Spring4+Springmvc+quartz实现多线程动态定时调度

scheduler定时调度系统是大多行业项目都需要的，传统的spring-job模式，个人感觉已经out了，因为存在很多的问题，特别是定时调度的追加、修改、删除等，需要修改xml，xml的配置生效无非是热部署灰度发布方案或者直接停止、重启服务器，完全不能做到自动启动、修复方式。

提醒：可以对应用进行集群部署，在对定时调度配置时可以使用集群方式或者单边配置应用方式，今天讲解的是使用spring4+scheduler实现定时调度，闲话少说，直接把步骤记录下来：

 

1. 在项目的pom.xml文件中引入quartz的jar包，如下：

                <!-- quartz定时调度 -->
		<dependency>
			<groupId>org.quartz-scheduler</groupId>
			<artifactId>quartz</artifactId>
			<version>1.8.5</version>
		</dependency>

 

2. 定义quartz的配置文件spring-context-quartz.xml：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="
		http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
		http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd"
	default-lazy-init="false">
	<!-- 调度器 -->
    <bean name="scheduler" class="org.springframework.scheduling.quartz.SchedulerFactoryBean"> 
       <!-- 通过applicationContextSchedulerContextKey属性配置spring上下文 -->    
        <property name="applicationContextSchedulerContextKey" value="applicationContext" />
    </bean>  
    <!--加载数据库任务-->
    <bean id="jobService" class="com.ml.honghu.job.service.JobService" init-method="loadJob" />
</beans>

  

3.  在项目的web.xml文件中引入spring-context-quartz.xml配置文件

classpath*:spring-context-quartz.xml

 

4. 定义job实体对象

public class Job{
	
	private static final long serialVersionUID = 1L;
	
	/**
	 * 任务执行周期cron表达式
	 */
	public static int EXECYCLE_CRON = 2;
	/**
	 * 任务执行周期自定义
	 */
	public static int EXECYCLE_DEFINE = 1;
	/**
	 * 执行周期-分钟
	 */
	public static int EXECYCLE_MINUTE = 1;
	/**
	 * 执行周期-小时
	 */
	public static int EXECYCLE_HOUR = 2;
	/**
	 * 执行周期-日
	 */
	public static int EXECYCLE_DAY = 3;
	/**
	 * 执行周期-月
	 */
	public static int EXECYCLE_WEEK = 4;
	/**
	 * 执行周期-月
	 */
	public static int EXECYCLE_MONTH = 5;
	

	private String jobType;		// 任务类型(1首页静态化、2栏目页静态化、3内容页静态化、4采集、5分发)
	private String jobName;		// 任务名称
	private String jobClass;		// 任务类
	private String execycle;		// 执行周期分类(1非表达式 2 cron表达式)
	private String dayOfMonth;		// 每月的哪天
	private String dayOfWeek;		// 周几
	private String hour;		// 小时
	private String minute;		// 分钟
	private String intervalHour;		// 间隔小时
	private String intervalMinute;		// 间隔分钟
	private String jobIntervalUnit;		// 1分钟、2小时、3日、4周、5月
	private String cronExpression;		// 规则表达式
	private String isEnable;		// 是否启用
	
	public Job() {
		super();
	}

	public Job(String id){
		super(id);
	}

	@Length(min=1, max=1, message="任务类型(1首页静态化、2栏目页静态化、3内容页静态化、4采集、5分发)长度必须介于 1 和 1 之间")
	public String getJobType() {
		return jobType;
	}

	public void setJobType(String jobType) {
		this.jobType = jobType;
	}
	
	@Length(min=1, max=255, message="任务名称长度必须介于 1 和 255 之间")
	public String getJobName() {
		return jobName;
	}

	public void setJobName(String jobName) {
		this.jobName = jobName;
	}
	
	@Length(min=1, max=255, message="任务类长度必须介于 1 和 255 之间")
	public String getJobClass() {
		return jobClass;
	}

	public void setJobClass(String jobClass) {
		this.jobClass = jobClass;
	}
	
	@Length(min=1, max=1, message="执行周期分类(1非表达式 2 cron表达式)长度必须介于 1 和 1 之间")
	public String getExecycle() {
		return execycle;
	}

	public void setExecycle(String execycle) {
		this.execycle = execycle;
	}
	
	@Length(min=0, max=11, message="每月的哪天长度必须介于 0 和 11 之间")
	public String getDayOfMonth() {
		return dayOfMonth;
	}

	public void setDayOfMonth(String dayOfMonth) {
		this.dayOfMonth = dayOfMonth;
	}
	
