Spring

Spring quartz Java XML 工作

简单的使用java Timer调度任务
首先写一个定时器任务类
Java代码

   1. package com.myspring.quartz;
   2.
   3. import java.util.TimerTask;
   4.
   5. public class MyTimeTask extends TimerTask {
   6.
   7.     @Override
   8.     public void run() {
   9.         // TODO Auto-generated method stub
10.         System.out.println("hello");
11.     }
12.
13. }

package com.myspring.quartz;

import java.util.TimerTask;

public class MyTimeTask extends TimerTask {

@Override
public void run() {
// TODO Auto-generated method stub
System.out.println("hello");
}

}

spring配置文件
Xml代码

   1. <?xml version="1.0" encoding="UTF-8"?>
   2. <beans xmlns="http://www.springframework.org/schema/beans"
   3.     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   4.     xmlns:p="http://www.springframework.org/schema/p"
   5.     xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">
   6.     <bean id="timeTask" class="com.myspring.quartz.MyTimeTask"></bean>
   7.     <bean id="myTimeTask" class="org.springframework.scheduling.timer.ScheduledTimerTask">
   8.         <property name="timerTask" ref="timeTask"></property>
   9.         
10.         <property name="period" value="1000"></property>
11.         
12.         <property name="delay" value="1000"></property>
13.     </bean>
14.     <bean class="org.springframework.scheduling.timer.TimerFactoryBean">
15.         <property name="scheduledTimerTasks">
16.             <list>
17.                 <ref bean="myTimeTask"/>
18.             </list>
19.         </property>
20.     </bean>
21. </beans>

<?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:p="http://www.springframework.org/schema/p"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">
<bean id="timeTask" class="com.myspring.quartz.MyTimeTask"></bean>
<bean id="myTimeTask" class="org.springframework.scheduling.timer.ScheduledTimerTask">
<property name="timerTask" ref="timeTask"></property>

<property name="period" value="1000"></property>

<property name="delay" value="1000"></property>
</bean>
<bean class="org.springframework.scheduling.timer.TimerFactoryBean">
<property name="scheduledTimerTasks">
<list>
<ref bean="myTimeTask"/>
</list>
</property>
</bean>
</beans>

局限性:Java Timer无法精确指定何时运行
使用Quartz调度器
同Java Timer一样首先创建一个任务类MyQuartzJob.java
Java代码

   1. package com.myspring.quartz;
   2.
   3. import org.quartz.JobExecutionContext;
   4. import org.quartz.JobExecutionException;
   5. import org.springframework.scheduling.quartz.*;
   6. public class MyQuartzJob extends QuartzJobBean{
   7.
   8.     @Override
   9.     protected void executeInternal(JobExecutionContext arg0)
10.             throws JobExecutionException {
11.         // TODO Auto-generated method stub
12.         System.out.println("方法调用");
13.     }
14.
15. }

package com.myspring.quartz;

import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.springframework.scheduling.quartz.*;
public class MyQuartzJob extends QuartzJobBean{

@Override
protected void executeInternal(JobExecutionContext arg0)
throws JobExecutionException {
// TODO Auto-generated method stub
System.out.println("方法调用");
}

}

添加spring配置
Xml代码

   1. <bean id="quartzJob" class="org.springframework.scheduling.quartz.JobDetailBean">
   2.         <property name="jobClass" value="com.myspring.quartz.MyQuartzJob"></property>
   3.         
   4.         <property name="jobDataAsMap">
   5.             <map></map>
   6.         </property>
   7.     </bean>
   8.
   9.     <bean id="simplerTrigger" class="org.springframework.scheduling.quartz.SimpleTriggerBean">
10.         <property name="jobDetail" ref="quartzJob"></property>
11.         
12.         <property name="startDelay" value="1000"></property>
13.         
14.         <property name="repeatInterval" value="1000"></property>
15.     </bean>

<bean id="quartzJob" class="org.springframework.scheduling.quartz.JobDetailBean">
<property name="jobClass" value="com.myspring.quartz.MyQuartzJob"></property>

<property name="jobDataAsMap">
<map></map>
</property>
</bean>

<bean id="simplerTrigger" class="org.springframework.scheduling.quartz.SimpleTriggerBean">
<property name="jobDetail" ref="quartzJob"></property>

<property name="startDelay" value="1000"></property>

<property name="repeatInterval" value="1000"></property>
</bean>

为了精确的控制调度工作,Quartz提供了cron工作
调度一个cron工作
例如,要在每天晚上11:59运行任务
可以如下配置spring配置
Xml代码

   1. <bean id="cronTrigger" class="org.springframework.scheduling.quartz.CronTriggerBean">
   2.         <property name="jobDetail" ref="quartzJob"></property>
   3.         <property name="cronExpression" value="0 59 23 * * ?"></property></bean>

<bean id="cronTrigger" class="org.springframework.scheduling.quartz.CronTriggerBean">
<property name="jobDetail" ref="quartzJob"></property>
<property name="cronExpression" value="0 59 23 * * ?"></property></bean>

我的主管写的cronExpression配置说明
最后启动工作,添加spring配置
Xml代码

   1. <bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
   2.         
   3.         <property name="triggers">
   4.             <list>
   5.                 <ref bean="simplerTrigger"/>
   6.                 <ref bean="cronTrigger"/>
   7.             </list>
   8.         </property>
   9.     </bean>

<bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">

<property name="triggers">
<list>
<ref bean="simplerTrigger"/>
<ref bean="cronTrigger"/>
</list>
</property>
</bean>

使用org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean类,直接调度任务,而不用继承QuartzJobBean
首先编写一个简单任务类MyQuartz.java
Java代码

   1. package com.myspring.quartz;
   2.
   3. public class MyQuartz {
   4.     public void hello(){
   5.         System.out.println("hello");
   6.     }
   7. }

package com.myspring.quartz;

public class MyQuartz {
public void hello(){
System.out.println("hello");
}
}

然后添加spring配置
Xml代码

   1. <bean id="myQuartz" class="com.myspring.quartz.MyQuartz"></bean>
   2.     <bean id="newJob" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
   3.         <property name="targetObject" ref="myQuartz"></property>
   4.         <property name="targetMethod" value="hello"></property>
   5.     </bean>

<bean id="myQuartz" class="com.myspring.quartz.MyQuartz"></bean>
<bean id="newJob" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
<property name="targetObject" ref="myQuartz"></property>
<property name="targetMethod" value="hello"></property>
</bean>

最后同理添加spring配置
Xml代码

   1. <bean id="simplerTrigger2" class="org.springframework.scheduling.quartz.SimpleTriggerBean">
   2.         <property name="jobDetail" ref="newJob"></property>
   3.         <property name="startDelay" value="1000"></property>
   4.         <property name="repeatInterval" value="1000"></property>
   5.     </bean>
   6. <bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
   7.         
   8.         <property name="triggers">
   9.             <list>
10.                 <ref bean="simplerTrigger2"/>
11.             </list>
12.         </property>
13.     </bean>
