SpringBoot搭配Quartz实现动态定时任务
前面2篇文章讲述了如何实现简单的定时任务，不过由于执行周期是写在配置文件里的，如果想要修改周期或者暂停任务都是比较麻烦的事情，那么能不能在不修改代码和暂停服务的情况下动态修改定时任务周期或者手动暂停任务？
通过Quartz是可以实现这一目标的，本文参考了GitHub上的文章，写了个动态定时任务的demo，特此记录。

application.yml配置（只列出跟quartz有关的）：
spring:
quartz:
job-store-type: jdbc
# 是否等待任务执行完毕后，容器才会关闭
wait-for-jobs-to-complete-on-shutdown: true
scheduler-name: SpringBootDemoScheduler
properties:
org:
quartz:
threadPool:
# 线程数量
threadCount: 5
# 线程优先级
threadPriority: 5
# 线程池中线程名称的前缀
threadNamePrefix: test-thread
# 加载任务代码的ClassLoader是否从外部继承
threadsInheritContextClassLoaderOfInitializingThread: true
jobStore:
# 最大能忍受的触发超时时间，如果超时则认为“失误”
misfireThreshold: 5000
# 选择JDBC的存储方式
class: org.quartz.impl.jdbcjobstore.JobStoreTX
# 类似于Hibernate的dialect，用于处理DB之间的差异，StdJDBCDelegate能满足大部分的DB（授权）
driverDelegateClass: org.quartz.impl.jdbcjobstore.StdJDBCDelegate
# 在调度流程的第一步，也就是拉取待即将触发的triggers时，是上锁的状态，即不会同时存在多个线程拉取到相同的trigger的情况，也就避免的重复调度的危险。参考：https://segmentfault.com/a/1190000015492260
acquireTriggersWithinLock: true另外，搭配Quartz需要事先创建相关的数据库表：
#
# In your Quartz properties file, you'll need to set
# org.quartz.jobStore.driverDelegateClass = org.quartz.impl.jdbcjobstore.StdJDBCDelegate
#
#
# By: Ron Cordell - roncordell
# I didn't see this anywhere, so I thought I'd post it here. This is the script from Quartz to create the tables in a MySQL database, modified to use INNODB instead of MYISAM.
