public interface UserMapper extends BaseMapper<User,Integer> {

 
    public  User  selectUserByName(String userName);


    public   Integer updateUserPwd(Integer userId,String userPwd);


}



public interface SaleChanceMapper extends BaseMapper<SaleChance,Integer> {

 
    public List<SaleChance>  querySaleChance(String customerName,String creatorName,Integer state);

}




public  class BaseService<T,ID> {

    @Resource
    private BaseMapper<T,ID> baseMapper;
}

@Service
public    class LoginService extends BaseService<User,Integer> {

        @Resource
    private UserMapper userMapper;
}

用的是接口代理方式实现dao

public class BaseService<T,ID> { //不能使用@Resource 否则Spring无法正确注入BaseMapper<T,ID> 无法识别 @Autowired private BaseMapper<T,ID> baseMapper;

同时给baseMapper类加上注解交给IOC 就好了是这个嵌套的内置注入发生了问题注解@Resource 无法识别
