Spring结合quarzt可以实现更复杂的定时器，现做简单介绍相关配置：

<?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:task="http://www.springframework.org/schema/task"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-4.3.xsd
http://www.springframework.org/schema/task
http://www.springframework.org/schema/task/spring-task-4.3.xsd "> <description>spring-configuration</description> <bean id="timerTask" class="com.charles.spring.service.impl.TimerTaskImpl"></bean> <bean id="timerDetail" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
<property name="targetObject" ref="timerTask"></property>
<property name="targetMethod" value="doTimerTask"></property>
</bean> <bean id="simpleTrigger" class="org.springframework.scheduling.quartz.SimpleTriggerFactoryBean">
<property name="jobDetail" ref="timerDetail" />
<property name="startDelay" value="10000" />
<property name="repeatInterval" value="3000" />
</bean> <bean id="startTimer" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
<property name="triggers">
<list>
<ref bean="simpleTrigger" />
</list>
</property>
</bean></beans>

由于结合quartz的原因，需要相关quartz的Jar包，可到官网下载：http://www.quartz-scheduler.org/

接口与其实现类与Spring定时器实现(一)相同

package com.charles.spring.service.impl;import com.charles.spring.service.TimerTask;public class TimerTaskImpl implements TimerTask { @Override
public void doTimerTask() throws Exception {
System.out.println("Hello Timer");
}}

测试类：

package com.charles.spring.handler;import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;public class Timer { public static void main(String[] args) { @SuppressWarnings({ "unused", "resource" })
ApplicationContext context = new ClassPathXmlApplicationContext("config/spring-config.xml");
try {
Thread.sleep(10*60*1000);
} catch (Exception e) { } }}

以上算是Spring定时器第二种实现方式了，不过、目前还有另一种配置，如下：

<?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:task="http://www.springframework.org/schema/task"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-4.3.xsd
http://www.springframework.org/schema/task
http://www.springframework.org/schema/task/spring-task-4.3.xsd "> <description>spring-configuration</description> <bean id="timerTask" class="com.charles.spring.service.impl.TimerTaskImpl"></bean> <bean id="timerDetail" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
<property name="targetObject" ref="timerTask"></property>
<property name="targetMethod" value="doTimerTask"></property>
</bean> <bean id="cronTigger" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
<property name="jobDetail" ref="timerDetail"></property>
<property name="cronExpression">
<value>0/2 * * * * ?</value>
</property>
</bean> <bean id="startTimer" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
<property name="triggers">
<list>
<ref bean="cronTigger" />
</list>
</property>
</bean></beans>
