hibernate乐观锁 StaleObjectStateException 疑惑10

我用的ssh2做的项目，事务是使用spring的事务代理代理的service层，也使用了hibernate的乐观锁，

结果问题出来了,hibernate乐观锁是在事务提交的时候抛出的异常，但是那个时候service层的方法已经执行完了，所以spring抓不到异常

那么事务也就无法回滚，实际上异常只能在action层抓到，不知道我的理解有没有问题,还请大神们解答。

附上代码

<bean class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator">  <property name="beanNames">  <list> <value>payorderService</value> </list>  </property> <property name="interceptorNames"> <list> <value>transactionInterceptor</value>  </list> </property> </bean>

payorderService代码:

if (grouptzorderlistByRaftDay != null && grouptzorderlistByRaftDay.size() > 0) {

grouptzorderlistByRaftDay = mergeDayRaft(grouptzorderlistByRaftDay);

for (int j = 0; j < grouptzorderlistByRaftDay.size(); j++) {// 日控制 zt = new TZorderlist(); zt = (TZorderlist) grouptzorderlistByRaftDay.get(j); payorderDao.updateDayControl(orid, zt.getDtstartdate().substring(0, 10), zt.getItickettypeid().toString(), zt .getId().getIscenicid().toString(), zt.getZnumb().intValue()); } }

payorderDao方法: public void updateDayControl(String orid, String date, String itickettypeid, String iscenicid, int numb) throws Exception { try { StringBuffer hql = new StringBuffer(); hql.append(" from Productcontrol where iscenicid=" + iscenicid + " and itickettypeid=" + itickettypeid + " and stdata='" + date + "' and controltype='02'"); List list = this.find(hql.toString()); Productcontrol p = null; if (list != null && list.size() > 0) { for (int j = 0; j < list.size(); j++) { p = (Productcontrol) list.get(j); p.setSoldnumber(p.getSoldnumber() + numb); this.update(p); } } } catch (Exception e) { System.out.println("=========>>hibernate 乐观锁引起事务异常"); e.printStackTrace(); throw e; } }

就是这个方法里面Productcontrol 对象含有vision字段但是在这里未抛出是否是在整个事务提交的时候，hibernate才去验证?

请打什么解答
