Quartz+Spring Boot实现动态管理定时任务

2023-09-08 08:01:06 70
项目实践过程中碰到一个动态管理定时任务的需求：针对每个人员进行信息的定时更新，具体更新时间可随时调整、启动、暂定等。
思路
将每个人员信息的定时配置保存到数据库中，这样实现了任务的动态展示和管理。任务的每一次新增或变更，都会去数据库变更信息。
设置一个统一的任务管理器，专门负责动态任务的增删改查。

@ResponseBody
publicStringstart(@RequestParam(name="id",defaultValue="")Stringid){

可以看出，AAA的间隔时间时5s,BBB的间隔时间时2s.
到这里我们的测试已经一本完成了，接下来就是针对任务的更新，停止和启动了，只需要调用QuartzManager对应的方法即可，必要时更新一下数据库就好啦。
