHAR}," + //排序字段
            "#{map.in_Begin,mode=IN,jdbcType=INTEGER}," + //开始位置
            "#{map.in_PageIndex,mode=IN,jdbcType=INTEGER}," + //当前页数
            "#{map.in_PageSize,mode=IN,jdbcType=INTEGER})}") //页大小
    @Options(statementType= StatementType.CALLABLE)
    List getByAttrs(@Param("map") Map map);
    
    //插入语句
    @Insert("insert into Face_Register(name,openId,telNo,applyTime,state,imgUrl,cardNo) " +"values(#{faceRegister.name},#{faceRegister.openId},#{faceRegister.telNo},getDate(),#{faceRegister.state}," +"#{faceRegister.imgUrl},#{faceRegister.cardNo})")
    long add(@Param("faceRegister") Face_Register faceRegister);
    
    //修改语句
    @Update("update Face_Register set state=#{state} where id=#{id} and state<>2")
    long approve(@Param("id") int id,@Param("state") int state);
}
