maven依赖如下

<properties>  
        <springframework.version>3.0.5.RELEASE</springframework.version>  
    </properties>  
  
    <dependencies>  
        <dependency>  
            <groupId>org.springframework</groupId>  
            <artifactId>spring-context</artifactId>  
            <version>${springframework.version}</version>  
        </dependency>  
  
        <dependency>  
            <groupId>org.springframework</groupId>  
            <artifactId>spring-context-support</artifactId>  
            <version>${springframework.version}</version>  
        </dependency>  
  
        <dependency>  
            <groupId>org.springframework</groupId>  
            <artifactId>spring-tx</artifactId>  
            <version>${springframework.version}</version>  
        </dependency>  
  
        <dependency>  
            <groupId>org.springframework</groupId>  
            <artifactId>spring-web</artifactId>  
            <version>${springframework.version}</version>  
        </dependency>  
  
        <dependency>  
            <groupId>org.quartz-scheduler</groupId>  
            <artifactId>quartz</artifactId>  
            <version>1.8.5</version>  
        </dependency>

java代码如下：

package test;

import java.util.Date;

public class Test {  
    private static int counter = 0;  
    protected void execute()  {  
        long ms = System.currentTimeMillis();  
        System.out.println("\t\t" + new Date(ms));  
        System.out.println("(" + counter++ + ")");  
    }  
}

spring-config.xml内容如下：

<?xml version="1.0" encoding="UTF-8" ?>   
<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
     xmlns="http://www.springframework.org/schema/beans"  
     xsi:schemaLocation="http://www.springframework.org/schema/beans 
     http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">   
  

<!-- 配置调度程序quartz ，其中配置JobDetail有两种方式-->    
    <!--方式一：使用JobDetailBean，任务类必须实现Job接口 -->     
    <!-- <bean id="myjob" class="org.springframework.scheduling.quartz.JobDetailBean">    
     <property name="name" value="exampleJob"></property>    
     <property name="jobClass" value="test.Test"></property>   
     <property name="jobDataAsMap">  
<map>  
    <entry key="service"><value>simple is the beat</value></entry>  
</map>  
</property>
    </bean>  -->  
    <!--运行时请将方式一注释掉！ -->    
    <!-- 方式二：使用MethodInvokingJobDetailFactoryBean，任务类可以不实现Job接口，通过targetMethod指定调用方法-->    
    <!-- 定义目标bean和bean中的方法 -->  
    <bean id="SpringQtzJob" class="test.Test"/>  
    <bean id="SpringQtzJobMethod" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">  
    <property name="targetObject">  
        <ref bean="SpringQtzJob"/>  
    </property>  
    <property name="targetMethod">  <!-- 要执行的方法名称 -->  
        <value>execute</value>  
    </property>  
</bean>  
  
<!-- ======================== 调度触发器 ======================== -->  
<bean id="CronTriggerBean" class="org.springframework.scheduling.quartz.CronTriggerBean">  
    <property name="jobDetail" ref="SpringQtzJobMethod"></property>  
    <property name="cronExpression" value="/3 * * * * ?"></property>  
</bean>  
  
<!-- ======================== 调度工厂 ======================== -->  
<bean id="SpringJobSchedulerFactoryBean" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">  
    <property name="triggers">  
        <list>  
            <ref bean="CronTriggerBean"/>  
        </list>  
    </property>  
</bean>

</beans>

web.xml中配置spring

<context-param>  
        <param-name>contextConfigLocation</param-name>  
        <param-value>/WEB-INF/spring-config.xml</param-value>  
    </context-param>  
  
    <listener>  
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>  
    </listener>
