Spring定时器Quartz的用法

首先导入需要的两个jar:

spring-context-support-4.1.1.RELEASE.jar

quartz-2.2.1.jar

1.创建两个类：

2.

QuartzConfiguration：

package com.baibeiyun.yunbang.common.webservice;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor;
import org.springframework.scheduling.quartz.CronTriggerFactoryBean;
import org.springframework.scheduling.quartz.JobDetailFactoryBean;
import org.springframework.scheduling.quartz.SchedulerFactoryBean;

@Configuration
public class QuartzConfiguration {

    @SuppressWarnings("unused")
    private final Logger log = LoggerFactory.getLogger(getClass());

    @Bean
    public SchedulerFactoryBean schedulerFactory() {
        SchedulerFactoryBean schedulerFactoryBean = new SchedulerFactoryBean();
        schedulerFactoryBean.setTriggers(cronTriggerFactoryBean().getObject());
        schedulerFactoryBean.setTaskExecutor(threadPoolTaskExecutor());
        schedulerFactoryBean.setApplicationContextSchedulerContextKey("applicationContext");
        return schedulerFactoryBean;
    }
    @Bean
    public CronTriggerFactoryBean cronTriggerFactoryBean() {
        CronTriggerFactoryBean cronTriggerFactoryBean = new CronTriggerFactoryBean();
        cronTriggerFactoryBean.setJobDetail(jobDetailFactoryBean().getObject());
        cronTriggerFactoryBean.setCronExpression("0 0/1 * * * ?");
        //cronTriggerFactoryBean.setCronExpression("0/5 * * * * ?");
        return cronTriggerFactoryBean;
    }
    @Bean
    public JobDetailFactoryBean jobDetailFactoryBean() {
        JobDetailFactoryBean jobDetailFactoryBean = new JobDetailFactoryBean();
        jobDetailFactoryBean.setJobClass(WorkorderCheckJob.class);
        jobDetailFactoryBean.setDurability(true);
        return jobDetailFactoryBean;
    }
    @Bean
    public ThreadPoolTaskExecutor threadPoolTaskExecutor() {
        ThreadPoolTaskExecutor threadPoolTaskExecutor = new ThreadPoolTaskExecutor();
        threadPoolTaskExecutor.setCorePoolSize(10);
        threadPoolTaskExecutor.setMaxPoolSize(20);
        threadPoolTaskExecutor.setQueueCapacity(5);
        threadPoolTaskExecutor.setKeepAliveSeconds(100);
        return threadPoolTaskExecutor;
    }

}

3.WorkorderCheckJob：

package com.textile.quartz;

import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.quartz.SchedulerException;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.scheduling.quartz.QuartzJobBean;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

/**
 * Created by Administrator on 2016/12/4.
 */
@Service
@Transactional
public class WorkorderCheckJob extends QuartzJobBean{
    @SuppressWarnings("unused")
    private final Logger log = LoggerFactory.getLogger(getClass());

    private static boolean isRun = false;

    protected void executeInternal(JobExecutionContext executionContext) throws JobExecutionException {
        if (isRun) {
            System.out.println("前一次未执行完,跳过本次任务!");
            return;
        }
        isRun = true;
        task(executionContext);
        isRun = false;
        System.out.println("执行逻辑-isRunFinish");

    }

    private void task(JobExecutionContext executionContext) {
        try {
            ApplicationContext applicationContext = (ApplicationContext) executionContext.getScheduler().getContext().get("applicationContext");

            //AppInstanceService appInstanceService = (AppInstanceService)applicationContext.getBean(AppInstanceService.class);
            //appInstanceService.clearInstanceTime();

        } catch (BeansException e) {
            e.printStackTrace();

        } catch (SchedulerException e) {
            e.printStackTrace();
        }
        catch (Exception e) {
            e.printStackTrace();
        }
    }
}

4.定时的任务在第三步的类中的executeInternal执行，定时的配置信息在以上的第二步的类中。
