1.使用xml配置方式
Maven依赖
<properties>

Job类
package cn.enjoyedu.quartz.xml;
public class CronJob {
public void execute(){
System.out.println("定时任务执行...每5秒执行一次");
}
}
测试类
package cn.enjoyedu.quartz.xml;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class SpringQuartzXmlTest {
public static void main(String[] args) {
//启动spring容器
ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("classpath:application.xml");
System.out.println("initContext successfully");
}
}
执行结果
initContext successfully
定时任务执行...每5秒执行一次
定时任务执行...每5秒执行一次2.注解方式
application.xml
<!-- 开启组件扫描 -->
<context:component-scan base-package="cn.enjoyedu.quartz.annotation"></context:component-scan>
<!-- 开启定时任务，spring的定时任务。不是原生quartz -->
<task:annotation-driven/>Job class
package cn.enjoyedu.quartz.annotation;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;
@Component
public class AnnotationJob {
@Scheduled(cron = "0/5 * * * * ?")
public void excute(){
System.out.println("AnnotationJob 执行 5秒1次");
}
}执行结果
initContext successfully
AnnotationJob 执行 5秒1次
AnnotationJob 执行 5秒1次3.支持数据库配置cron表达式
3.1TimetaskController
@RequestMapping(value = "/initJob", method = RequestMethod.POST)
@ResponseBody
public String initJob() {
try {
ObjectResult result = timetaskBiz.initJob();
return JSONHelper.toJsonDataAPI(result, result.getApiStatus(), result.getErrorMsg());
} catch (Exception e) {
return JSONHelper.toJsonErrorDataAPI(e);
}
}
3.2 初始化job和启动job
/**
* 初始化job
* @param timetask
*/
@Override
public ObjectResult initJob() {
ObjectResult result = new ObjectResult();
try {
Scheduler scheduler = factoryBean.getScheduler();
//这里从数据库中获取任务信息数据
Timetask timetask = new Timetask();
//0 表示定时任务停止中 1 表示定时任务执行中
timetask.setJobStatus("0");
//从数据库中查询定时印务记录。
List<Timetask> timetaskList = this.getTimetaskListCus(timetask).getListTimetask();
for (Timetask task : timetaskList) {
addJob(task);
}
} catch (SchedulerException e) {
e.printStackTrace();
result.setErrorMsg(e.getMessage());
result.setApiStatus(ApiData.STATUS_EXCEPTION);
}
return result;
}
/**
* 添加job
* @param timetask
*/
private void addJob(Timetask timetask) {
if(timetask == null || (timetask.getJobStatus() == ScheduleJob.STATUS_RUNNING)) {
return;
}
try {
Scheduler scheduler = factoryBean.getScheduler();
TriggerKey triggerKey = TriggerKey.triggerKey(timetask.getName(),timetask.getGroupName());
CronTrigger cronTrigger = (CronTrigger) scheduler.getTrigger(triggerKey);
//如果不存在cronTrigger则重新创建一个
if(null == cronTrigger){
Class clazz = null;
try {
clazz = Class.forName(timetask.getBeanClass());
} catch (ClassNotFoundException e) {
e.printStackTrace();
}
JobDetail jobDetail = JobBuilder.newJob(clazz)
.withIdentity(timetask.getName(),timetask.getGroupName())
.usingJobData("data","")
.build();
jobDetail.getJobDataMap().put("scheduleJob",timetask);
CronScheduleBuilder cronScheduleBuilder = CronScheduleBuilder.cronSchedule(timetask.getCron());
cronTrigger = TriggerBuilder.newTrigger().withDescription(timetask.getIdStr())
.withIdentity(timetask.getName(),timetask.getGroupName())
.withSchedule(cronScheduleBuilder)
.build();
scheduler.scheduleJob(jobDetail,cronTrigger);
} else {
CronScheduleBuilder cronScheduleBuilder = CronScheduleBuilder.cronSchedule(timetask.getCron());
//TODO usingJobData的参数
cronTrigger = cronTrigger.getTriggerBuilder().withIdentity(triggerKey).usingJobData("data","")
.withSchedule(cronScheduleBuilder).build();
scheduler.rescheduleJob(triggerKey,cronTrigger);
}
//执行
scheduler.start();
} catch (SchedulerException e) {
e.printStackTrace();
}
3.3 job类
package com.zt.uni.api.task.jobs;
import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
public class MyJob implements Job {
@Override
public void execute(JobExecutionContext context) throws JobExecutionException {
System.out.println("MyJob ... execute ...");
}
}
package com.zt.uni.api.task.jobs;
import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
public class MyJob2 implements Job {
@Override
public void execute(JobExecutionContext context) throws JobExecutionException {
System.out.println("MyJob2 ... execute ...");
}
}
3.4 数据库配置
3.5 执行结果
MyJob ... execute ...
MyJob2 ... execute ...
MyJob ... execute ...
MyJob ... execute ...
MyJob2 ... execute ...
MyJob ... execute ...
MyJob ... execute ...3.6 存在的问题（最近工作忙，后面再补回来）
- 如果要支持定时任务可以拔插式使用
- 要支持图形界面配置
- 要支持定时任务在某个时间段期间执行[start_time ,end_time]执行
- 要支持记录定时任务的异常信息
