XXL-JOB

分布式任务调度平台XXL-JOB

初始化数据库

执行官方提供的SQL即可
/xxl-job/doc/db/tables_xxl_job.sql

源码编译

xuxueli/xxl-job

下载好源码后,需要对部分配置进行修改

xxl-job-admin:调度中心
xxl-job-core:公共依赖
xxl-job-executor-samples:执行器Sample示例(选择合适的版本执行器,可直接使用,也可以参考其并将现有项目改造成执行器)
    :xxl-job-executor-sample-springboot:Springboot版本,通过Springboot管理执行器,推荐这种方式;
    :xxl-job-executor-sample-frameless:无框架版本;

因为是直接部署,所以只需要修改调度中心配置即可

### 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
[email protected]
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

官网有详细的教程

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
