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>
