项目中应用

@HasPermisssion("monitor:job:add")
@OperLog(title = "定时任务",businessType = BusinussType.INSERT)
@PostMapping("save")
public R add(@RequestBody Job job) throws SchedulerException,TaskException{
	
	if(!CronUtils.isValid(job.getCronExpression())){
		return R.error("cron表达式不正确");
	}
	ValidatorUtils.validateEntity(job); //对传入的对象进行校验
	job.setCreateBy(getLoginName());
	return toAjax(jobService.insertJob(job));
}
