Quartz作业调度基本使用详解

public interface Job {
    void execute(JobExecutionContext context)
        throws JobExecutionException;
}

<bean id="helloJob" class="com.example.jobs.HelloJob"/>

  JobDetail job = newJob(HelloJob.class)
      .withIdentity("helloJob", "group1") 
      .build();

    <bean id="jobDetail"
          class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
        <!-- 注入目标对象 -->
        <property name="targetObject" ref="helloJob"/>
        <!-- 注入目标方法 -->
        <property name="targetMethod" value="sayHello"/>
    </bean>

  Trigger trigger = newTrigger()
      .withIdentity("myTrigger", "group1")
      .startNow()
      .withSchedule(simpleSchedule()
          .withIntervalInSeconds(40)
          .repeatForever())            
      .build();

    <bean id="myTrigger" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
        <!-- 注入JobDetail -->
        <property name="jobDetail" ref="jobDetail"/>
        <!-- 指定触发的时间，基于Cron表达式 -->
        <property name="cronExpression">
            <!--<value>0 0 2 * * ?</value>-->
            <value>0/10 * * * * ?</value>
        </property>
    </bean>

        //注册trigger并启动scheduler
        scheduler.scheduleJob(job,trigger);
        scheduler.start();

    <!-- 注册一个统一的调度工厂，通过这个调度工厂调度任务 -->
    <bean id="scheduler" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
        <!-- 注入多个触发器 -->
        <property name="triggers">
            <list>
                <ref bean="myTrigger"/>
            </list>
        </property>
    </bean>

        scheduler.start();

    private boolean autoStartup = true;

        this.autoStartup = autoStartup;
    }
