标记一下（hibernate update无主键表失败）
试验了一下，对无主键表更新不能成功,添加删除没问题

应该是很标准的无主键表的配置了，担心其会调用equals方法来判断对象是否变化，就将它加上了，结果更新还是失败
SsSysIpFilter ssSysIpFilter = (SsSysIpFilter)list.get(0);
SsSysIpFilterId id = ssSysIpFilter.getId();id.setIpFrom(new_ipFrom);id.setIpTo(new_ipTo);id.setIpFromNumber(new_ipFromNumber);id.setIpToNumber(new_ipToNumber);id.setIpFilteType(ipFilteType_new);hibernateTemplate.update(ssSysIpFilter);?
只能看到select语句，根本看不到update语句出来，估计hibernate无法判断无主键表的信息是否发生了变化.
?
public void deleteSsSysIpFilter(String ipFrom ,String ipTo){List list = hibernateTemplate.find("from SsSysIpFilter s where s.id.ipFrom = '"+ipFrom+"' and s.id.ipTo ='"+ipTo+"'");if(list.size()>0){hibernateTemplate.delete((SsSysIpFilter)list.get(0));}}public void addSsSysIpFilter(SsSysIpFilter ipFilter){hibernateTemplate.save(ipFilter);}添加删除都没问题??
