### 操作步骤 ###

第一步，引入jar包  
第二步，创建Job类  
第三步，将Job类配置到Spring容器  
第四步，将Job类配置到JobDetail  
第五步，配置调度触发器  
第六步，配置调度工厂

注意  
一个Job可以，有多个触发器  
一个触发器，只能够触发一个Job

### 引入jar包 ###

<dependency>
        <groupId>org.quartz-scheduler</groupId>
        <artifactId>quartz</artifactId>
        <version>2.2.2</version>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-context-support</artifactId>
        <version>4.1.3.RELEASE</version>
    </dependency>

### 创建Job ###

public class MyJob extends QuartzJobBean { 
    
        @Override
        protected void executeInternal(JobExecutionContext context) throws JobExecutionException {
            System.out.println("myJob 执行了............." + context.getTrigger().getKey().getName());
            ApplicationContext applicationContext = (ApplicationContext) context.getJobDetail().getJobDataMap()
                    .get("applicationContext");
            System.out.println("获取到的Spring容器是： " + applicationContext);
    
        }
    
    }

### 配置文件 ###

applicationContext-scheduler.xml

<?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" 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-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd">
    
        
        <bean name="myJobDetail" class="org.springframework.scheduling.quartz.JobDetailFactoryBean">
            
            <property name="jobClass" value="cn.itcast.quartz.MyJob" />
            
            <property name="name" value="myJob" />
            
            <property name="group" value="jobs" />
            
            <property name="durability" value="true"/>
            
            <property name="applicationContextJobDataKey" value="applicationContext"/>
        </bean>
    
        
        <bean id="cronTrigger" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
            <property name="jobDetail" ref="myJobDetail" />
            
            <property name="cronExpression" value="0/5 * * * * ?" />
        </bean>
    
        
        
        <bean id="cronTrigger2" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
            <property name="jobDetail" ref="myJobDetail" />
            
            <property name="cronExpression" value="0 */1 * * * ?" />
        </bean>
    
        
        <bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
            <property name="triggers">
                <list>
                    <ref bean="cronTrigger" />
                    <ref bean="cronTrigger2" />
                </list>
            </property>
        </bean>
    
    </beans>

### 启动Spring容器 ###

Quartz根据配置，定时执行任务

public class Main {
    
        public static void main(String[] args) {
            new ClassPathXmlApplicationContext("classpath:applicationContext-scheduler.xml");
        }
    
    }
