springboot-quartz普通任務與可傳參任務


兩者區別與作用:

普通任務:總調度(SchedulerFactoryBean)--> 定時調度器(CronTriggerFactoryBean) --> 調度明細自定義執行方法bean(MethodInvokingJobDetailFactoryBean) -->調度bean(我們定義的job類)

可傳參任務:總調度(SchedulerFactoryBean)--> 定時調度器(CronTriggerFactoryBean) -->  調度明細bean(JobDetailFactoryBean)

如上是我們在配置調度器時的具體步驟及相互之間的依賴,區別主要在調度明細bean上,普通任務是(MethodInvokingJobDetailFactoryBean),而可傳參任務是(JobDetailFactoryBean):

  1)普通任務可以自定義執行方法,也就是說在其配置的調度bean(我們定義的job類)中我們可以自定義調度器最終執行的方法,可以叫work1也可以叫work2,and so on。而且要記住的一點,必須是無入參的方法!!!(做了一個測試,測試目的是看通過此類型調度類型是否也能傳入參數所以定義了一個帶入參的自定義方法即public void work(JobExecutionContext jobExecutionContext),最中測試結果是spring quartz會報找不到work方法及No such method work(),其默認執行我們生命的work無入參的方法。

  2)可傳參任務必須繼承QuartzJobBean,重寫protected void executeInternal(JobExecutionContext jobExecutionContext) throws JobExecutionException方法,其中JobExecutionContext就是我們在定義調度器明細時傳入參數的上下文,我們可以通過JobExecutionContext取出傳入的map,調度任務最終執行的就是executeInternal方法,使用該調度明細任務無法使用自定義方法。

 

提供三種形式的定時任務:
1、固定等待時間 @Scheduled(fixedDelay = 時間間隔 )
2、固定間隔時間 @Scheduled(fixedRate = 時間間隔 )
3、Corn表達式 @Scheduled(cron = Corn表達式)

 

添加依賴(不知道為什么要加jboss-logging依賴,沒有會報錯)

@Configuration
public class QuartzConfigration {
        
    /** 
     * Details:配置定時任務 
     */  
    @Bean(name = "marketingActivityJobDetail")  
    public MethodInvokingJobDetailFactoryBean detailFactoryBean(ScheduleTask task) {// ScheduleTask為需要執行的任務

        jobDetail.setConcurrent(false);  
          
        jobDetail.setName("marketing_activity");// 設置任務的名字

        tigger.setJobDetail(jobDetail.getObject());  
        tigger.setCronExpression("0 0 1 * * ?");// 初始時的cron表達式 ,每天1點執行

3、定時查庫,並更新任務

package cloud.app.prod.home.quartz.mem;

import javax.annotation.Resource;

import org.quartz.CronScheduleBuilder;
import org.quartz.CronTrigger;
import org.quartz.JobDetail;
import org.quartz.Scheduler;
import org.quartz.SchedulerException;
import org.springframework.context.annotation.Configuration;
import org.springframework.scheduling.annotation.EnableScheduling;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;

import cloud.app.prod.home.common.FailException;
import cloud.app.prod.home.mem.vo.MarketingActivitiesVO;
import cloud.app.prod.home.utils.DSHUtils;

/**

 * Modified Date: 2018年3月31日 下午3:58:08 </br>
 * Version: 1.0 </br>
*/
@Configuration  
@EnableScheduling  
@Component
public class ScheduleRefreshCron {

    @Resource(name = "marketingActivityJobDetail")  
    private JobDetail jobDetail;  
  
    @Resource(name = "marketingActivityJobTrigger")  
    private CronTrigger cronTrigger;  
  
    @Resource(name = "marketingActivityScheduler")  
    private Scheduler scheduler;  
  
    @Scheduled(fixedRate = 5000) // 每隔5s查庫,並根據查詢結果決定是否重新設置定時任務
//    @Scheduled(cron = "0 0 1 * * ?")
    public void scheduleUpdateCronTrigger() throws SchedulerException, FailException {  
        CronTrigger trigger = (CronTrigger) scheduler.getTrigger(cronTrigger.getKey());  
        String currentCron = trigger.getCronExpression();// 當前Trigger使用的  
        String searchCron = "0 41 10 ? * *";// 從數據庫查詢出來的  
        System.out.println(currentCron);  
        System.out.println(searchCron);  
        
        // 如果當前使用的cron表達式和從數據庫中查詢出來的cron表達式一致,則不刷新任務
        if (!currentCron.equals(searchCron)) {  
            MarketingActivitiesVO marketingActivitiesVO = new MarketingActivitiesVO();
            marketingActivitiesVO.setId(DSHUtils.generateUUID());
            
            // 表達式調度構建器  
            CronScheduleBuilder scheduleBuilder = CronScheduleBuilder.cronSchedule(searchCron);  
            // 按新的cronExpression表達式重新構建trigger  
            trigger = (CronTrigger) scheduler.getTrigger(cronTrigger.getKey());  
            trigger = trigger.getTriggerBuilder().withIdentity(cronTrigger.getKey())  
                    .withSchedule(scheduleBuilder).build();  
            // 按新的trigger重新設置job執行  
            scheduler.rescheduleJob(cronTrigger.getKey(), trigger);  
            currentCron = searchCron;  
        }  
    } 
}