	@Length(min=0, max=1, message="周几长度必须介于 0 和 1 之间")
	public String getDayOfWeek() {
		return dayOfWeek;
	}

	public void setDayOfWeek(String dayOfWeek) {
		this.dayOfWeek = dayOfWeek;
	}
	
	@Length(min=0, max=11, message="小时长度必须介于 0 和 11 之间")
	public String getHour() {
		return hour;
	}

	public void setHour(String hour) {
		this.hour = hour;
	}
	
	@Length(min=0, max=11, message="分钟长度必须介于 0 和 11 之间")
	public String getMinute() {
		return minute;
	}

	public void setMinute(String minute) {
		this.minute = minute;
	}
	
	@Length(min=0, max=11, message="间隔小时长度必须介于 0 和 11 之间")
	public String getIntervalHour() {
		return intervalHour;
	}

	public void setIntervalHour(String intervalHour) {
		this.intervalHour = intervalHour;
	}
	
	@Length(min=0, max=11, message="间隔分钟长度必须介于 0 和 11 之间")
	public String getIntervalMinute() {
		return intervalMinute;
	}

	public void setIntervalMinute(String intervalMinute) {
		this.intervalMinute = intervalMinute;
	}
	
	@Length(min=0, max=1, message="1分钟、2小时、3日、4周、5月长度必须介于 0 和 1 之间")
	public String getJobIntervalUnit() {
		return jobIntervalUnit;
	}

	public void setJobIntervalUnit(String jobIntervalUnit) {
		this.jobIntervalUnit = jobIntervalUnit;
	}
	
	@Length(min=0, max=255, message="规则表达式长度必须介于 0 和 255 之间")
	public String getCronExpression() {
		return cronExpression;
	}

	public void setCronExpression(String cronExpression) {
		this.cronExpression = cronExpression;
	}
	
	@Length(min=1, max=1, message="是否启用长度必须介于 1 和 1 之间")
	public String getIsEnable() {
		return isEnable;
	}

	public void setIsEnable(String isEnable) {
		this.isEnable = isEnable;
	}
	
}

 

5. 编写quartz的jobServvice类：

package com.ml.honghu.job.service;

import java.text.ParseException;
import java.util.List;
import java.util.UUID;

import org.quartz.CronTrigger;
import org.quartz.JobDetail;
import org.quartz.Scheduler;
import org.quartz.SchedulerException;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import com.ml.honghu.StringUtils;
import com.ml.honghu.common.persistence.Page;
import com.ml.honghu.common.service.CrudService;
import com.ml.honghu.job.dao.JobDao;
import com.ml.honghu.job.entity.Job;

/**
 * 定时调度任务Service
 * 
 * @author honghu
 */
@Service
@Transactional(readOnly = true)
public class JobService extends CrudService<JobDao, Job> {
	
	@Autowired
	private JobDao jobDao;
	
	private Logger logger = LoggerFactory.getLogger(getClass());

	public Job get(String id) {
		return super.get(id);
	}

	public List<Job> findList(Job job) {
		return super.findList(job);
	}

	public Page<Job> findPage(Page<Job> page, Job job) {
		return super.findPage(page, job);
	}

	@Transactional(readOnly = false)
	public void save(Job job) {
		super.save(job);
		// 启用则启动任务
		if (StringUtils.equals("1", job.getIsEnable())) {
			startTask(job, job.getId());
		}
	}
	
	@Transactional(readOnly = false)
	public void update(Job job) {
		//结束定时调度
		endTask(job.getId());
		
		job.preUpdate();
		jobDao.update(job);
		
		// 启用则启动任务
		if (StringUtils.equals("1", job.getIsEnable())) {
			startTask(job, job.getId());
		}
	}

