一 点睛

1 使用Quartz配置作业,两种方式

第一种：MethodInvokingJobDetailFactoryBean

调用myBean的printMessage方法

<bean id="simpleJobDetail"
    class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
    <property name="targetObject" ref="myBean" />
    <property name="targetMethod" value="printMessage" />
</bean>

MyBean类如下：

@Component("myBean")
public class MyBean {
    public void printMessage() {
        // 打印当前的执行时间，格式为2017-01-01 00:00:00
        Date date = new Date();
        SimpleDateFormat sf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
        System.out.println("MyBean Executes!" + sf.format(date));
    }
}

第二种：JobDetailFactoryBean

需要给作业传递数据，想更加灵活的话就使用这种方式

<bean id="firstComplexJobDetail"
    class="org.springframework.scheduling.quartz.JobDetailFactoryBean">
    <property name="jobClass"
        value="com.imooc.springquartz.quartz.FirstScheduledJob" />
    <property name="jobDataMap">
        <map>
            <entry key="anotherBean" value-ref="anotherBean" />
        </map>
    </property>
    <property name="Durability" value="true"/>                
</bean>

FirstScheduledJob类为：

public class FirstScheduledJob extends QuartzJobBean{
     private AnotherBean anotherBean;
     
     public void setAnotherBean(AnotherBean anotherBean){
         this.anotherBean = anotherBean;
     }

    @Override
    protected void executeInternal(JobExecutionContext arg0)
            throws JobExecutionException {
        Date date = new Date();
        SimpleDateFormat sf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
        System.out.println("FirstScheduledJob Executes!" + sf.format(date));
        this.anotherBean.printAnotherMessage();        
    }
}

AnotherBean类为：

@Component("anotherBean")
public class AnotherBean {
    public void printAnotherMessage() {
        System.out.println("AnotherMessage");
    }
}
