Spring Boot集成Quartz注入Spring管理的类

转载自：https://my.oschina.net/hhaijun/blog/698498

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();
}
}
