在使用持久化框架Hibernate的時候，有時候會用到級聯儲存： 儲存主表記錄的同時將子表記錄一併儲存的方法通常叫級聯儲存

 java程式碼參考

//新增記錄到基表,同時新增記錄到歷史表及聯儲存
				//基物件封裝
				agentFile = new TAgentFile();
				agentFile.setAgentCode(agentNO);
				agentFile.setName(fileName);
				agentFile.setStatus(baseStatus);
				//歷史表物件封裝
				Long hisStatus = null;          //歷史子表狀態
				HashSet<TAgentFileHistory> agentFileHistorys = new HashSet<TAgentFileHistory>();
				TAgentFileHistory  agentFileHistory = new TAgentFileHistory();
				if("add".equals(fileStatus)){
					hisStatus = 1L;
					agentFileHistory.setOldSize(null);
					agentFileHistory.setOldTime(null);
					agentFileHistory.setNewSize(Long.valueOf(newSize));
					agentFileHistory.setNewTime(DateUtils.parseDate(newTime, "yyyyMMddhhmmss"));
				}else if("update".equals(fileStatus)){
					hisStatus = 2L;
					agentFileHistory.setOldSize(Long.valueOf(oldSize));
					agentFileHistory.setOldTime(DateUtils.parseDate(oldTime, "yyyyMMddhhmmss"));
					agentFileHistory.setNewSize(Long.valueOf(newSize));
					agentFileHistory.setNewTime(DateUtils.parseDate(newTime, "yyyyMMddhhmmss"));
				}else {
					hisStatus = 3L;
					agentFileHistory.setOldSize(Long.valueOf(oldSize));
					agentFileHistory.setOldTime(DateUtils.parseDate(oldTime, "yyyyMMddhhmmss"));
					agentFileHistory.setNewSize(null);
					agentFileHistory.setNewTime(null);
				}
				agentFileHistory.setStatus(hisStatus);
				agentFileHistory.setCreatedTime(new Date());
				agentFileHistory.setTAgentFile(agentFile);
				
				agentFileHistorys.add(agentFileHistory);
				
				agentFile.setTAgentFileHistories(agentFileHistorys);
				hibernateDao.insert(agentFile);
 

hibernate配置檔案 TAgentFile.hbm.xml

關鍵程式碼是cascade="all"  即是配置了級聯儲存的屬性
