在本教程中，我们将看到如何使用Spring Quartz Scheduler或者如何使用Quartz进行Spring的作业。
我们已经看到了如何使用计时器和timertask安排作业。

我们可以使用两种方式指定石英作业。
MethodInvokingJobdetailFactoryBeanJobdetailFactoryBean.

MethodInVokingJobdetailFactoryBean用于更简单的任务。
它指定目标对象和目标方法，因此将在使用触发器指定的时间执行目标对象的方法。

项目结构：

使用MethodInvokingJobdetailFactoryBean创建Spring Quartz Scheduler示例的步骤：

步骤1：

使用名称"springquartzschedulemexample"创建简单的Java Maven项目。

步骤2：更新POM.xml以放置Spring Core和Spring Quartz依赖项。

pom.xml.

</project>

第3步：

在package com.igi.theitroad.spring中创建名为"sendemailtask.java"的类。

它是我们想要在特定时间或者时间间隔重复执行的代码的类。

package com.igi.theitroad.spring;
 
import java.util.Calendar;
 
public class SendEmailTask {
 
  public void sendEmail() {
       
    //You Jan want to put some condition for sending email
          //Actual email send logic   
    System.out.println("Sending email at "+ Calendar.getInstance().getTime());
   
  }
}

步骤4：在此步骤中，我们需要在SRC/MAIN/RESOUMENT中创建"Quartz-Config.xml"。
Quartz-config.xml将拥有安排任务所需的所有配置。
我们需要在这里放进四个条目

• 需要指定任务(sendemailtask)。
• 需要指定MethodInVokingJobdetailFactoryBean，它指定将执行的类和方法。
• 需要为触发器进行条目，该触发器指定时间间隔并启动延迟时间。
• 需要指定schedulefactorybean以将触发器和methodInvokingjobdetailFactoryBean一起绑定。

quartz-config.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" xmlns:context="http://www.springframework.org/schema/context"
 xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
             http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd">
 
 <!--Specify Task bean  -->
 <bean id="sendEmailTask" class="com.igi.theitroad.spring.SendEmailTask" 
 
 <!-- specifing class and method that is going to be called on a specified 
  time basis -->
 <bean id="emailJob"
  class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
  <property name="targetObject" ref="sendEmailTask" 
  <property name="targetMethod" value="sendEmail" 
 </bean>
 
 <!-- simple trigger specify repeat interval and delay time -->
 <bean id="simpleTrigger"
  class="org.springframework.scheduling.quartz.SimpleTriggerFactoryBean">
  <property name="jobDetail" ref="emailJob" 
  <property name="repeatInterval" value="10000" 
  <property name="startDelay" value="1000" 
 </bean>
 
 <!-- scheduler factory bean to put,the executing code and time intervals 
  together -->
 <bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
  <property name="jobDetails">
   <list>
    <ref bean="emailJob" 
   </list>
  </property>
  <property name="triggers">
   <list>
    <ref bean="simpleTrigger" 
   </list>
  </property>
 </bean>
 
</beans>

第5步：最后我们将创建主类来执行此功能。
我们将创建ClassPathxMlApplicationContext的对象加载Quartz-config.xml在package com.igi.theitroad.spring中的src/main/java中创建类名名称application.java

package com.igi.theitroad.spring;
 
/**
 * @author igi Mandliya
 *
 */
import org.springframework.context.support.ClassPathXmlApplicationContext;
 
public class Application {
 
public static void main(String[] args) throws Exception {
  new ClassPathXmlApplicationContext("quartz-config.xml");
 }
}

步骤6：当我们运行上面的程序时，我们将得到以下输出。
