我知道这个错误已经发生，因为找不到更新对象的会话。当我使用下面的代码时，我得到“会话已经关闭”
@RequestMapping(value = Route.ediBillingLogCreate,method = {RequestMethod.POST, RequestMethod.GET})
public @ResponseBody String updateEdiBillingLog(@ModelAttribute("SearchEntityObject")EdiBilling404LogIiss ediBilling404LogIiss, BindingResult result, SessionStatus status, HttpServletRequest req, HttpServletResponse response)
{
BigDecimal id=ediBilling404LogIiss.getEdiBilling404LogUid();
if(id!=null && id.intValue()>0){
ediBillingLogService.updateupdateEdiBillingLog(ediBilling404LogIiss);
}
return "success";
}
但是当我在另一个控制器中使用类似的代码时，我没有收到此错误。 对于Eg：
@RequestMapping(value = Route.nvoccShipperForwarderSave)
public @ResponseBody
String saveForwarderDetails(@ModelAttribute("BlForwarderParties") BlHousePartiesIiss blHousePartiesIiss ,BindingResult result, SessionStatus status,@RequestParam String blNumber,@RequestParam long partyId, @RequestParam String blHouseUid) throws Exception {
if (result.hasErrors()) {
LOG.info("Errors" + result.toString());
}
Long id=null;
if(partyId==0){
id=nvoccBlHouseService.saveNewRecord(blHousePartiesIiss);
}
else
{
BlHousePartiesIiss idOld=nvoccBlHouseService.updatePartiesDetails(blHousePartiesIiss);
id=idOld.getHousePartyId();
}
return "success";
}

// updateEdiBillingLog
public void updateupdateEdiBillingLog(

try{
ediBillingLogDAO.update(ediBilling404LogIiss);
}
catch(Exception e)
{
e.printStackTrace();
}
}
Which in turn Calls below method
@Transactional
public T update(T object) {
sessionFactory.getCurrentSession().setFlushMode(FlushMode.AUTO);
sessionFactory.getCurrentSession().update(object);
try {
sessionFactory.getCurrentSession().flush();
} catch (HibernateException e) {
log.error(e.getMessage());
}
return object;
}
我想提醒您注意BlHousePartiesIiss和EdiBilling404LogIiss之间的区别。 BlHousePartiesIiss有一个主键。在EdiBilling404LogIiss中，键组合成为主键。
为什么行为存在差异？当我在两种情况下使用当前会话时。
