关于quartz cron表达式饭解析验证输出实现部分截图代码

Controller层 

@ResponseBody
@RequestMapping(value = "/parseCronExpression", method = RequestMethod.POST, produces = MediaType.APPLICATION_JSON_VALUE)
public IErrorCode parseCronExpression(String expression) throws ParseException {
CronExpression cron = new CronExpression(expression);
if (!cron.isValidExpression(expression))
return SysErrorCode.PLANTASK_PARSE_FAIL;


List<String> dateList = new ArrayList<String>();
Date lastRun = DateUtil.getCurrentDate();
for (int i = 0; i < 3; i++) {
lastRun = cron.getNextValidTimeAfter(lastRun);
String str = DateUtil.convertDate2String(lastRun,DateUtil.LONG_DATE_FORMAT);
dateList.add(str);
}
return new Result(Base.SUCCESS, dateList);
}

View 层

  //泛解析显示cron任务表达式执行三次示例  
$('#btnFan').click(function(){
 $.post(parseUrl,{expression:$('#expression').val()},function(r){
        if(pm.result.isSuccess(r)){
result = r.attr;
var html = [];
$.each(result,function(i,v){
html.push("第"+(i+1)+"次触发时间："+v);
});
$("#examples").html(html.join("<br>"));
}
        else{
var info = "表达式格式异常，请重新设置！";
$("#examples").html(info);
alert(info);
} 
        });          
 });
