quartz是java里头定时任务的经典开源实现,这里讲述一下如何在springboot中集成quartz。
maven
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-tx</artifactId>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context-support</artifactId>
</dependency>
<dependency>
<groupId>org.quartz-scheduler</groupId>
<artifactId>quartz</artifactId>
<version>${quartz.version}</version>
</dependency>
<dependency>
<groupId>org.quartz-scheduler</groupId>
<artifactId>quartz-jobs</artifactId>
<version>${quartz.version}</version>
</dependency>
内存版配置
org.quartz.scheduler.instanceName=spring-boot-quartz-demo
org.quartz.scheduler.instanceId=AUTO
org.quartz.threadPool.threadCount=5
org.quartz.jobStore.class = org.quartz.simpl.RAMJobStore
quartz config
@Configuration
public class QuartzConfig {
public static final String QUARTZ_PROPERTIES_PATH = "/quartz.properties";
@Bean
public JobFactory jobFactory(ApplicationContext applicationContext) {
AutowiringSpringBeanJobFactory jobFactory = new AutowiringSpringBeanJobFactory();
jobFactory.setApplicationContext(applicationContext);
return jobFactory;
}
@Bean
public SchedulerFactoryBean schedulerFactoryBean(JobFactory jobFactory) throws IOException {
SchedulerFactoryBean factory = new SchedulerFactoryBean();
factory.setAutoStartup(true);
factory.setJobFactory(jobFactory);
factory.setQuartzProperties(quartzProperties());
return factory;
}
@Bean
public Properties quartzProperties() throws IOException {
PropertiesFactoryBean propertiesFactoryBean = new PropertiesFactoryBean();
propertiesFactoryBean.setLocation(new ClassPathResource(QUARTZ_PROPERTIES_PATH));
propertiesFactoryBean.afterPropertiesSet();
return propertiesFactoryBean.getObject();
}
public static class AutowiringSpringBeanJobFactory extends SpringBeanJobFactory implements
ApplicationContextAware {
private transient AutowireCapableBeanFactory beanFactory;
@Override
public void setApplicationContext(final 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;
}
}
}
demo job
@PersistJobDataAfterExecution
@DisallowConcurrentExecution
public class DemoJob implements Job{
private String jobArg;
@Autowired
DemoService demoService;
@Override
public void execute(JobExecutionContext context) throws JobExecutionException {
demoService.hello(jobArg);
}
public void setJobArg(String jobArg) {
this.jobArg = jobArg;
}
}
注册到quartz去调度
@Autowired
SchedulerFactoryBean schedulerFactoryBean;
public void scheduleJobs() throws SchedulerException {
Scheduler scheduler = schedulerFactoryBean.getScheduler();
JobDataMap jobDataMap = new JobDataMap();
jobDataMap.put("jobArg", "world");
JobDetail jobDetail = JobBuilder.newJob(DemoJob.class)
.setJobData(jobDataMap)
.withDescription("demo")
.withIdentity("demo-job", "demo-group")
.build();
Trigger trigger = TriggerBuilder.newTrigger()
.forJob(jobDetail)
.withSchedule(cronSchedule("0/5 * * * * ?"))
.build();
if(!scheduler.checkExists(JobKey.jobKey("demo-job","demo-group"))){
scheduler.scheduleJob(jobDetail,trigger);
}
scheduler.start();
}
使用postgres作为持久层版本
配置文件
#============================================================================
# Configure Main Scheduler Properties
#============================================================================
org.quartz.scheduler.instanceName=spring-boot-quartz-demo
org.quartz.scheduler.instanceId=AUTO
org.quartz.scheduler.skipUpdateCheck=true
#============================================================================
# Configure ThreadPool
#============================================================================
org.quartz.threadPool.class=org.quartz.simpl.SimpleThreadPool
org.quartz.threadPool.threadCount=5
org.quartz.threadPool.threadPriority=5
#============================================================================
# Configure JobStore
#============================================================================
org.quartz.jobStore.misfireThreshold=60000
org.quartz.jobStore.class=org.quartz.impl.jdbcjobstore.JobStoreTX
org.quartz.jobStore.driverDelegateClass=org.quartz.impl.jdbcjobstore.PostgreSQLDelegate
org.quartz.jobStore.useProperties=false
#org.quartz.jobStore.dataSource=dataSource
org.quartz.jobStore.tablePrefix=QRTZ_
org.quartz.jobStore.isClustered=true
设置数据源和数据管理器
@Bean
public SchedulerFactoryBean schedulerFactoryBean(JobFactory jobFactory, DataSource dataSource, PlatformTransactionManager transactionManager) throws IOException {
SchedulerFactoryBean factory = new SchedulerFactoryBean();
factory.setAutoStartup(true);
factory.setJobFactory(jobFactory);
factory.setQuartzProperties(quartzProperties());
//jdbc store
factory.setDataSource(dataSource);
factory.setTransactionManager(transactionManager);
return factory;
}
其他的配置不变
springboot项目正常配置datasource即可
