Spring Quartz 基于数据库管理Job

Spring Quartz可以采用xml形式进行job管理，但此种形式无法动态管理job。

故，推荐采用DB来管理job，此种情况，可以进行动态配置job的执行时间，暂定、启动、删除job等操作。

下面是核心业务类：

import java.sql.SQLException;
import java.text.ParseException;
import java.util.List;
import java.util.Map;

import org.quartz.CronExpression;
import org.quartz.CronTrigger;
import org.quartz.JobDetail;
import org.quartz.Scheduler;
import org.quartz.SchedulerException;
import org.quartz.SchedulerFactory;
import org.quartz.impl.StdSchedulerFactory;

import com.hafx.codesure.batchjob.dao.impl.QuartzDaoImpl;

PS：使用这种作业的JDBC存储形式，可以充分发挥quartz的集群特性。

下载后，里面的quartz-xx.xx \ docs \ dbTables 里面有各种db的建表语句。
