需求： 需要在页面设定某个时间，然后点击按钮后，执行某个调度，并且可以在页面删除某个调度
1、导包
<dependency>
<groupId>org.quartz-scheduler</groupId>
<artifactId>quartz</artifactId>
<version>2.2.1</version>
</dependency>
<dependency>
<groupId>org.quartz-scheduler</groupId>
<artifactId>quartz-jobs</artifactId>
<version>2.2.1</version>
</dependency>2、创建QuartzManager类，管理job
import org.apache.commons.lang.StringUtils;
import org.quartz.CronScheduleBuilder;
import org.quartz.CronTrigger;
import org.quartz.JobBuilder;
import org.quartz.JobDetail;
import org.quartz.JobKey;
import org.quartz.Scheduler;
import org.quartz.Trigger;
import org.quartz.TriggerBuilder;
import org.quartz.TriggerKey;
public class QuartzManager {
private Scheduler scheduler;
/**
* @Description: 添加一个定时任务
*
* @param jobName
* 任务名
* @param jobGroupName
* 任务组名
* @param triggerName
* 触发器名
* @param triggerGroupName
* 触发器组名
* @param jobClass
* 任务
* @param cron
* 时间设置，参考quartz说明文档
*/
@SuppressWarnings({ "unchecked", "rawtypes" })
public void addJob(String jobName, String jobGroupName, String triggerName, String triggerGroupName, Class jobClass,
String cron) {
try {
// 任务名，任务组，任务执行类
JobDetail jobDetail = JobBuilder.newJob(jobClass).withIdentity(jobName, jobGroupName).build();
// 触发器
TriggerBuilder<Trigger> triggerBuilder = TriggerBuilder.newTrigger();
// 触发器名,触发器组
triggerBuilder.withIdentity(triggerName, triggerGroupName);
triggerBuilder.startNow();
// 触发器时间设定
triggerBuilder.withSchedule(CronScheduleBuilder.cronSchedule(cron));
// 创建Trigger对象
CronTrigger trigger = (CronTrigger) triggerBuilder.build();
// 调度容器设置JobDetail和Trigger
scheduler.scheduleJob(jobDetail, trigger);
// 启动
if (!scheduler.isShutdown()) {
scheduler.start();
}
} catch (Exception e) {
throw new RuntimeException(e);
}
}
/**
* @Description: 修改一个任务的触发时间
*
* @param jobName
* @param jobGroupName
* @param triggerName
* 触发器名
* @param triggerGroupName
* 触发器组名
* @param cron
* 时间设置，参考quartz说明文档
*/
public void modifyJobTime(String jobName, String jobGroupName, String triggerName, String triggerGroupName,
String cron) {
try {
TriggerKey triggerKey = TriggerKey.triggerKey(triggerName, triggerGroupName);
CronTrigger trigger = (CronTrigger) scheduler.getTrigger(triggerKey);
if (trigger == null) {
return;
}
String oldTime = trigger.getCronExpression();
if (!oldTime.equalsIgnoreCase(cron)) {
/** 方式一 ：调用 rescheduleJob 开始 */
// 触发器
TriggerBuilder<Trigger> triggerBuilder = TriggerBuilder.newTrigger();
// 触发器名,触发器组
triggerBuilder.withIdentity(triggerName, triggerGroupName);
triggerBuilder.startNow();
// 触发器时间设定
triggerBuilder.withSchedule(CronScheduleBuilder.cronSchedule(cron));
// 创建Trigger对象
trigger = (CronTrigger) triggerBuilder.build();
// 方式一 ：修改一个任务的触发时间
scheduler.rescheduleJob(triggerKey, trigger);
/** 方式一 ：调用 rescheduleJob 结束 */
/** 方式二：先删除，然后在创建一个新的Job */
// JobDetail jobDetail =
// scheduler.getJobDetail(JobKey.jobKey(jobName, jobGroupName));
// Class<? extends Job> jobClass = jobDetail.getJobClass();
// removeJob(jobName, jobGroupName, triggerName,
// triggerGroupName);
// addJob(jobName, jobGroupName, triggerName, triggerGroupName,
// jobClass, cron);
/** 方式二 ：先删除，然后在创建一个新的Job */
}
} catch (Exception e) {
throw new RuntimeException(e);
}
}
/**
* @Description: 移除一个任务
*
* @param jobName
* @param jobGroupName
* @param triggerName
* @param triggerGroupName
*/
public void removeJob(String jobName, String jobGroupName, String triggerName, String triggerGroupName) {
try {
TriggerKey triggerKey = TriggerKey.triggerKey(triggerName, triggerGroupName);
