Spring定时任务Quartz配置之手动设置

一 配置xml如下：

    <!-- 定时任务配置 -->
    <bean id="scheduler" class="org.springframework.scheduling.quartz.SchedulerFactoryBean" lazy-init="true">
        <!-- <property name="triggers">
            <list>
                <ref bean="t1" />
            </list>
        </property> -->
    </bean>

<!-- 配置作业类JobDetailBean -->
    <bean id="job1" class="org.springframework.scheduling.quartz.JobDetailBean">
        <property name="jobClass" value="test.Job1"></property>
        <property name="jobDataAsMap">
            <map>
                <entry key="timeout" value="0"></entry>
            </map>
        </property>
    </bean>
    
    <!-- 配置作业调度的触发方式（触发器） -->
    <!--  第二种CronTriggerBean，支持到指定时间运行一次，如每天12:00运行一次等。 -->
<!--     <bean id="cronTrigger" class="org.springframework.scheduling.quartz.CronTriggerBean">
        <property name="jobDetail" ref="job1" />  
        <property name="cronExpression" value="0 0 12 * * ?" />
    </bean>  -->
    
    <!-- 第一种SimpleTriggerBean，只支持按照一定频度调用任务，如每隔30分钟运行一次 -->
    <bean id="cronTrigger" class="org.springframework.scheduling.quartz.SimpleTriggerBean">  
        <property name="jobDetail" ref="job1" />  
        <property name="startDelay" value="0" /><!-- 调度工厂实例化后，经过0秒开始执行调度 -->  
        <property name="repeatInterval" value="2000" /><!-- 每2秒调度一次 -->  
    </bean> 

二 手动获取scheduler调度对象，触发SimpleTriggerBean对象，和作业类JobDetailBean对象

public class TestJob {
	public static  QuarzJobHelper jobHelper;
	/**任务调度对象*/
	private static Scheduler scheduler;
	static AbstractApplicationContext  context = new ClassPathXmlApplicationContext("classpath:/spring/applicationContext.xml");
	static{
		jobHelper = (QuarzJobHelper)context.getBean("jobHelper");
		/**任务调度对象*/
		scheduler = (Scheduler)context.getBean("scheduler");
	}
	public static void main(String[] args) {
		//从spring中获取trigger
		Trigger trigger = (Trigger)context.getBean("cronTrigger");
		//获取job作业类
		JobDetail detail = (JobDetail)context.getBean("job1");
		try {
			//新增job
			scheduler.scheduleJob(detail, trigger);
			System.out.println(detail.getName()+","+detail.getGroup());
			Thread.sleep(9000);
			//删除job
			scheduler.deleteJob(detail.getName(), detail.getGroup());
			//定时任务销毁
			scheduler.shutdown();
		} catch (Exception e) {
			e.printStackTrace();
		}
	}
