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

装置调度核心

部署我的项目 

java -jar xxx &

http://localhost:8080/xxl-job-admin

账号：明码 admin/123456

开发本人的工作

官网有具体的教程

分布式任务调度平台 XXL-JOB

依赖 

compile group: 'com.xuxueli', name: 'xxl-job-core'

配置 

### xxl-job admin address list, such as "http://address" or "http://address01,http://address02"
xxl.job.admin.addresses=http://127.0.0.1:18301/xxl-job-admin

### xxl-job, access token
xxl.job.accessToken=

### xxl-job executor appname
xxl.job.executor.appname=pension-job
### xxl-job executor registry-address: default use address to registry , otherwise use ip:port if address is null
xxl.job.executor.address=
### xxl-job executor server-info
xxl.job.executor.ip=
xxl.job.executor.port=9999
### xxl-job executor log-path
xxl.job.executor.logpath=/data/applogs/xxl-job/jobhandler
### xxl-job executor log-retention-days
xxl.job.executor.logretentiondays=30

/**
 * 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；*
