本文主要是介绍spring quartz 动态时间(转自javaeye),希望对大家解决编程问题提供一定的参考价值,需要的开发者们随着小编来一起学习吧!
在项目中有一个需求,需要灵活配置调度任务时间,并能自由启动或停止调度。有关调度的实现我就第一就想到了Quartz这个开源调度组件,因为很多项目使用过,Spring结合Quartz静态配置调度任务时间,非常easy。比如:每天凌晨几点定时运行一个程序,这只要在工程中的spring配置文件中配置好spring整合quartz的几个属性就好。
Spring配置文件
引用
<bean id="jobDetail" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
<property name="targetObject" ref="simpleService" />
<property name="targetMethod" value="test" />
</bean>
<bean id="cronTrigger" class="org.springframework.scheduling.quartz.CronTriggerBean">
<property name="jobDetail" ref="jobDetail" />
<property name="cronExpression" value="0 0/50 * ? * * *" />
</bean>
<bean id="schedulerTrigger" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
<property name="triggers">
<list>
<ref bean="cronTrigger"/>
</list>
</property>
</bean>
这种配置就是对quartz的一种简单的使用了,调度任务会在spring启动的时候加载到内存中,按照cronTrigger中定义的 cronExpression定义的时间按时触发调度任务。但是这是quartz使用“内存”方式的一种配置,也比较常见,当然对于不使用spring的项目,也可以单独整合quartz。方法也比较简单,可以从quartz的doc中找到配置方式,或者看一下《Quartz Job Scheduling Framework 》。
但是对于想持久化调度任务的状态,并且灵活调整调度时间的方式来说,上面的内存方式就不能满足要求了,正如本文开始我遇到的情况,需要采用数据库方式集成 Quartz,这部分集成其实在《Quartz Job Scheduling Framework 》中也有较为详细的介绍,当然doc文档中也有,但是缺乏和spring集成的实例。
一、需要构建Quartz数据库表,建表脚本在Quartz发行包的docs\dbTables目录,里面有各种数据库建表脚本,我采用的Quartz 1.6.5版本,总共12张表,不同版本,表个数可能不同。我用mysql数据库,执行了Quartz发行包的docs\dbTables\tables_mysql_innodb.sql建表。
二、建立java project,完成后目录如下
三、配置数据库连接池
配置jdbc.properties文件
引用
jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/quartz?useUnicode=true&characterEncoding=UTF-8&autoReconnect=true
jdbc.username=root
jdbc.password=kfs
cpool.checkoutTimeout=5000
cpool.minPoolSize=10
cpool.maxPoolSize=25
cpool.maxIdleTime=7200
cpool.acquireIncrement=5
cpool.autoCommitOnClose=true
配置applicationContext.xml文件
引用
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

<!-- 属性文件读入 -->
<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations">
<list>
<value>classpath:jdbc.properties</value>
</list>
</property>
</bean>
<!-- 数据源定义,使用c3p0 连接池 -->
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">
<property name="driverClass" value="${jdbc.driverClassName}" />
<property name="jdbcUrl" value="${jdbc.url}" />
<property name="user" value="${jdbc.username}" />
<property name="password" value="${jdbc.password}" />
<property name="initialPoolSize" value="${cpool.minPoolSize}"/>
<property name="minPoolSize" value="${cpool.minPoolSize}" />
<property name="maxPoolSize" value="${cpool.maxPoolSize}" />
<property name="acquireIncrement" value="${cpool.acquireIncrement}" />
<property name="maxIdleTime" value="${cpool.maxIdleTime}"/>
</bean>
</beans>
这里只是配置了数据连接池,我使用c3p0 连接池,还没有涉及到Quartx有关配置,下面且听我慢慢道来。
四、实现动态定时任务
什么是动态定时任务:是由客户制定生成的,服务端只知道该去执行什么任务,但任务的定时是不确定的(是由客户制定)。
这样总不能修改配置文件每定制个定时任务就增加一个trigger吧,即便允许客户修改配置文件,但总需要重新启动web服务啊,研究了下Quartz在Spring中的动态定时,发现
引用
<bean id="cronTrigger" class="org.springframework.scheduling.quartz.CronTriggerBean" >
<property name="jobDetail" ref="schedulerJobDetail"/>
<property name="cronExpression">
<value>0/10 * * * * ?</value>
</property>
中cronExpression是关键,如果可以动态设置cronExpression的值,就可以顺利解决问题了。这样我们就不能直接使用org.springframework.scheduling.quartz.CronTriggerBean,需要自己实现一个动态调度服务类,在其中构建CronTrigger或SimpleTrigger,动态配置时间。

SchedulerService 只有一个多态方法schedule,SchedulerServiceImpl实现SchedulerService接口,注入org.quartz.Schedulert和org.quartz.JobDetail,schedule方法可以动态配置org.quartz.CronExpression或org.quartz.SimpleTrigger调度时间。
五、实现自己的org.quartz.JobDetail
在上一步中SchedulerServiceImpl需要注入org.quartz.JobDetail,在以前的静态配置中
引用
<bean id="jobDetail" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
<property name="targetObject" ref="simpleService" />
<property name="targetMethod" value="testMethod" />
</bean>
中使用org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean。在这里使用org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean。会报
引用

