springboot整合Quartz实现定时任务

1.maven依赖：

<!--quartz-->
<dependency>
<groupId>org.quartz-scheduler</groupId>
<artifactId>quartz</artifactId>
<version>2.2.1</version>
</dependency>
<!-- 该依赖必加，里面有sping对schedule的支持 -->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context-support</artifactId>
</dependency>

2.定时任务配置类

import org.quartz.Scheduler;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.scheduling.quartz.SchedulerFactoryBean;

/**
* 定时任务配置
*
* @author yangfeng
* @date 2018-07-03
*/
@Configuration
public class QuartzConfig {
@Autowired
private SpringJobFactory springJobFactory;

@Bean
public SchedulerFactoryBean schedulerFactoryBean() {
SchedulerFactoryBean schedulerFactoryBean = new SchedulerFactoryBean();
schedulerFactoryBean.setJobFactory(springJobFactory);
return schedulerFactoryBean;
}

@Bean
public Scheduler scheduler() {
return schedulerFactoryBean().getScheduler();
}
}

3.配置job交给spring管理，主要目的就是解决job类注入其他service或者使用Spring组件

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;

@Component
public class SpringJobFactory extends AdaptableJobFactory {

@Autowired
private AutowireCapableBeanFactory capableBeanFactory;

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

4.定时任务创建job，通过注入Scheduler对任务进行操作

import org.quartz.*;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

/**
* 定时任务服务
*
* @author yangfeng
* @date 2018-07-03
*/
@Service
public class QuartzService {

private static final String JOB_GROUP = "event_job_group";
private static final String TRIGGER_GROUP = "event_trigger_group";
@Autowired
private Scheduler scheduler;

/**
* 创建定时任务
* @param jobDetailName
* @param cronExpression
* @param jobClass
* @throws SchedulerException
*/
public void createScheduleJob(String jobDetailName, String cronExpression, Class<? extends Job> jobClass) throws SchedulerException {
JobDetail jobDetail = JobBuilder.newJob(jobClass)
.withIdentity("task_" + jobDetailName, JOB_GROUP).storeDurably().requestRecovery().build();
CronScheduleBuilder scheduleBuilder = CronScheduleBuilder.cronSchedule(cronExpression);
Trigger trigger = TriggerBuilder.newTrigger().withIdentity("task_" + jobDetailName, TRIGGER_GROUP).withSchedule(scheduleBuilder).build();
scheduler.scheduleJob(jobDetail, trigger);
}
}

5.任务执行类，具体业务逻辑

import com.jp.zpzc.service.IUserVoteService;
import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import javax.annotation.Resource;

/**
* 投票统计
*
* @author yangfeng
* @date 2018-07-03
*/
public class VoteStatisticsTask implements Job {

private static Logger LOG = LoggerFactory.getLogger(VoteStatisticsTask.class);

@Resource
private IUserVoteService userVoteService;

@Override
public void execute(JobExecutionContext jobExecutionContext) {
//统计已结束的投票
userVoteService.updateVote();
}
}

6.启动监听去初始化Quartz

import org.quartz.SchedulerException;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.ApplicationListener;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.event.ContextRefreshedEvent;

/**
* 监听器，启动定时任务
*
* @author yangfeng
* @date 2018-07-03
*/
@Configuration
public class ApplicationStartQuartzJobListener implements ApplicationListener<ContextRefreshedEvent> {
private static Logger LOG = LoggerFactory.getLogger(ApplicationStartQuartzJobListener.class);

@Autowired
private QuartzService quartzService;

/**
* 初始启动quartz
*/
@Override
public void onApplicationEvent(ContextRefreshedEvent event) {
try {
//成分分析
//quartzService.createScheduleJob("IngredientAnalysisTask", "*/5 * * * * ?", IngredientAnalysisTask.class);
//投票统计
quartzService.createScheduleJob("VoteStatisticsTask", "*/5 * * * * ?", VoteStatisticsTask.class);
LOG.info("任务已经启动...");
} catch (SchedulerException e) {
LOG.error(e.getMessage());
}
}
}
