测试的方法
@Transactional
public void addUser() {

User user = hibernateTemplate.get(User.class, 1);

user.setUserName("bbba");
hibernateTemplate.update(user);

User user1 = new User();
user1.setPassword("aa");
user1.setUserName("aaa");
hibernateTemplate.save( user1);

throw new RuntimeException();
}

为什么只有update方法回滚了，save方法没有回滚，数据库里update没有起作用，save起作用了