scheduler.pauseTrigger(triggerKey);// 停止触发器
scheduler.unscheduleJob(triggerKey);// 移除触发器
scheduler.deleteJob(JobKey.jobKey(jobName, jobGroupName));// 删除任务
} catch (Exception e) {
throw new RuntimeException(e);
}
}
/**
* @Description:启动所有定时任务
*/
public void startJobs() {
try {
scheduler.start();
} catch (Exception e) {
throw new RuntimeException(e);
}
}
/**
* @Description:关闭所有定时任务
*/
public void shutdownJobs() {
try {
if (!scheduler.isShutdown()) {
scheduler.shutdown();
}
} catch (Exception e) {
throw new RuntimeException(e);
}
}
public Scheduler getScheduler() {
return scheduler;
}
public void setScheduler(Scheduler scheduler) {
this.scheduler = scheduler;
}
public String transCron(String time){
String seconds = StringUtils.substringAfterLast(time, ":");
String minute = StringUtils.substringAfter(time, ":").substring(0, 2);
String hour = StringUtils.substringAfter(time, " ").substring(0, 2);
String day = StringUtils.substringAfterLast(time, "-").substring(0, 2);
String month = StringUtils.substringAfter(time, "-").substring(0, 2);
return seconds + " " + minute + " " + hour + " " + day + " " + month + " ?";
}
}3、MyJob类，实现自己的调度业务,该类必须实现Job接口
package cn.tisson.qoe.quartz;
import java.util.Map;
import javax.annotation.Resource;
import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import cn.tisson.qoe.utils.ApacheFtpUtil;
import cn.tisson.qoe.utils.CallShellUtil;
public class MyJob implements Job{
private Logger logger = LoggerFactory.getLogger(MyJob.class);
//直接注入
@Resource
private QuartzManager quartzManager;
@Override
public void execute(JobExecutionContext context) throws JobExecutionException {
try {
test();
downloadYZfile();
} catch (Exception e) {
e.printStackTrace();
}
}
public void test() throws Exception{
logger.info("【test】动态定时调度测试");
}
/**
* 同步光宽转化率月清单
* @throws Exception
*/
public void downloadYZfile() throws Exception{
//自己的业务逻辑在这里实现
}
}
4、在springmvc的配置文件，添加配置
<bean id="startQuartz" lazy-init="true" autowire="no" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
<property name="triggers">
<list>
<!-- <ref bean="cronTrigger" /> -->
</list>
</property>
</bean>
<bean id="quartzManager" class="cn.tisson.qoe.quartz.QuartzManager" lazy-init="false" init-method="startJobs" >
<!--这个对象一定要注入，这样类才能进行管理，还有在类型要用get set方法，不然会报错。-->
<property name="scheduler" ref="startQuartz" />
</bean> 5、在Controller中
//这个bean在spring中配置，可以直接注入
@Resource
private QuartzManager quartzManager;
@RequestMapping(value = "startQuartz", method = {RequestMethod.GET})
@ResponseBody
public String testQuartz(String quartzTime) throws Exception{
logger.info("===========开始执行调度=========时间为 " + quartzTime);
String cronStr = quartzManager.transCron(quartzTime);
logger.info("======cron表达式========" + cronStr);
quartzManager.addJob("test", "test", "test", "test", MyJob.class, cronStr);
//quartzManager.modifyJobTime("test", "test", "test", "test", "0 50 10 * * ?");
//quartzManager.removeJob("test", "test", "test", "test");
//quartzManager.shutdownJobs();
return "success";
}
@RequestMapping(value = "stopQuartz", method = {RequestMethod.GET})
@ResponseBody
public String shutDownQuartz() throws Exception{
logger.info("===========关闭调度test==================");
quartzManager.removeJob("test", "test", "test", "test");
return "关闭成功";
}因为需求是要配置时间执行调度，所以不能控制执行次数，如果需要控制执行次数，可以使用
triggerBuilder.withSchedule(SimpleScheduleBuilder.simpleSchedule().withIntervalInSeconds(1).withRepeatCount(1));//执行间隔和重复执行的次数
