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
### xxl-job, datasource
spring.datasource.url=jdbc:mysql://localhost:3306/xxl_job?useUnicode=true&characterEncoding=UTF-8&autoReconnect=true&serverTimezone=Asia/Shanghai
spring.datasource.username=guest
spring.datasource.password=123456
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
### xxl-job, email
spring.mail.host=smtp.qq.com
spring.mail.port=25
spring.mail.username=njpkhuan@foxmail.com
spring.mail.password=yltkhbpxjeacbbfj
spring.mail.properties.mail.smtp.auth=true
spring.mail.properties.mail.smtp.starttls.enable=true
spring.mail.properties.mail.smtp.starttls.required=true
spring.mail.properties.mail.smtp.socketFactory.class=javax.net.ssl.SSLSocketFactory

/**
* XxlJob 开发示例（Bean 模式）* <p>
* 开发步骤：* 1、在 Spring Bean 实例中，开发 Job 办法，形式格局要求为 "public ReturnT<String> execute(String param)"
* 2、为 Job 办法增加注解 "@XxlJob(value=" 自定义 jobhandler 名称 ", init ="JobHandler 初始化办法 ", destroy ="JobHandler 销毁办法 ")"，注解 value 值对应的是调度核心新建工作的 JobHandler 属性的值。* 3、执行日志：须要通过 "XxlJobLogger.log" 打印执行日志；*
