SpringBoot零基础集成xxl-jobxxl-job-admin部署部署SpringBoot示例xxl-job-executor-sample-springboot分析执行日志原理
示例程序中的代码位置@XxlJob注解的使用 总结
SpringBoot零基础集成xxl-jobxxl-job主要分成两部分:
一部分是xxl-job-admin。这是管理控制台，简单理解就是用于管理和调度任务。另一部分是xxl-job-core。这主要是帮助开发人员更高效的开发具体的任务，然后与调度中心交互，完成具体任务的执行操作。 xxl-job-admin部署
xxl-job源码地址https://github.com/xuxueli/xxl-job
下载源码
git clone https://github.com/xuxueli/xxl-job 执行数据库初始化脚本tables_xxl_job.sql
修改配置文件tables_xxl_job.sql
修改xxl-job-admin启动端口
修改数据库配置信息
关闭邮件通知服务

查看本机IP
配置执行器
在调度中心界面调度执行一次任务
查看执行日志
分析执行日志原理
从上面的执行日志中可以看到输出XXL-JOB, Hello World等内容，这是怎么输出到调度中心的呢？接着往下看。
示例程序中的代码位置
使用XxlJobHelper.log()这个方法可以把日志输出到调度中心，如果使用本地的slf4j输出日志则只能打印到本地，要注意这个区别。
示例源码@XxlJob("demoJobHandler")中的demoJobHandler要与调度中心的配置JobHandler保持一致
每个步骤都有截图，写的很详细，方便零基础的同学跟着节奏一步一步上手。有兴趣的同学可以模仿这个示例程序自己写一个JobHandler，然后在调度中心注册一个执行器，新增一个任务。如果有疑问，欢迎交流沟通。
