导入如下jar包:
commons-collections-3.2.jar
commons-logging.jar
jta.jar
log4j-1.2.15.jar
quartz-1.6.0.jar
spring.jar
配置time_bean.xml文件:
<?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:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.0.xsd"> <!--任务类 --> <bean id="myService" class="net.service.MyService" /> <!--调用任务类的对象,这个对象调用我们自己定义的任务类 --> <bean id="printTimerJob" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean"> <!--调用的任务类 --> <property name="targetObject" ref="myService" /> <!--调用任务类的pringLog方法 --> <property name="targetMethod" value="printLog" /> <!-- 是否并发 --> <property name="concurrent" value="false" /> </bean> <!-- 定义好调用模式: 如每隔2秒钟调用一次或每天的哪个时间调用一次等 --> <bean id="printTimerTrigger" class="org.springframework.scheduling.quartz.CronTriggerBean"> <!--将要调用任务类的对象引入进来 --> <property name="jobDetail" ref="printTimerJob" /> <!--没隔2秒 执行一次调用任务类的对象 --> <property name="cronExpression" value="0/2 * * * * ?" /> </bean> <!-- 启动定时器 --> <!--把定义好的任务放到调度(Scheduler)工厂里面--> <bean id="schedulerFactoryBean" class="org.springframework.scheduling.quartz.SchedulerFactoryBean"> <property name="applicationContextSchedulerContextKey" value="applicationContext" /> <property name="triggers"> <list> <!--将调度模式 引入进调度工厂中 --> <ref bean="printTimerTrigger" /> </list> </property> </bean> </beans>
配置web.xml文件(如果不配置此文件,直接运行测试类也可以,配置此文件就可以将定时器应用在web程序中)
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5"> <display-name>SpringQuartz</display-name> <!-- 加载spring的配置文件(一个或者多个) --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:time-bean.xml</param-value> </context-param> <!-- 配置spring监听器(作用就是启动Web容器时,自动装配applicationContext.xml文件的配置信息) --> <listener> <listener-class> org.springframework.web.context.ContextLoaderListener </listener-class> </listener> </web-app>
创建MyService类:
package net.service; public class MyService { public void printLog(){ System.out.println("输出日志"); } }
创建测试类
package net.test; import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; public class Test { public static void main(String[] args) { ApplicationContext act = new ClassPathXmlApplicationContext("time-bean.xml"); } }
