## 问题描述 ##

首先这个项目是存在定时器的，然后看似是定时任务报错导致的项目启动不起来，其实不然。

    Exception in thread "Quartz Scheduler [schedulerFactoryBean]" org.springframework.scheduling.SchedulingException: Could not start Quartz Scheduler after delay; nested exception is org.quartz.SchedulerException: The Scheduler cannot be restarted after shutdown() has been called.

## 解决过程 ##

在刚开始的时候一直是以为定时任务导致的项目启动不起来，却忽略了上面报错日志。搜了很多关于定时器报错的问题，都没有解决。然后往上一翻原来是有别的报错。就是Mybatis的映射文件resultMap填错了。改完之后就好了。

## 总结 ##

在遇到报错的时候，一定要沉着冷静，好好观察日志。再观察完日志之后，才能快速的锁定报错原因。
