#spring分布式定时任务

本文记录了使用Spring结合Quartz实现分布式定时任务的步骤，包括AutowiringSpringBeanJobFactory、PersistableCronTriggerFactoryBean的配置，以及任务类和配置文件的详细设置。同时提到了通过@DisallowConcurrentExecution注解防止任务并发执行。

AutowiringSpringBeanJobFactory类：

import org.quartz.spi.TriggerFiredBundle;
import org.springframework.beans.BeansException;
import org.springframework.beans.factory.config.AutowireCapableBeanFactory;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
import org.springframework.scheduling.quartz.SpringBeanJobFactory;

/**
 * @author 
 * @description 使job类支持spring的自动注入
 * @date 2016-05-27
 */
public class AutowiringSpringBeanJobFactory extends SpringBeanJobFactory implements ApplicationContextAware
{
    private transient AutowireCapableBeanFactory beanFactory;

    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException
    {
        beanFactory = applicationContext.getAutowireCapableBeanFactory();
    }


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

PersistableCronTriggerFactoryBean类：

import java.text.ParseException;

import org.springframework.scheduling.quartz.CronTriggerFactoryBean;

/**
 * @author FengHaixin
 * @description 一句话描述该文件的用途
 * @date 2016-05-27
 */
public class PersistableCronTriggerFactoryBean extends CronTriggerFactoryBean
{

    @Override
    public void afterPropertiesSet() throws ParseException
    {
        super.afterPropertiesSet();
        getJobDataMap().remove(getObject().getJobKey().getName());
    }
}

执行的定时任务类：

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.scheduling.quartz.QuartzJobBean;

import com.kmei.common.util.DateUtil;

/**
 * @author 
 * @description 一句话描述该文件的用途
 * @date 2016-05-23
 */
public class PrintCurrentTimeJobs extends QuartzJobBean
{
    private static final Log LOG_RECORD = LogFactory.getLog(PrintCurrentTimeJobs.class);

    //这里就是因为有上文中的AutowiringSpringBeanJobFactory才可以使用@Autowired注解，否则只能在配置文件中设置这属性的值
    @Autowired
    private ClusterQuartz clusterQuartz;


    protected void executeInternal(JobExecutionContext jobExecutionContext) throws JobExecutionException
    {
        LOG_RECORD.info
