Quartz储存方式之JDBC JobStoreTX：http://blog.csdn.net/uhzgnaw/article/details/46358333
Quartz的任务方式有两种，一种是RAM但这种方式，应用中断或重启任务易丢失，而RDB方式将任务执行情况及上下文保存到数据库，中断或重启可以重新执行。首先下载Quazrt发布包，解压，运行doc文件夹下（E:\Quartz\quartz-2.2.3\docs\dbTables）的tables_mysql_innodb.sql脚本,如果用Quartz的默认数据连接池，则需要夹C3po相关的依赖包，为什么是c3p0,可以查看一下这篇文章：

可以看到Quart将任务信息放在了job，trriger中，触发的任务放在fire_trriger中
屏蔽一下代码，重新启动程序

/*JobDetail job = JobBuilder.newJob(SimpleJob.class).withIdentity("SimpleJob", "Job-Group-Simple").build();

quartz.properties文件：
#线程池实现类
org.quartz.threadPool.class =org.quartz.simpl.SimpleThreadPool
#线程池数
org.quartz.threadPool.threadCount = 5
#线程池优先级
org.quartz.threadPool.threadPriority = 5
#线程池运行模式守后，还是前台
org.quartz.threadPool.makeThreadsDaemons=false
###线程池配置的继承属性
org.quartz.threadPool.threadsInheritGroupOfInitializingThread=true
org.quartz.threadPool.threadsInheritContextClassLoaderOfInitializingThread=true
###保存job调度执行信息到RAM，这种方式当应用下次重启时，job调度信息容易丢失
#org.quartz.jobStore.class = org.quartz.simpl.RAMJobStore
#org.quartz.jobStore.misfireThreshold = 60000
############.JobStoreTX，是将job调度信息保存到RDB中，应用重启时可以重新调度job
org.quartz.jobStore.class = org.quartz.impl.jdbcjobstore.JobStoreTX
org.quartz.jobStore.driverDelegateClass = org.quartz.impl.jdbcjobstore.StdJDBCDelegate
#表前缀
org.quartz.jobStore.tablePrefix = QRTZ_
org.quartz.jobStore.dataSource=test
#org.quartz.dataSource.test.connectionProvider.class=org.quartz.utils.PoolingConnectionProvider
org.quartz.dataSource.test.driver=com.mysql.jdbc.Driver
org.quartz.dataSource.test.URL=jdbc\:mysql\://localhost\:3306/test?useUnicode\=true&characterEncoding\=utf8&characterSetResults\=utf8
org.quartz.dataSource.test.user=root
org.quartz.dataSource.test.password=123456
org.quartz.dataSource.test.maxConnections=20
总结：
从以上分析可以看出，JobStoreTX-RDB方式，实际上，就是将job存储在 qrtz_job_details表中，将cron_triggers存储在qrtz_cron_triggers，而触发的任务存储在qrtz_fired_triggers表中，应用崩溃时，而已触发的任务保存在qrtz_fired_triggers，下次应用启动时，直接调度qrtz_fired_triggers表中的任务。
备注：其他相关表
qrtz_paused_trigger_grps：暂定触发任务表
qrtz_triggers：触发任务表
qrtz_simple_triggers：简单触发器表
qrtz_scheduler_state：调度状态表
来看一下qrtz_triggers：
mysql> select * from qrtz_triggers;
