一、背景
如果任务执行到一半突然宕机怎么办?能否重新执行任务?任务执行的数据能够以恢复吗?带着这些问题,我发现了几种持久化策略,先讲最简单,也是我们最为喜闻乐见的mysql吧!说干就干,我们来写一个最简单的吧。
二、代码实现
其实实现起来也很简单,主要步骤如下:
- 在数据库控制台执行如下sql脚本
#
# Quartz seems to work best with the driver mm.mysql-2.0.7-bin.jar
#
# PLEASE consider using mysql with innodb tables to avoid locking issues
#
# In your Quartz properties file, you'll need to set
# org.quartz.jobStore.driverDelegateClass = org.quartz.impl.jdbcjobstore.StdJDBCDelegate
#

- pom配置延用quartz(一)基础篇
- quartz.properties配置
# 存储类型有三种:1. 内存存储,org.quartz.simpl.RAMJobStore,性能最好,执行最快
# 2. 数据库存储,org.quartz.impl.jdbcjobstore.JobStoreTX,性能最差,但是能够持久化,可恢复等
# 3. TerracottaJobStore服务器,性能优于数据库一个数量级,性能居中,可持久化,可恢复

本文是基于quartz(二)动态增删改查停止启用job的基础上进行扩展的,有兴趣的可以去看看。
三、测试结果
1、通过接口创建一个job
- swagger执行接口调用
