浅谈Spring中的Quartz配置

引用

Quartz是一个强大的企业级任务调度框架,Spring中继承并简化了Quartz,下面就看看在Spring中怎样配置Quartz.

被调度的类：

package timer.quartz;

import java.util.Date;
import org.apache.log4j.Logger;

/**
 * @Title: QuartzJob.java
 * @Package timer.quartz
 * @Description: TODO
 * @author [email protected] 
 * @date 2011-8-3 下午12:05:02
 * @version V1.0
 */
public class QuartzJob {
	private Logger logger = Logger.getLogger(this.getClass().getName());

	public void work() {
		logger.info("******开始进行任务调度******");
		//业务逻辑
		System.out.println("当前时间: " + new Date());
	}
}

配置文件quartz.xml：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">

<beans>
	<!-- 要调用的工作类 -->
	<bean id="quartzJob" class="timer.quartz.QuartzJob"></bean>

	<!-- 定义调用对象和调用对象的方法 -->
	<bean id="jobtask"
		class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
		<!-- 调用的类 -->
		<property name="targetObject">
			<ref bean="quartzJob" />
		</property>
		<!-- 调用类中的方法 -->
		<property name="targetMethod">
			<value>work</value>
		</property>
	</bean>

	<!-- 定义触发时间 -->
	<bean id="doTime" class="org.springframework.scheduling.quartz.CronTriggerBean">
		<property name="jobDetail">
			<ref bean="jobtask" />
		</property>
		<!-- cron表达式 -->
		<property name="cronExpression">
			<!-- 每隔10秒执行一次 -->
			<value>0/10 * * * * ?</value>
		</property>
	</bean>

	<!-- 总管理类 如果将lazy-init='false'那么容器启动就会执行调度程序 -->
	<bean id="startQuertz" lazy-init="false" autowire="no"
		class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
		<property name="triggers">
			<list>
				<ref bean="doTime" />
			</list>
		</property>
	</bean>
</beans>

测试程序：

package main;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

/**
 * @Title: QuartzJobMain.java
 * @Package main
 * @Description: TODO
 * @author [email protected] 
 * @date 2011-8-3 下午12:03:54
 * @version V1.0
 */
public class QuartzJobMain {

	public static void main(String[] args) {
        ApplicationContext context = new ClassPathXmlApplicationContext("quartz.xml");  
        //如果配置文件中将startQuertz bean的lazy-init设置为false 则不用实例化  
//        context.getBean("startQuertz");  
	}
}

配置文件web.xml：

<?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>webapps</display-name>
  
  <context-param>
  	<param-name>contextConfigLocation</param-name>
  	<param-value>/WEB-INF/classes/quartz.xml</param-value>
  </context-param>
  
  <servlet>
  	<servlet-name>context</servlet-name>
  	<servlet-class>
  		org.springframework.web.context.ContextLoaderServlet
  	</servlet-class>
  	<load-on-startup>1</load-on-startup>
  </servlet>
  
  <welcome-file-list>
    <welcome-file>index.html</welcome-file>
    <welcome-file>index.htm</welcome-file>
    <welcome-file>index.jsp</welcome-file>
    <welcome-file>default.html</welcome-file>
    <welcome-file>default.htm</welcome-file>
    <welcome-file>default.jsp</welcome-file>
  </welcome-file-list>
</web-app>
