eventinfo.setEventid(moreeventinfo.getEventid());
eventinfo.setCitycode(moreeventinfo.getCitycode());
....................
getHibernateTemplate().update(eventinfo);
请各位高手帮帮忙,我建立映射表关联是为了在save的时候用,现在我只update  eventinfo这个表的时候怎么才能让eventdate表不update

Answer 1

 <set name="eventdate"  inverse="false"  cascade="all" lazy="false">
            <key>
                <column name="EVENTID" length="36" not-null="true"/>
            </key>
            <one-to-many class="com.palmcity.model.Eventdate" />
</set>
把all换成refesh试试

Answer 2

你这个问题没遇到过，但是cascade="all"肯定两边都会更新！

Answer 3

可是我更新时为什么eventdate表中数据只更新了一条,其它数据不更新,和eventinfo表中数据属于一对多eventdate关系,更新代码如下 public void saveAuditEventInfo(EventInfoVo moreeventinfo) {
// TODO Auto-generated method stub
Eventinfo info = new Eventinfo();
info.setEventid(moreeventinfo.getEventid());
info.setCitycode(moreeventinfo.getCitycode());
info.setType(moreeventinfo.getType());
info.setTitle(moreeventinfo.getTitle());
info.setEventstype(moreeventinfo.getEventstype());
info.setContent(moreeventinfo.getContent());
info.setStuation(moreeventinfo.getSituation());
info.setSourceaddress(moreeventinfo.getSituation());
info.setShorttitle(moreeventinfo.getShorttitle());
info.setDeletelabel(new BigDecimal(1));
info.setEventsource(moreeventinfo.getEventsource());
info.setAudittype(moreeventinfo.getAudittype());
info.setIscritical(moreeventinfo.getIscritical());
info.setHarmonychar(moreeventinfo.getHarmonychar());
info.setAuditdate(new Date());
info.setAuditopinion(moreeventinfo.getAuditopinion());
info.setAudituserid(moreeventinfo.getAudituserid());
info.setUserid(moreeventinfo.getUserid());
info.setPid(moreeventinfo.getPid());
Set dates = new HashSet();
Eventdate infodate = new Eventdate();
for (int i=0;i<moreeventinfo.getStarttimes().size();i++) {
infodate.setEnddate(moreeventinfo.getEnddate());
infodate.setStartdate(moreeventinfo.getStartdate());
if (moreeventinfo.getEweek() == null
|| moreeventinfo.getEweek().equals("")) {
infodate.setEweek("WA");
} else {
infodate.setEweek(moreeventinfo.getEweek());
}
infodate.setUpdatedatetime(new Date());
infodate.setStarttime(moreeventinfo.getStarttimes().get(i));
infodate.setEndtime(moreeventinfo.getEndtimes().get(i));
System.out.println(moreeventinfo.getStarttimes());
infodate.setEventid(new BigDecimal(moreeventinfo.getEventid()));
dates.add(infodate);
break;
}
dates.add(infodate);
info.setEventdate(dates);
dao.updateEventInfo(info);
}
