java spring事务问题

这是我的spring的文件：

</beans>这是我要加事务的方法： @Transactional
public void insertUser(WingUser wingUser,Activity_bean aBean) throws Exception {
wingUser = new WingUser();
wingUser.setUserId(aBean.getUserId());
wingUser.setSt(aBean.getSt());
wingUser.setLoginNo(aBean.getLoginNo());
wingUser.setSno(null);
wingUserDAO.insert(wingUser);
WingUser wingUser2 = new WingUser();
wingUserDAO.insert(wingUser2);

}不知到为什么事务 没有加成功，第一个winguser还是能加上去。没有rollback；恳请各位大哥帮帮忙，解决下。
