更新之后，创建时间不见了，问题出现在哪里？老师在视频里把设置创建时间给去掉了
public void update(ClaimVoucher claimVoucher, List<ClaimVoucherItem> items) {
claimVoucher.setNextDealSn(claimVoucher.getCreateSn());
claimVoucher.setStatus(Constant.CLAIMVOUCHER_CREATED);
claimVoucherDao.update(claimVoucher);
List<ClaimVoucherItem> olds=claimVoucherItemDao.selectByClaimVoucher(claimVoucher.getId());
for(ClaimVoucherItem old:olds){
boolean isHave=false;
for(ClaimVoucherItem item:items){
if(old.getId()==item.getId()){
isHave=true;
break;
}
}
if(!isHave){
claimVoucherItemDao.delete(old.getId());
}
}
for(ClaimVoucherItem item:items){
item.setClaimVoucherId(claimVoucher.getId());
if(item.getId()!=null&&item.getId()>0){
claimVoucherItemDao.update(item);
}else{
claimVoucherItemDao.insert(item);
}
}
}//去更新
@RequestMapping("/to_update")
public String toUpdate(int id,Map<String,Object> map){
map.put("items", Constant.getItems());
ClaimVoucherInfo info=new ClaimVoucherInfo();
info.setClaimVoucher(claimVoucherBiz.get(id));
info.setItems(claimVoucherBiz.getItems(id));
map.put("info",info);
return "claim_voucher_update";
}
//更新
@RequestMapping("/update")
public String update(HttpSession session,ClaimVoucherInfo info){
Employee employee=(Employee)session.getAttribute("employee");
info.getClaimVoucher().setCreateSn(employee.getSn());
claimVoucherBiz.update(info.getClaimVoucher(),info.getItems());
return "redirect:deal";
