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 -->
lt;dependency>
<groupId>org.quartz-scheduler</groupId>
<artifactId>quartz</artifactId>
<version>1.8.5</version>
lt;/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;

/**

@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

                            jobDetail.setName(job.getId());
                        } else {

                        }
                        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);

}

 

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！（企业架构源码可以加求球：三五三六二四七二五九）
