Spring Boot集成Quartz注入Spring管理的类的方法
作者:沧海一滴
本篇文章主要介绍了Spring Boot集成Quartz注入Spring管理的类的方法,小编觉得挺不错的,现在分享给大家,也给大家做个参考。一起跟随小编过来看看吧
在Spring Boot中使用Quartz时,在JOB中一般需要引用Spring管理的Bean,通过定义Job Factory实现自动注入。
Spring有自己的Schedule定时任务,在Spring boot中使用的时候,不能动态管理JOB,于是就使用Quartz来实现。
在Spring Boot中配置Quartz:
import java.io.IOException; import java.util.Properties; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.beans.factory.config.PropertiesFactoryBean; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.core.io.ClassPathResource; import org.springframework.scheduling.annotation.EnableScheduling; import org.springframework.scheduling.quartz.SchedulerFactoryBean; @Configuration @EnableScheduling public class QuartzSchedule { @Autowired private MyJobFactory myJobFactory; @Bean public SchedulerFactoryBean schedulerFactoryBean() throws IOException { SchedulerFactoryBean factory = new SchedulerFactoryBean(); factory.setOverwriteExistingJobs(true); // 延时启动 factory.setStartupDelay(20); // 加载quartz数据源配置 factory.setQuartzProperties(quartzProperties()); // 自定义Job Factory,用于Spring注入 factory.setJobFactory(myJobFactory); return factory; } /** * 加载quartz数据源配置 * * @return * @throws IOException */ @Bean public Properties quartzProperties() throws IOException { PropertiesFactoryBean propertiesFactoryBean = new PropertiesFactoryBean(); propertiesFactoryBean.setLocation(new ClassPathResource("/quartz.properties")); propertiesFactoryBean.afterPropertiesSet(); return propertiesFactoryBean.getObject(); } }
为了在JOB中使用Spring管理的Bean,需要重新定义一个Job Factory:
@Component public class MyJobFactory extends AdaptableJobFactory { @Autowired private AutowireCapableBeanFactory capableBeanFactory; @Override protected Object createJobInstance(TriggerFiredBundle bundle) throws Exception { // 调用父类的方法 Object jobInstance = super.createJobInstance(bundle); // 进行注入 capableBeanFactory.autowireBean(jobInstance); return jobInstance; } }
然后在JOB中就可以使用Spring管理的Bean了
public class MyJob implements Job, Serializable { private static final long serialVersionUID = 1L; private Logger logger = LoggerFactory.getLogger(this.getClass()); @Autowired private SomeService someService; @Override public void execute(JobExecutionContext context) throws JobExecutionException { someService.doSomething(); } }
下面代码是创建JOB:
JobDetail jobDetail = JobBuilder.newJob(((Job) Class.forName(job.getClazz()).newInstance()).getClass()) .withIdentity(job.getJobName(), job.getJobGroup()).build(); jobDetail.getJobDataMap().put("extdata", job.getExtData()); // 表达式调度构建器 CronScheduleBuilder scheduleBuilder = CronScheduleBuilder.cronSchedule(job.getCronExpression()) .withMisfireHandlingInstructionDoNothing(); // 构建一个trigger TriggerBuilder<CronTrigger> triggerBuilder = TriggerBuilder.newTrigger().withIdentity(triggerKey) .withSchedule(scheduleBuilder); if (job.getStartTime() != null) { triggerBuilder.startAt(job.getStartTime()); } if (job.getEndTime() != null) { triggerBuilder.endAt(job.getEndTime()); } CronTrigger trigger = triggerBuilder.build(); scheduler.scheduleJob(jobDetail, trigger);// 注入到管理类
