Spring整合Quartz实现动态定时器

一 : 首先了解spring定时器所使用到的场景

比如 : 定时统计报表,或者登录账户密码验证失败冻结账户后,每晚12点将账户解锁等等...

使用jar包 : 2.0使用方法不同

<!-- 定时器 -->
<dependency>
<groupId>org.quartz-scheduler</groupId>
<artifactId>quartz</artifactId>
<version>1.8.6</version>
</dependency>

2. 代码示例
1. 定义被执行的任务类
package com.jk.controller;

import java.text.SimpleDateFormat;
import java.util.Date;

import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
// 准备定时调度的任务 工作类
public class TestDing implements Job {

@Override
public void execute(JobExecutionContext arg0)
throws JobExecutionException {

System.out.println(new
SimpleDateFormat("yyyy-MM-dd").format(new Date())+"-
=-=-=-=-=");

}
}

2. 通过 工厂启动任务 主函数运行

package com.jk.controller;

import java.text.ParseException;

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;

public class TestDingshiqi {

public static void main(String[] args) throws
SchedulerException, ParseException {
// 实例化 定时器工厂
SchedulerFactory gSchedulerFactory =
new StdSchedulerFactory();
// 通过工厂获得任务调度器
Scheduler sche =
gSchedulerFactory.getScheduler();
// 设置 定时执行的 任务类 设定 任务名
JobDetail jobDetail = new JobDetail("testJob任
意起名字最好和业务相关", "JOB_GROUP_New1",
TestDing.class);// 任务名，任务组，任务执行类
// 获得 触发器 将任务添加到 指定的 触发器中
CronTrigger trigger = new CronTrigger
("testtrigger任意起名字最好和业务相关",
"TRIGGER_GROUP_name1");// 触发器名,触发器组
// 设置触发器的时间
trigger.setCronExpression("0/1 * * * * ?");//
触发器时间设定
//将触发器和 任务 放到 调度器中
sche.scheduleJob(jobDetail, trigger);
// 启动
if (!sche.isShutdown()) {
sche.start();
}
}

}

3. 封装的定时任务管理工具类
package com.jk.controller;

import org.quartz.CronTrigger;
import org.quartz.JobDetail;
import org.quartz.Scheduler;

/**

spring项目中整合定时器

一 : spring-quartz.xml

注入schedulerFactoryBean工厂

<bean id="schedulerFactoryBean" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">

在service层中通过属性注入或者自动注入都可以,这里使用到了自动注入

@Autowired
private SchedulerFactoryBean schedulerFactoryBean;

public void test() throws Exception {
// 通过工厂获得任务调度器
Scheduler sche = schedulerFactoryBean.getScheduler();
// 设置 定时执行的 任务类 设定 任务名
JobDetail jobDetail = new JobDetail("testJob任意起名字最好和业务相关", "JOB_GROUP_New1", SpringTask.class);// 任务名，任务组，任务执行类
// 获得 触发器 将任务添加到 指定的 触发器中
CronTrigger trigger = new CronTrigger("testtrigger任意起名字最好和业务相关", "TRIGGER_GROUP_name1");// 触发器名,触发器组
// 设置触发器的时间
trigger.setCronExpression("0/3 * * * * ?");// 触发器时间设定
//将触发器和 任务 放到 调度器中
sche.scheduleJob(jobDetail, trigger);
// 启动
if (!sche.isShutdown()) {
sche.start();
}
}

每次都要使用工厂创建比较麻烦可以将创建一个工具类:

package com.jk.util;

import org.quartz.CronTrigger;
import org.quartz.JobDetail;
import org.quartz.Scheduler;

public class QuartzManager {

private static String JOB_GROUP_NAME = "EXTJWEB_JOBGROUP_NAME";
private static String TRIGGER_GROUP_NAME = "EXTJWEB_TRIGGERGROUP_NAME";

CronTrigger trigger = new CronTrigger(jobName, TRIGGER_GROUP_NAME);// 触发器名,触发器组
trigger.setCronExpression(time);// 触发器时间设定
sched.scheduleJob(jobDetail, trigger);
// 启动
if (!sched.isShutdown()) {
sched.start();
}

throw new RuntimeException(e);
