一、获取quartz详情jar

<!-- quartz 的jar -->
<dependency>
    <groupId>org.quartz-scheduler</groupId>
    <artifactId>quartz</artifactId>
    <version>2.2.1</version>
</dependency>
<dependency>
    <groupId>org.quartz-scheduler</groupId>
    <artifactId>quartz-jobs</artifactId>
    <version>2.2.1</version>
</dependency>

二、相关代码案例

//Main.java启动类
public class Main {

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

//MyJob任务类
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);
    }

}

//applicationContext-scheduler.xml

    <!-- 定义任务bean -->
    <bean name="myJobDetail" class="org.springframework.scheduling.quartz.JobDetailFactoryBean">
        <!-- 指定具体的job类 -->
        <property name="jobClass" value="com.bky_lzw.quartz.MyJob" />
        <!-- 指定job的名称 -->
        <property name="name" value="myJob" />
        <!-- 指定job分组 -->
        <property name="group" value="jobs" />
        <!-- 必须设置为true，如果为false，当没有活动的触发器与之关联时会在调度器中删除该任务 -->
        <property name="durability" value="true" />
        <!-- 指定spring容器的key，如果不设定在job中的jobmap中是获取不到spring容器的 -->
        <property name="applicationContextJobDataKey" value="applicationContext" />
    </bean>
    
    <!-- 定义触发器 -->
    <bean id="cronTrigger" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
        <property name="jobDetail" ref="myJobDetail" />        
        <!-- 每一分钟执行一次 -->
        <property name="cronExpression" value="0/5 * * * * ?" />
    </bean>
    
    <!-- 定义调度器 -->
    <bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
        <property name="triggers">
            <list>
                <ref bean="cronTrigger" />
            </list>
        </property>
    </bean>
    
</beans>
