分布式任务调度平台XXL-JOB
初始化数据库
执行官网提供的SQL即可
/xxl-job/doc/db/tables_xxl_job.sql源码编译
xuxueli/xxl-job
下载好源码后，须要对局部配置进行批改
xxl-job-admin：调度核心xxl-job-core：公共依赖xxl-job-executor-samples：执行器Sample示例（抉择适合的版本执行器，可间接应用，也能够参考其并将现有我的项目革新成执行器） ：xxl-job-executor-sample-springboot：Springboot版本，通过Springboot治理执行器，举荐这种形式； ：xxl-job-executor-sample-frameless：无框架版本；因为是间接部署，所以只须要批改调度核心配置即可
