quartz任务类自动依赖注入

quartz与spring整合时, 任务Job不是由spring管理创建的,想用@Autowired在任务类中注入其他依赖无法生效。可扩展生成任务的工厂,创建好任务后,利用AutowireCapableBeanFactory的autowireBean()方法注入依赖。示例代码如下。

package com.susq.common.task.quartz.config;

import lombok.extern.slf4j.Slf4j;
import org.quartz.spi.TriggerFiredBundle;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.config.AutowireCapableBeanFactory;
import org.springframework.boot.autoconfigure.quartz.SchedulerFactoryBeanCustomizer;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.io.ClassPathResource;
import org.springframework.core.io.Resource;
import org.springframework.lang.NonNull;
import org.springframework.scheduling.quartz.SchedulerFactoryBean;
import org.springframework.scheduling.quartz.SpringBeanJobFactory;
import org.springframework.stereotype.Component;

/**

@Slf4j
@Configuration
public class QuartzConfiguration {

    @Component
    static class MySchedulerFactoryBeanCustomizer implements SchedulerFactoryBeanCustomizer {

        @Autowired
        private AutowiringSpringBeanJobFactory autowiringSpringBeanJobFactory;

        @Override
        public void customize(SchedulerFactoryBean schedulerFactoryBean) {
            log.info("my custom SchedulerFactoryBean");
            Resource resource = new ClassPathResource("quartz.properties");
            if (resource.exists()) {
                schedulerFactoryBean.setConfigLocation(resource);
            }
            schedulerFactoryBean.setJobFactory(autowiringSpringBeanJobFactory);
        }
    }
    
	@Component
    static class AutowiringSpringBeanJobFactory extends SpringBeanJobFactory {

        @Autowired
        private AutowireCapableBeanFactory capableBeanFactory;

        @Override
        @NonNull
        protected Object createJobInstance(final TriggerFiredBundle bundle) throws Exception {
            final Object job = super.createJobInstance(bundle);
            capableBeanFactory.autowireBean(job);
            return job;
        }

    }
}
