我已经下载了 Quartz,我正在尝试运行一个示例。
我有一个JDBCJobStore
无法使用的示例,但此示例可以正常使用RAMJobStore
.
就在我选择JDBCJobStore
并引发异常时。
我正在使用石英 1.6.5。
代码:
package test;
import org.quartz.JobDetail;
import org.quartz.Scheduler;
import org.quartz.SchedulerException;
import org.quartz.SchedulerFactory;
import org.quartz.SimpleTrigger;
import org.quartz.Trigger;
public class ReportRunner {
public static void main(String[] args) {
try {
SchedulerFactory schedFact = new org.quartz.impl.StdSchedulerFactory();
Scheduler sched = schedFact.getScheduler();
sched.start();
JobDetail jobDetail = null;
SimpleTrigger trigger2 = null;
jobDetail = new JobDetail("Income Report", "Report Generation",
QuartzReport.class);
jobDetail.getJobDataMap().put("type", "FULL");
jobDetail.setDurability(true);
trigger2 = new SimpleTrigger("Income Report", "Report Generation");
trigger2.setStartTime(new java.util.Date(
System.currentTimeMillis() + 4000));
trigger2.setRepeatInterval(5000);
trigger2.setRepeatCount(100);
sched.scheduleJob(jobDetail, trigger2);
} catch (Exception e) {
e.printStackTrace();
}
}
}
package test;
import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
public class QuartzReport implements Job {
public void execute(JobExecutionContext cntxt) throws JobExecutionException {
System.out.println("Generating report - "
+ cntxt.getJobDetail().getJobDataMap().get("type"));
}
}
配置文件:
org.quartz.scheduler.instanceName = Sched1
org.quartz.scheduler.instanceId = 1
org.quartz.scheduler.rmi.export = false
org.quartz.scheduler.rmi.proxy = false
org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool
org.quartz.threadPool.threadCount = 3
org.quartz.jobStore.class = org.quartz.impl.jdbcjobstore.JobStoreTX
org.quartz.jobStore.driverDelegateClass = org.quartz.impl.jdbcjobstore.StdJDBCDelegate
org.quartz.jobStore.tablePrefix = QRTZ_
org.quartz.jobStore.dataSource = myDS
org.quartz.dataSource.myDS.driver = com.mysql.jdbc.Driver
org.quartz.dataSource.myDS.URL = jdbc:mysql://192.168.0.4:3306/conference
org.quartz.dataSource.myDS.user = root
org.quartz.dataSource.myDS.password =root
org.quartz.dataSource.myDS.maxConnections 5
这是运行时显示的异常,已记录
