今天我们学习一下quartz的定时器的使用。年轻时我们放弃，以为那只是一段感情，后来才知道，那其实是一生。
quartz的简单实例
测试的项目结构如下：
一、pom.xml中定义quartz的依赖
<dependency> <groupId>org.quartz-scheduler</groupId> <artifactId>quartz</artifactId> <version>2.2.3</version> </dependency>
二、定义配置文件quartz.xml
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd"> <!-- 要调用的工作类 --> <bean id="quartzJob" class="com.linux.huhx.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="quartzJob" /> <!-- 调用类中的方法 --> <property name="targetMethod" value="work" /> </bean> <!-- 定义触发时间 --> <bean id="doTime" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean"> <property name="jobDetail" ref="jobtask"/> <!-- cron表达式 --> <property name="cronExpression" value="10,15,20 * * * * ?" /> </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>
三、定义任务的执行主体类QuartzJob
package com.linux.huhx.quartz; import org.springframework.context.Lifecycle; import org.springframework.context.SmartLifecycle; /** * Created by huhx on 2017-05-22. */ public class QuartzJob implements Lifecycle, SmartLifecycle { public void work() { System.out.println("Quartz的任务调度！！！"); } @Override public void start() { System.out.println("I am start"); } @Override public void stop() { System.out.println("I am stop"); } @Override public boolean isRunning() { return false; } @Override public boolean isAutoStartup() { return true; } @Override public void stop(Runnable callback) { } @Override public int getPhase() { return 0; } }
四、定义测试的主体类Main
public class Main { public static void main(String[] args) { ApplicationContext context = new ClassPathXmlApplicationContext("config/quartz.xml"); } }
五、运行的结果如下：
