JSP

var y = 6;  //添加IDvar z = 1;//删除ID function warning(){  $.post("getBusWarn", function(data) {    $("#warning").prepend("<a id='warn"+y+"' class='t-overflow' href='####' onclick='highlight(this)'>"+data+"</a>"); $("#warn"+z).remove(); z++; y++;    setTimeout('warning()');    });  };window.onload=warning;

后台

@ResponseBody@RequestMapping(value = "getBusWarn")public String getBusWarn() {String dateString = busMonitorService.getBusWarn();return dateString;}

service

public String getBusWarn() {Date date = new Date();SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");String dateString = formatter.format(date);//查询无数据，睡几秒/*if (StringUtils.isBlank(dateString)) {try {Thread.sleep(1000 * 5);} catch (InterruptedException e) {e.printStackTrace();}}*/// 预警信息保存到本地// warningRecordService.save(warningRecord);//testtry {Thread.sleep(1000 * 3);} catch (InterruptedException e) {e.printStackTrace();}return dateString+"公交";}