二、可傳參任務

在Spring Boot中使用Quartz時,如果job涉及到調用其他自定義方法,需要通過定義Job Factory實現自動注入

傳參關鍵代碼:

1)、接收參數

@Override
    protected void executeInternal(JobExecutionContext context) throws JobExecutionException {
        JobDataMap dataMap = context.getJobDetail().getJobDataMap();
        MarketingActivitiesVO marketingActivitiesVO = (MarketingActivitiesVO) dataMap.get("marketingActivitiesVO");
    }
View Code

2)、傳入參數

// 創建一項作業
            JobDetail job = JobBuilder.newJob(ScheduleTask.class)  
                    .withIdentity("marketingActivityJob", "marketingActivityGroup")  
                    .build();  
            
            // 設置參數
            MarketingActivitiesVO marketingActivitiesVO = new MarketingActivitiesVO();
            marketingActivitiesVO.setId(DSHUtils.generateUUID());
            job.getJobDataMap().put("marketingActivitiesVO", marketingActivitiesVO);
View Code

 

1、自定義MyJobFactory類

package cloud.app.prod.home.quartz;

import org.quartz.spi.TriggerFiredBundle;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.config.AutowireCapableBeanFactory;
import org.springframework.scheduling.quartz.AdaptableJobFactory;
import org.springframework.stereotype.Component;

/**
 * Author : YongBo Xie </br>
 * File Name: MyJobFactory.java </br>
 * Created Date: 2018年4月2日 下午3:27:30 </br>
 * Modified Date: 2018年4月2日 下午3:27:30 </br>
 * Version: 1.0 </br>
*/
@Component
public class MyJobFactory extends AdaptableJobFactory {
    
    @Autowired
    private AutowireCapableBeanFactory capableBeanFactory;

    @Override
    protected Object createJobInstance(TriggerFiredBundle bundle) throws Exception {
        // 調用父類的方法
        Object jobInstance = super.createJobInstance(bundle);
        // 進行注入
        capableBeanFactory.autowireBean(jobInstance);
        return jobInstance;
    }
}
View Code

2、配置SchedulerFactoryBean

package cloud.app.prod.home.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;

import cloud.app.prod.home.quartz.MyJobFactory;

/**

 * Modified Date: 2018年3月31日 下午3:42:04 </br>
 * Version: 1.0 </br>
*/
@Configuration
@EnableScheduling
public class QuartzConfigration {
    
    @Autowired
    private MyJobFactory myJobFactory; 
    
    @Bean 
    public SchedulerFactoryBean schedulerFactoryBean() throws IOException {
        SchedulerFactoryBean factory = new SchedulerFactoryBean();

        // 用於quartz集群,QuartzScheduler 啟動時更新己存在的Job
        factory.setOverwriteExistingJobs(true);
        
        // 延時啟動,應用啟動1秒后  
//        factory.setStartupDelay(1);

        // 加載quartz數據源配置
//        factory.setQuartzProperties(quartzProperties()); 

        // 自定義Job Factory,用於Spring注入
        factory.setJobFactory(myJobFactory);

        return factory;
    }
    
    /**
     * 加載quartz數據源配置
     * 
     * @return
     * @throws IOException
     */
    @Bean
    public Properties quartzProperties() throws IOException {
        PropertiesFactoryBean propertiesFactoryBean = new PropertiesFactoryBean();
        propertiesFactoryBean.setLocation(new ClassPathResource("/quartz.properties"));
        propertiesFactoryBean.afterPropertiesSet();
        return propertiesFactoryBean.getObject();
    }
}

import org.apache.log4j.Logger;
import org.quartz.DisallowConcurrentExecution;
import org.quartz.JobDataMap;
import org.quartz.JobExecutionContext;

 * Modified Date: 2018年3月31日 下午3:37:43 </br>
 * Version: 1.0 </br>
*/
@Configuration  
@Component // 此注解必加  
@EnableScheduling // 此注解必加
@DisallowConcurrentExecution // 任務同步
public class ScheduleTask extends QuartzJobBean {
    
    private static Logger logger = Logger.getLogger(ScheduleTask.class);
    @Autowired
    private MarketingActivitieRabbitMqSender marketingActivitieRabbitMqSender;

    @Override
    protected void executeInternal(JobExecutionContext context) throws JobExecutionException {
        logger.info("execute activity");
        JobDataMap dataMap = context.getJobDetail().getJobDataMap();
        MarketingActivitiesVO marketingActivitiesVO = (MarketingActivitiesVO) dataMap.get("marketingActivitiesVO");
        logger.info("marketingActivitiesVO.id: " + marketingActivitiesVO.getId());
        try {
            logger.info("marketingActivitieRabbitMqSender: " + marketingActivitieRabbitMqSender);
            marketingActivitieRabbitMqSender.sendRabbitmqDirect(marketingActivitiesVO);
        } catch (FailException e) {
            e.printStackTrace();
        }
    }
