本文介绍如何使用 Spring 4.0.3 和 Quartz 2.2.1 通过 XML 配置文件实现定时任务调度。示例展示了配置 SchedulerFactoryBean、JobDetail 以及 CronTrigger 的过程，并提供了一个每隔 5 秒执行一次的任务示例。

Spring 任务调度（XML实现）

spring-4.0.3.RELEASE, quartz-2.2.1

1.applicationContext.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.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context.xsd">

	<import resource="applicationContext-task.xml"/>
</beans>

2.applicationContext-task.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"
    xmlns:task="http://www.springframework.org/schema/task"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context.xsd
        http://www.springframework.org/schema/task
        http://www.springframework.org/schema/task/spring-task.xsd">

	<bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
	    <property name="triggers">
	        <list>
	            <ref bean="cronTrigger" />
	        </list>
	    </property>
	</bean>
	
	<bean id="helloWorldTask" class="com.jin.service.HelloWorldTask"/>
	
	<bean id="helloWorldJobDetail" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
	    <property name="targetObject" ref="helloWorldTask" />
	    <property name="targetMethod" value="doSomething" />
	</bean>
	
	<bean id="cronTrigger" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
	    <property name="jobDetail" ref="helloWorldJobDetail" />
	    <!-- 每隔5秒执行一次 -->
	    <property name="cronExpression" value="0/5 * * * * ?" />
	    <!-- 延迟5秒再执行 -->
	    <property name="startDelay" value="5000" />
	</bean>
</beans>

3.测试类

package com.jin.service;

public class HelloWorldTask {
	private void doSomething() throws Exception
	{
		System.out.println("doSomething is invoked!");
	}
}

4.测试

package com.jin;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class ClientMain {
	public static void displayAllBean(ApplicationContext context)
	{
		String[] beans = context.getBeanDefinitionNames();
		
		for(String bean : beans)
			System.out.println(bean);
	}
	
	public static void main(String[] args) throws Exception {
		ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");
		
	}

}

输出结果：每隔5秒输出

doSomething is invoked!
