Quartz入門簡單案例，quartz入門

Quartz是一個任務調度架構。它可以在你指定的時間內去觸發某一個任務。

 

案例：

這裡的案例是基於Quartz 2.2.3、Maven、spring去開發完成的。

在pom.xml檔案中引入Maven相關依賴

第一步：建立一個作業類

 1 package cn.wy.test; 2  3 import java.text.SimpleDateFormat; 4 import java.util.Date; 5 /** 6  * 自訂作業類 7  */ 8 public class TestJob { 9     public void run(){//方法名可以任意取10         System.out.println("自訂的作業類型執行了："+new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(new Date()));11     }12 }

第二步：配置applicationContext.xml檔案

<?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">    <!-- 註冊自訂作業類 -->    <bean id="testJob" class="cn.wy.test.TestJob"></bean>    <!-- 配置JobDetail -->    <bean id="jobDeteil"        class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">        <!-- 注入目標對象 -->        <property name="targetObject" ref="testJob" />        <!-- 注入目標方法 -->        <property name="targetMethod" value="run" />    </bean>    <!-- 配置Trigger觸發器 -->    <bean id="myTrigger"        class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">        <!-- 注入任務詳情對象 -->        <property name="jobDetail" ref="jobDeteil" />        <!-- 注入cronExpression運算式，通過這個運算式指定出發的時間 -->        <property name="cronExpression">            <!-- 3秒後觸發，也就是相當於是TestJob類中的run方法每隔3秒執行一次 -->            <value>0/3 * * * * ?</value>        </property>    </bean>    <!-- 配置調度工廠 -->    <bean id="schedulerFactoryBean"        class="org.springframework.scheduling.quartz.SchedulerFactoryBean">        <!-- 注入Trigger觸發器 -->        <property name="triggers">            <list>                <ref bean="myTrigger" />                <!-- 可以同時配置多個觸發器 -->            </list>        </property>    </bean></beans>

第三步：測試

1 package cn.wy.test;2 3 import org.springframework.context.support.ClassPathXmlApplicationContext;4 5 public class Test {6     public static void main(String[] args) {7         new ClassPathXmlApplicationContext("applicationContext.xml");8     }9 }

執行結果：