异常,google了一下,没有找到解决方法。所以在这里不能使用org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean。,不能pojo了,需要使用org.springframework.scheduling.quartz.JobDetailBean和org.springframework.scheduling.quartz.QuartzJobBean实现自己的QuartzJobBean,如下:
Java代码
1.package com.sundoctor.example.service;
2.
3.import org.quartz.JobExecutionContext;
4.import org.quartz.JobExecutionException;
5.import org.quartz.Trigger;
6.import org.springframework.scheduling.quartz.QuartzJobBean;
7.
8.public class MyQuartzJobBean extends QuartzJobBean {
9.
10. private SimpleService simpleService;
11.
12. public void setSimpleService(SimpleService simpleService) {
13. this.simpleService = simpleService;
14. }
15.
16. @Override
17. protected void executeInternal(JobExecutionContext jobexecutioncontext) throws JobExecutionException {
18. Trigger trigger = jobexecutioncontext.getTrigger();
19. String triggerName = trigger.getName();
20. simpleService.testMethod(triggerName);
21. }
22.
23.}
package com.sundoctor.example.service;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.quartz.Trigger;
import org.springframework.scheduling.quartz.QuartzJobBean;
public class MyQuartzJobBean extends QuartzJobBean {
private SimpleService simpleService;
public void setSimpleService(SimpleService simpleService) {
this.simpleService = simpleService;
}
@Override
protected void executeInternal(JobExecutionContext jobexecutioncontext) throws JobExecutionException {
Trigger trigger = jobexecutioncontext.getTrigger();
String triggerName = trigger.getName();
simpleService.testMethod(triggerName);
}
}
MyQuartzJobBean继承org.springframework.scheduling.quartz.QuartzJobBean,注入的SimpleService如下:
Java代码
1.package com.sundoctor.example.service;
2.
3.import java.io.Serializable;
4.
5.import org.slf4j.Logger;
6.import org.slf4j.LoggerFactory;
7.import org.springframework.stereotype.Service;
8.
9.@Service("simpleService")
10.public class SimpleService implements Serializable{
11.
12. private static final long serialVersionUID = 122323233244334343L;
13. private static final Logger logger = LoggerFactory.getLogger(SimpleService.class);
14.
15. public void testMethod(String triggerName){
16. //这里执行定时调度业务
17. logger.info(triggerName);
18. }
19.
20. public void testMethod2(){
21. logger.info("testMethod2");
22. }
23.}
package com.sundoctor.example.service;
import java.io.Serializable;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Service;
@Service("simpleService")
public class SimpleService implements Serializable{
private static final long serialVersionUID = 122323233244334343L;
private static final Logger logger = LoggerFactory.getLogger(SimpleService.class);
public void testMethod(String triggerName){
//这里执行定时调度业务
logger.info(triggerName);
}
public void testMethod2(){
logger.info("testMethod2");
}
}
SimpleService主要执行定时调度业务,在这里我只是简单打印一下log日志。SimpleService需要实现java.io.Serializable接口,否则会报

dataSource:项目中用到的数据源,里面包含了quartz用到的12张数据库表;

configLocation:用于指明quartz的配置文件的位置,如果不用spring配置quartz的话,本身quartz是通过一个配置文件进行配置的,默认名称是quartz.properties,里面配置的参数在quartz的doc文档中都有介绍,可以调整quartz,我在项目中也用这个文件部分的配置了一些属性,代码如下:

这里面没有数据源相关的配置部分,采用spring注入datasource的方式已经进行了配置。
六、测试
运行如下测试类
Java代码
1.package com.sundoctor.example.test;
2.
3.import java.text.ParseException;
4.import java.text.SimpleDateFormat;
5.import java.util.Date;

12.public class MainTest {

14. /**

16. */
17. public static void main(String[] args) {
18. ApplicationContext springContext = new ClassPathXmlApplicationContext(new String[]{"classpath:applicationContext.xml","classpath:applicationContext-quartz.xml"});
19. SchedulerService schedulerService = (SchedulerService)springContext.getBean("schedulerService");
20.
21. //执行业务逻辑...
22.
23. //设置调度任务
24. //每10秒中执行调试一次

31. schedulerService.schedule(startTime);
32.
33. //2009-06-01 21:50:00开始执行调度,2009-06-01 21:55:00结束执行调试

35.
36. //2009-06-01 21:50:00开始执行调度,执行5次结束
37. //schedulerService.schedule(startTime,null,5);
38.
39. //2009-06-01 21:50:00开始执行调度,每隔20秒执行一次,执行5次结束
40. //schedulerService.schedule(startTime,null,5,20);
41.
42. //等等,查看com.sundoctor.quartz.service.SchedulerService
43. }
44.
45. private static Date parse(String dateStr){
46. SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
47. try {
48. return format.parse(dateStr);
49. } catch (ParseException e) {
50. throw new RuntimeException(e);
51. }
52. }

54.}

这样只是简单的将quartz trigger名称打印出来。
这样通过SchedulerService就可以动态配置调度时间。其实SchedulerService 还可扩展,比如可以注入多个JobDetail,调度不同的JobDetail。
