关于quartz整合springboot的使用以及service注入
一、 Quartz主要有三个重要对象
- job:任务 -------- 你要做什么事？
- Trigger:触发器 -------- 你什么时候去做？
- Scheduler : 任务调度 -------- 你什么时候需要去做什么事？
二、quartz的基本使用
1.pom文件引入
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0modelVersion>
<groupId>com.demogroupId>
<artifactId>quartz-demoartifactId>
<version>0.0.1-SNAPSHOTversion>
<dependencies>
<dependency>
<groupId>org.quartz-schedulergroupId>
<artifactId>quartzartifactId>
<version>2.2.1version>
dependency>
dependencies>
project>
2.创建任务继承job类
/**
* 定义任务类
*
*
*/
public class QuartzDemo implements Job {
/**
* 任务被触发时所执行的方法
*/
public void execute(JobExecutionContext arg0) throws JobExecutionException {
System.out.println("Execute...."+new Date());
}
}3.编写测试代码
public class QuartzMain {
public static void main(String[] args) throws Exception {
// 1.创建Job对象：你要做什么事？
JobDetail job = JobBuilder.newJob(QuartzDemo.class).build();
/**
* 简单的trigger触发时间：通过Quartz提供一个方法来完成简单的重复调用 cron
* Trigger：按照Cron的表达式来给定触发的时间
*/
// 2.创建Trigger对象：在什么时间做？
/*Trigger trigger = TriggerBuilder.newTrigger().withSchedule(SimpleScheduleBuilder.repeatSecondlyForever())
.build();*/
Trigger trigger = TriggerBuilder.newTrigger().withSchedule(CronScheduleBuilder.cronSchedule("0/2 * * * * ?"))
.build();
// 3.创建Scheduler对象：在什么时间做什么事？
Scheduler scheduler = StdSchedulerFactory.getDefaultScheduler();
scheduler.scheduleJob(job, trigger);
//启动
scheduler.start();
}
}三、Quartz整合springboot
1.pom文件引入
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

2、编写Quartz启动类（任务类同上QuartzDemo）
/**
* Quartz配置类
*
*
*/
@Configuration
public class QuartzConfig {
/**
* 1.创建Job对象
*/
@Bean
public JobDetailFactoryBean jobDetailFactoryBean(){
JobDetailFactoryBean factory = new JobDetailFactoryBean();
//关联我们自己的Job类
factory.setJobClass(QuartzDemo.class);
return factory;
}
/**
* 2.创建Trigger对象
* 简单的Trigger
*/
@Bean
public SimpleTriggerFactoryBean simpleTriggerFactoryBean(JobDetailFactoryBean jobDetailFactoryBean){
SimpleTriggerFactoryBean factory = new SimpleTriggerFactoryBean();
//关联JobDetail对象
factory.setJobDetail(jobDetailFactoryBean.getObject());
//该参数表示一个执行的毫秒数
factory.setRepeatInterval(2000);
//重复次数
factory.setRepeatCount(5);
return factory;
}
/**
* 3.创建Scheduler对象
*/
@Bean
public SchedulerFactoryBean schedulerFactoryBean(SimpleTriggerFactoryBean simpleTriggerFactoryBean){
SchedulerFactoryBean factory = new SchedulerFactoryBean();
//关联trigger
factory.setTriggers(simpleTriggerFactoryBean.getObject());
return factory;
}
}3、springboot启动类需加注解@EnableScheduling
/**
*
*spring Boot 整合Quartz案例
*
*/
@SpringBootApplication
@EnableScheduling
public class App {
public static void main(String[] args) {
SpringApplication.run(App.class, args);
}
}四、在任务类种注入对象的异常问题
需编写一个MyAdaptableJobFactory类则可解决对象无法注入的问题
@Component("myAdaptableJobFactory")
public class MyAdaptableJobFactory extends AdaptableJobFactory {
//AutowireCapableBeanFactory 可以将一个对象添加到SpringIOC容器中，并且完成该对象注入
@Autowired
private AutowireCapableBeanFactory autowireCapableBeanFactory;
/**
* 该方法需要将实例化的任务对象手动的添加到springIOC容器中并且完成对象的注入
*/
@Override
protected Object createJobInstance(TriggerFiredBundle bundle) throws Exception {
Object obj = super.createJobInstance(bundle);
//将obj对象添加Spring IOC容器中，并完成注入
this.autowireCapableBeanFactory.autowireBean(obj);
return obj;
}
}修改QuartzConfig类（原始QuartzConfig同上Quartz整合springboot）
/**
* Quartz配置类
*
*
*/
@Configuration
public class QuartzConfig {
/**
* 1.创建Job对象
*/
@Bean
public JobDetailFactoryBean jobDetailFactoryBean(){
JobDetailFactoryBean factory = new JobDetailFactoryBean();
//关联我们自己的Job类
factory.setJobClass(QuartzDemo.class);
return factory;
}
/**
* 2.创建Trigger对象
*
*/
@Bean
public CronTriggerFactoryBean cronTriggerFactoryBean(JobDetailFactoryBean jobDetailFactoryBean){
CronTriggerFactoryBean factory = new CronTriggerFactoryBean();
factory.setJobDetail(jobDetailFactoryBean.getObject());
//设置触发时间
factory.setCronExpression("0/2 * * * * ?");
return factory;
}
/**
* 3.创建Scheduler对象
*/
@Bean
public SchedulerFactoryBean schedulerFactoryBean(CronTriggerFactoryBean cronTriggerFactoryBean,MyAdaptableJobFactory myAdaptableJobFactory){
SchedulerFactoryBean factory = new SchedulerFactoryBean();
//关联trigger
factory.setTriggers(cronTriggerFactoryBean.getObject());
factory.setJobFactory(myAdaptableJobFactory);
return factory;
}
}
