下面这里代码中的所有变量都在for循环之外创建，对于对象的创建我还是有点不明白，如果按照下面的“（1）”的写法，如果list的集合中的数据超过1条数据，当for循环第二次进入系统时下面"(2)"中的do{}方法内，对象竟然取得的内容是重复的，不知道什么原因，最后我将“（1）”的方法修改成 先 new 对象，再给对象赋值，才把问题解决。在此记录一下for (int i =0;i<querySocialSecurityS.size();i++ ) {
					
	//处理同一张点单
	//判断下一条订单id是否与上一条数据id一致，不一致则循环下一张订单
	securityVo= querySocialSecurityS.get(i);// <span style="color:#FF0000;">（1）</span>
	
	tempSecurityVo= querySocialSecurityS.get(i);
	
	securityId=securityVo.getCesId();
	
	empSecurityId = String.valueOf(Helper.requestOID(CS_EMP_SECURITY).longValue());
	
	System.out.println("securityId=="+securityId);
	do{//<span style="color:#FF0000;">(2)</span>
		securityVo= querySocialSecurityS.get(i);						

		if(securityId.equals(securityVo.getCesId())){
			//把原办理记录对应的社保公积金办理明细赋给新的办理记录
			insertSecurityItemValues=new StringBuffer("");
