2，dingshi定時類
import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import java.text.SimpleDateFormat;
import java.util.Date;
/**
* quartz示例定時器類
* Created by Administrator on 2017/9/25 0025.
*/
public class QuartzJobExample implements Job{
@Override
public void execute(JobExecutionContext arg0) throws JobExecutionException {
System.out.println(new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(new Date()) + "");
}
}
3，test類

import org.junit.runner.RunWith;
import org.quartz.Scheduler;
import org.quartz.SchedulerFactory;
import org.quartz.impl.StdSchedulerFactory;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
/**
* Created by yinx on 2017/9/25 0025.
*/
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "classpath:META-INF/test-config.xml" })
public class QuartzTest {
@Test
public void quartzTest(){
System.out.println("========================" + QuartzTest.class);
}
@Test
public void quartz() {
try {
SchedulerFactory gSchedulerFactory = new StdSchedulerFactory();
Scheduler sche = gSchedulerFactory.getScheduler();
String job_name = "動態任務調度";
System.out.println("【係統啟動】開始(每1秒輸出一次)...");
QuartzManager.addJob(sche, job_name, QuartzJobExample.class, "0/1 * * * * ?");
Thread.sleep(3000);
System.out.println("【修改時間】開始(每2秒輸出一次)...");

Thread.sleep(4000);
System.out.println("【移除定時】開始...");
