要將Quartz插件集成到Spring Boot應用程序中,可以按照以下步驟操作:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-quartz</artifactId>
</dependency>
spring.quartz.job-store-type=jdbc
spring.quartz.properties.org.quartz.scheduler.instanceName=myScheduler
spring.quartz.properties.org.quartz.scheduler.instanceId=AUTO
spring.quartz.properties.org.quartz.jobStore.class=org.quartz.impl.jdbcjobstore.JobStoreTX
spring.quartz.properties.org.quartz.jobStore.driverDelegateClass=org.quartz.impl.jdbcjobstore.StdJDBCDelegate
spring.quartz.properties.org.quartz.jobStore.tablePrefix=QRTZ_
spring.quartz.properties.org.quartz.jobStore.isClustered=true
spring.quartz.properties.org.quartz.jobStore.clusterCheckinInterval=20000
spring.quartz.properties.org.quartz.threadPool.class=org.quartz.simpl.SimpleThreadPool
spring.quartz.properties.org.quartz.threadPool.threadCount=10
創建Quartz Job類:編寫一個實現Job接口的任務類,實現具體的任務邏輯。
創建JobDetail和Trigger:在Spring配置類中配置JobDetail和Trigger,并將它們與Quartz Scheduler集成。
@Autowired
private ApplicationContext applicationContext;
@Bean
public JobDetail jobDetail() {
return JobBuilder.newJob().ofType(MyJob.class)
.storeDurably()
.withIdentity("myJob")
.withDescription("My Job Description")
.build();
}
@Bean
public Trigger trigger(JobDetail job) {
return TriggerBuilder.newTrigger()
.forJob(job)
.withIdentity("myTrigger")
.withSchedule(CronScheduleBuilder.cronSchedule("0/30 * * * * ?"))
.build();
}
@Bean
public Scheduler scheduler(JobDetail job, Trigger trigger) throws SchedulerException {
StdSchedulerFactory factory = new StdSchedulerFactory();
factory.initialize(new ClassPathResource("quartz.properties").getInputStream());
Scheduler scheduler = factory.getScheduler();
scheduler.setJobFactory(new AutowiringSpringBeanJobFactory(applicationContext));
scheduler.scheduleJob(job, trigger);
scheduler.start();
return scheduler;
}
public class AutowiringSpringBeanJobFactory extends SpringBeanJobFactory implements ApplicationContextAware {
private transient AutowireCapableBeanFactory beanFactory;
public AutowiringSpringBeanJobFactory(ApplicationContext context) {
beanFactory = context.getAutowireCapableBeanFactory();
}
@Override
protected Object createJobInstance(final TriggerFiredBundle bundle) throws Exception {
final Object job = super.createJobInstance(bundle);
beanFactory.autowireBean(job);
return job;
}
}
通過以上步驟,您就可以成功將Quartz插件集成到Spring Boot應用程序中,并使用Quartz來調度任務。
