需求：返回对象的id为32位，每次查询的数据固定；displayRedDot  设置参数为0,1间隔显示，时间固定

一、通过for循环实现返回多条对象需求

public List<MessageContainerVO> findAllMessage()  {

List<MessageContainerVO> messageVOList = new ArrayList<MessageContainerVO>();  // achieve now time DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");// 设定格式 String formatTime = "2019-03-01 10:12:12"; Date timeDate = dateFormat.parse(formatTime);// Date类型 Timestamp dateTime = new Timestamp(timeDate.getTime());   for (int i = 10; i < 30; i++) { MessageContainerVO messageVO = new MessageContainerVO(); messageVO.setMessageContainerId("0248d87626aa44adab44794de349e4"+i); messageVO.setNewContentTips("最新系统消息" + i); messageVO.setNewMessageTime(dateTime); messageVO.setOrder(1); messageVO.setType(1); messageVO.setPicURL(url); messageVO.setTitle("系统消息：" + i); messageVO.setDisplayRedDot(i%2);   messageVOList.add(messageVO); } return messageVOList; }   }
