[绝痕]

AccountServiceImpl类

@Service("accountService")
@Transactional
public class AccountServiceImpl implements AccountService {

    @Autowired
    private AccountMapper accountMapper;

    @Override
    public Account getAccount(String cardNo) {
        System.out.println(cardNo);
        return accountMapper.getAccount(cardNo);
    }

    @Override
    public int updateAccount(Account account) {
        return 0;

接口使用单独Bean 注入无任何问题，使用扫描包注入就会出错，求大神解答

包目录结构是怎么样的？

[绝痕]

code.org.code.org.mason.mapper 已经找到了，确实是我包目录写错了：code.org.code.org.mason.mapper 多写了一层code.org 原包结构 code.org.mason.mapper 但是IDEA的报错依然没有解决，虽然项目运行也不会错
