需求背景:由于业务的增长，原有的表存放的太多的数据，每次去查询的数据耗时很久，严重影响了查询效率，所以才有了今天的博客文章，在处理问题的过程中，有考虑mysql的分区方案，我的分区是按照月份的，但是对于定时任务来说，时间存在重复的，所以mysql分区方案被剔除，因为项目xxl-job的方案，主要针对的表是xxl_job_log，但是改变涉及的位置比较多，手动去修改，一个是比较麻烦，二是容易出现测试测漏掉的情况发生，所以引入了mybatis的拦截器Interceptor，整体方案比较简单，但是因为存在同一个时间，很多任务都会同时执行的问题，所以会有并发比较高的问题
使用的数据库：mysql
使用的java的持久层框架: mybatis

* XxlJob开发示例（Bean模式）
*
* 开发步骤：
* 1、任务开发：在Spring Bean实例中，开发Job方法；
* 2、注解配置：为Job方法添加注解 "@XxlJob(value="自定义jobhandler名称", init = "JobHandler初始化方法", destroy = "JobHandler销毁方法")"，注解value值对应的是调度中心新建任务的JobHandler属性的值。
* 3、执行日志：需要通过 "XxlJobHelper.log" 打印执行日志；
* 4、任务结果：默认任务结果为 "成功" 状态，不需要主动设置；如有诉求，比如设置任务结果为失败，可以通过 "XxlJobHelper.handleFail/handleSuccess" 自主设置任务结果；
