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，
1. 在项目的pom.xml文件中引入quartz的jar包，如下：Java代码
lt;dependency>
org.quartz-scheduler
quartz
1.8.5
lt;/dependency>
[java]view plaincopyprint?
lt;dependency>
org.quartz-scheduler
quartz
1.8.5
lt;/dependency>
org.quartz-scheduler
quartz
1.8.5
2. 定义quartz的配置文件spring-context-quartz.xml：
Java代码
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">
[java]view plaincopyprint?
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">
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">
3. 在项目的web.xml文件中引入spring-context-quartz.xml配置文件
Java代码
classpath*:spring-context-quartz.xml
[java]view plaincopyprint?
classpath*:spring-context-quartz.xml
classpath*:spring-context-quartz.xml
4. 定义job实体对象

}
@Transactional(readOnly =false)

}
}
}

5. 编写quartz的jobServvice类：
Java代码
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)
publicclass JobServiceextends CrudService {
@Autowired
private JobDao jobDao;
private Logger logger = LoggerFactory.getLogger(getClass());
public Job get(String id) {
returnsuper.get(id);
}
public List findList(Job job) {
returnsuper.findList(job);
}
public Page findPage(Page page, Job job) {
returnsuper.findPage(page, job);
}
@Transactional(readOnly =false)
publicvoid 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)
publicvoid 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)
publicvoid delete(Job job) {
//结束任务
endTask(job.getId());
super.delete(job);
}
/**
* 系统初始加载任务
*/
publicvoid loadJob()throws Exception {
List 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);
}
}
}
}
}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：
Java代码
lt;dependency>
org.quartz-scheduler
quartz
1.8.5
lt;/dependency>
[java]view plaincopyprint?
lt;dependency>
org.quartz-scheduler
quartz
1.8.5
lt;/dependency>
org.quartz-scheduler
quartz
1.8.5
2. 定义quartz的配置文件spring-context-quartz.xml：
Java代码
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">
[java]view plaincopyprint?
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">
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">
3. 在项目的web.xml文件中引入spring-context-quartz.xml配置文件
Java代码
classpath*:spring-context-quartz.xml
[java]view plaincopyprint?
classpath*:spring-context-quartz.xml
classpath*:spring-context-quartz.xml
4. 定义job实体对象
Java代码