	@Transactional(readOnly = false)
	public void delete(Job job) {
		//结束任务
		endTask(job.getId());
		
		super.delete(job);
	}

	/**
	 * 系统初始加载任务
	 */
	public void loadJob() throws Exception {
		List<Job> jobList = this.findList(new Job());
		if (null != jobList && jobList.size() > 0) {
			for (int i = 0; i < jobList.size(); i++) {
				Job job = jobList.get(i);
				// 任务开启状态 执行任务调度
				if (StringUtils.equals("1", job.getIsEnable())) {
					try {
						JobDetail jobDetail = new JobDetail();
						// 设置任务名称
						if (StringUtils.isNotBlank(job.getId())) {
							jobDetail.setName(job.getId());
						} else {
							UUID uuid = UUID.randomUUID();
							jobDetail.setName(uuid.toString());
							job.setId(uuid.toString());
						}
						jobDetail.setGroup(Scheduler.DEFAULT_GROUP);
						// 设置任务执行类
						jobDetail.setJobClass(getClassByTask(job.getJobClass()));
						// 添加任务参数
						CronTrigger cronTrigger = new CronTrigger("cron_" + i, Scheduler.DEFAULT_GROUP,
								jobDetail.getName(), Scheduler.DEFAULT_GROUP);

						cronTrigger.setCronExpression(getCronExpressionFromDB(job.getId()));
						// 调度任务
						scheduler.scheduleJob(jobDetail, cronTrigger);
					} catch (SchedulerException e) {
						logger.error("JobService SchedulerException", e);
					} catch (ClassNotFoundException e) {
						logger.error("JobService ClassNotFoundException", e);
					} catch (Exception e) {
						logger.error("JobService Exception", e);
					}
				}
			}
		}
	}

	/**
	 * 
	 * @param taskClassName
	 *            任务执行类名
	 * @return
	 * @throws ClassNotFoundException
	 */
	@SuppressWarnings("rawtypes")
	private Class getClassByTask(String taskClassName) throws ClassNotFoundException {
		return Class.forName(taskClassName);
	}

	public String getCronExpressionFromDB(String id) throws Exception {
		// 设置任务规则
		Job job = this.get(id);
		if (null != job) {
			if (Job.EXECYCLE_CRON == Integer.parseInt(job.getExecycle())) {
				return job.getCronExpression();
			} else {
				Integer execycle = Integer.parseInt(job.getJobIntervalUnit());
				String excep = "";
				if (execycle.equals(Job.EXECYCLE_MONTH)) {
					excep = "0  " + job.getMinute() + " " + job.getHour() + " " + job.getDayOfMonth() + " * ?";
				} else if (execycle.equals(Job.EXECYCLE_WEEK)) {
					excep = "0  " + job.getMinute() + " " + job.getHour() + " " + " ? " + " * " + job.getDayOfWeek();
				} else if (execycle.equals(Job.EXECYCLE_DAY)) {
					excep = "0  " + job.getMinute() + " " + job.getHour() + " " + " * * ?";
				} else if (execycle.equals(Job.EXECYCLE_HOUR)) {
					excep = "0 0 */" + job.getIntervalHour() + " * * ?";
				} else if (execycle.equals(Job.EXECYCLE_MINUTE)) {
					excep = "0  */" + job.getIntervalMinute() + " * * * ?";
				}
				return excep;
			}
		}
		return "";
	}

	private void startTask(Job job, String id) {
		try {
			String cronExpress = getCronExpressionFromDB(id);
			if (StringUtils.isNotEmpty(cronExpress) && cronExpress.indexOf("null") == -1) {
				JobDetail jobDetail = new JobDetail();
				jobDetail.setName(id);
				jobDetail.setGroup(Scheduler.DEFAULT_GROUP);
				jobDetail.setJobClass(getClassByTask(job.getJobClass()));
				CronTrigger cronTrigger = new CronTrigger("cron_" + id, Scheduler.DEFAULT_GROUP, jobDetail.getName(),
						Scheduler.DEFAULT_GROUP);
				cronTrigger.setCronExpression(cronExpress);
				scheduler.scheduleJob(jobDetail, cronTrigger);
			}
		} catch (ParseException e) {
			logger.error("JobService ParseException", e);
		} catch (Exception e) {
			logger.error("JobService Exception", e);
		}
	}
	
	private void endTask(String id) {
		try {
			scheduler.deleteJob(id, Scheduler.DEFAULT_GROUP);
		} catch (SchedulerException e) {
			logger.error("JobService endTask", e);
		}
	}

	@Autowired
	private Scheduler scheduler;

}

 

6. 编写相关job的Controller、dao、dao.xml我这边就不写了，其实就是对数据的增删改查操作

 

7. 启动项目验证quartz是否成功：

    项目启动个控制台：

      任务列表：

       任务添加和修改界面：

 到此完毕！
