在学习spring事务的时候，我在Servcie类上或者类方法上加上@Transactional后，运行测试代码就会报错。不添加注解@Transactional时，就没有报错，在网上也没有收到关于这个报错的问题。所以想请教一下有没有人碰到过这种问题？
java.lang.NoSuchMethodError: org.springframework.core.KotlinDetector.isSuspendingFunction(Ljava/lang/reflect/Method;)Z
Service
@Service
@Transactional
public class UserService {
@Autowired
private UserDao userDao;
//转账的方法
public void accountMoney(){
//lucy少一百
userDao.reduceMoney();
//模拟异常
//int i = 10/0;
//Marry多一百
userDao.addMoney();
}
}
DaoImpl
@Repository
public class UserDaoImpl implements UserDao {
@Autowired
private JdbcTemplate jdbcTemplate;
//lucy转账100给marry
@Override
public void addMoney() {
String sql = "update t_account set account=account-? where username=?";
jdbcTemplate.update(sql,100,"lucy");
}
@Override
public void reduceMoney() {
String sql = "update t_account set account=account+? where username=?";
jdbcTemplate.update(sql,100,"Marry");
}
}
