JavaEE进阶知识学习----Quartz-4-Quartz整合

###Quartz和SpringMVC，Spring整合
1.Quartz依赖的包如下：


org.springframework
spring-context-support
${spring.version}

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-tx</artifactId>
    <version>${spring.version}</version>
</dependency>

<dependency>
    <groupId>org.quartz-scheduler</groupId>
    <artifactId>quartz</artifactId>
    <version>2.2.3</version>
</dependency>

####使用Quartz配置作业的方式
第一种：MethodInvokingJobDetailFactoryBean，在dispatcher-servlet.xml中配置

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

SimpleTrigger的相关配置

<!-- 距离当前时间1秒之后执行，之后每隔两秒钟执行一次 -->
<bean id="mySimpleTrigger" class="org.springframework.scheduling.quartz.SimpleTriggerFactoryBean">
    <property name="jobDetail"  ref="simpleJobDetail"/>
    <property name="startDelay"  value="1000"/>
    <property name="repeatInterval"  value="2000"/>
</bean>

其中myBean的相关代码如下

@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，在dispatcher-servlet.xml中配置

<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>

anotherBean的相关代码如下：

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

FirstScheduledJob类相关代码如下
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();        
    }
}

myCronTrigger的相关配置如下

<!-- 每隔5秒钟执行一次 -->
<bean id="myCronTrigger" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
    <property name="jobDetail"  ref="firstComplexJobDetail"/>
    <property name="cronExpression"  value="0/5 * * ? * *"/>
</bean>

两种方法的Scheduler的相关配置

<bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
    <property name="jobDetails">
        <list>
            <ref bean="simpleJobDetail"/>
            <ref bean="firstComplexJobDetail"/>
        </list>
    </property>
    <property name="triggers">
        <list>
            <ref bean="mySimpleTrigger"/>
            <ref bean="myCronTrigger"/>
        </list>
    </property>
</bean>
