SpringBoot开发案例之整合Quartz注入Service

缘由

简单来说就是quartz中的Job是在quartz中实例化出来的，不受spring的管理，所以就导致注入不进去了。

解决

定义SpringJobFactory类：

/**
 * 解决spring bean注入Job的问题
 */
@Component  
public class SpringJobFactory 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;    
    }    
}

quartz配置：

/**

 */
@Configuration
public class SchedulerConfig {
    
    @Autowired
    private SpringJobFactory springJobFactory;
    
    @Bean(name="SchedulerFactory")
    public SchedulerFactoryBean schedulerFactoryBean() throws IOException {
        SchedulerFactoryBean factory = new SchedulerFactoryBean();
        factory.setAutoStartup(true);
        factory.setStartupDelay(5);//延时5秒启动
        factory.setQuartzProperties(quartzProperties());
        //注意这里是重点
        factory.setJobFactory(springJobFactory);  
        return factory;
    }

    @Bean
    public Properties quartzProperties() throws IOException {
        PropertiesFactoryBean propertiesFactoryBean = new PropertiesFactoryBean();
        propertiesFactoryBean.setLocation(new ClassPathResource("/quartz.properties"));
        propertiesFactoryBean.afterPropertiesSet();
        return propertiesFactoryBean.getObject();
    }

    /*
     * quartz初始化监听器
     */
    @Bean
    public QuartzInitializerListener executorListener() {
       return new QuartzInitializerListener();
    }

    /*
     * 通过SchedulerFactoryBean获取Scheduler的实例
     */
    @Bean(name="Scheduler")
    public Scheduler scheduler() throws IOException {
        return schedulerFactoryBean().getScheduler();
    }

}

测试任务案例TestJob：

/**
 * 实现序列化接口、防止重启应用出现quartz Couldn't retrieve job because a required class was not found 的问题
 */
public class TestJob implements  Job,Serializable {

    private static final long serialVersionUID = 1L;
       
    @Autowired  
    private IJobService jobService; 
    
    @Override
    public void execute(JobExecutionContext context) throws JobExecutionException {
        System.out.println(jobService);//注入jobService 执行相关业务操作
        System.out.println("任务执行成功");
    }
}
