springboot整合quartz

spring整合quartz

spring整合quartz網上有很多demo，大概說一下，因為springboot整合quartz在此基礎上整改的

第一步，加入相關依賴

    <properties>
        <springframework.version>4.3.7.RELEASE</springframework.version>
        <quartz.version>2.2.2</quartz.version>
    </properties>

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

        <dependency>
            <groupId>org.quartz-scheduler</groupId>
            <artifactId>quartz</artifactId>
            <version>${quartz.version}</version>
        </dependency>
    </dependencies>
    <build>
        <pluginManagement>
            <plugins>
                <plugin>
                    <groupId>org.apache.maven.plugins</groupId>
                    <artifactId>maven-compiler-plugin</artifactId>
                    <version>3.2</version>
                    <configuration>
                        <source>1.8</source>
                        <target>1.8</target>
                    </configuration>
                </plugin>
            </plugins>
        </pluginManagement>
    </build>

第二步，配置quartz的Scheduler(調度器)
有二種方式使用spring的quartz的job去配置Job（任務）

第一種是使用MethodInvokingJobDetailFactoryBean，配置如下：

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

第二種是使用JobDetailFactoryBean，第二種方式可以傳遞額外的參數給定時job

 <bean name="complexJobDetail"    class="org.springframework.scheduling.quartz.JobDetailFactoryBean">
        <property name="jobClass" value="com.zhihao.miao.ScheduledJob" />
        <property name="jobDataMap">
            <map>
                <entry key="anotherBean" value-ref="anotherBean" />
            </map>
        </property>
        <property name="durability" value="true" />
 </bean>

jobClass是一個擴展QuartzJobBean的類，它是一個Quartz作業接口的實現。在調用這個工作時，它被executeInternal方法調用。jobDataMap提供了將一些數據傳遞給基礎作業bean的機會。在這種情況下，我們傳遞一個將由ScheduledJob使用的bean“anotherBean”。

其實現如下：

public class ScheduledJob extends QuartzJobBean {


    private AnotherBean anotherBean;


    @Override
    protected void executeInternal(JobExecutionContext arg0)
            throws JobExecutionException {
        anotherBean.printAnotherMessage();
    }

    public void setAnotherBean(AnotherBean anotherBean) {
        this.anotherBean = anotherBean;
    }
}

第三步，配置Quartz Scheduler的Triggers（觸發器）

普通的觸發器，使用SimpleTriggerFactoryBean

<bean id="simpleTrigger"  class="org.springframework.scheduling.quartz.SimpleTriggerFactoryBean">
        <property name="jobDetail" ref="simpleJobDetail" />
        <property name="startDelay" value="1000" />
        <property name="repeatInterval" value="2000" />
</bean>

Cron觸發器，使用CronTriggerFactoryBean

 <bean id="cronTrigger"  class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
        <property name="jobDetail" ref="complexJobDetail" />
        <property name="cronExpression" value="0/1 * * ? * *" />
</bean>

第四步，配置SchedulerFactoryBean

  <bean  class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
        <property name="jobDetails">
            <list>
                <ref bean="simpleJobDetail" />
                <ref bean="complexJobDetail" />
            </list>
        </property>

        <property name="triggers">
            <list>
                <ref bean="simpleTrigger" />
                <ref bean="cronTrigger" />
            </list>
        </property>
    </bean>

完整的配置：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
                            http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd">

    <context:component-scan base-package="com.zhihao.miao" />


    <!-- For times when you just need to invoke a method on a specific object -->
    <bean id="simpleJobDetail" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
        <property name="targetObject" ref="myBean" />
        <property name="targetMethod" value="printMessage" />
    </bean>


    <!-- For times when you need more complex processing, passing data to the scheduled job -->
    <bean name="complexJobDetail"    class="org.springframework.scheduling.quartz.JobDetailFactoryBean">
        <property name="jobClass" value="com.zhihao.miao.ScheduledJob" />
        <property name="jobDataMap">
            <map>
                <entry key="anotherBean" value-ref="anotherBean" />
            </map>
        </property>
        <property name="durability" value="true" />
    </bean>


    <!-- Run the job every 2 seconds with initial delay of 1 second -->
    <bean id="simpleTrigger"  class="org.springframework.scheduling.quartz.SimpleTriggerFactoryBean">
        <property name="jobDetail" ref="simpleJobDetail" />
        <property name="startDelay" value="1000" />
        <property name="repeatInterval" value="2000" />
    </bean>


    <!-- Run the job every 5 seconds only on Weekends -->
    <bean id="cronTrigger"  class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
        <property name="jobDetail" ref="complexJobDetail" />
        <property name="cronExpression" value="0/1 * * ? * *" />
    </bean>


    <!-- Scheduler factory bean to glue together jobDetails and triggers to Configure Quartz Scheduler -->
    <bean  class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
        <property name="jobDetails">
            <list>
                <ref bean="simpleJobDetail" />
                <ref bean="complexJobDetail" />
            </list>
        </property>

        <property name="triggers">
            <list>
                <ref bean="simpleTrigger" />
                <ref bean="cronTrigger" />
            </list>
        </property>
    </bean>

</beans>

第五步，一些任務有關的實體類

@Component("myBean")
public class MyBean {

    public void printMessage() {
        System.out.println("I am called by MethodInvokingJobDetailFactoryBean using SimpleTriggerFactoryBean");
    }

}

@Component("anotherBean")
public class AnotherBean {

    public void printAnotherMessage(){
        System.out.println("I am called by Quartz jobBean using CronTriggerFactoryBean");
    }

}

public class ScheduledJob extends QuartzJobBean {


    private AnotherBean anotherBean;


    @Override
    protected void executeInternal(JobExecutionContext arg0)
            throws JobExecutionException {
        anotherBean.printAnotherMessage();
    }

    public void setAnotherBean(AnotherBean anotherBean) {
        this.anotherBean = anotherBean;
    }
}

第六步，啟動類：

public class AppMain {
    public static void main(String args[]){
        AbstractApplicationContext context = new ClassPathXmlApplicationContext("spring-common.xml");
    }

}

打印結果
