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">   
      
    
        
             
          
            
            
          
        <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">    
            <value>execute</value>  
        </property>  
    </bean>  
      
      
    <bean id="CronTriggerBean" class="org.springframework.scheduling.quartz.CronTriggerBean">  
        <property name="jobDetail" ref="SpringQtzJobMethod"></property>  
        <property name="cronExpression" value="/3 * * * * ?"></property>  
    </bean>  
      
      
    <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>
