Spring's support for quartz

Notice: spring3.1.1 does not seem to support quartz 2.x. This article is for quartz1.x.1. view code of the required software package (the following is the maven dependency configuration)

<dependency>            <groupId>${spring.groupId}</groupId>            <artifactId>spring-core</artifactId>        </dependency>        <dependency>            <groupId>${spring.groupId}</groupId>            <artifactId>spring-context</artifactId>        </dependency>        <dependency>            <groupId>${spring.groupId}</groupId>            <artifactId>spring-beans</artifactId>        </dependency>        <dependency>            <groupId>org.opensymphony.quartz</groupId>            <artifactId>quartz-all</artifactId>            <version>1.6.1</version>        </dependency>        <dependency>            <groupId>${spring.groupId}</groupId>            <artifactId>spring-context-support</artifactId>        </dependency>        <dependency>            <groupId>commons-collections</groupId>            <artifactId>commons-collections</artifactId>            <version>3.2.1</version>        </dependency>        <dependency>            <groupId>${spring.groupId}</groupId>            <artifactId>spring-tx</artifactId>        </dependency>

 

2. Support for the org. Quartz. Job Interface

Spring provides an abstract class org. springframework. Scheduling. Quartz. quartzjobbean to simplify the implementation of the job interface. The following code list:

Public class tensecondjob extends quartzjobbean {Private Static int times = 0; @ override protected void executeinternal (jobexecutioncontext arg0) throws jobexecutionexception {int seconds = (times ++) * 10; system. out. println ("10 seconds trigger:" + seconds + "seconds have passed! ");}}

3. Support for the org. Quartz. jobdetail class

Spring supports jobdetail in two ways,

3.1 provides a convenient Bean -- org. springframework. Scheduling. Quartz. jobdetailbean inherits jobdetail. The class declaration of this class is as follows:

public class JobDetailBean extends JobDetail        implements BeanNameAware, ApplicationContextAware, InitializingBean {}

Therefore, we can use jobdetailbean in the context configuration file to configure jobdetail:

<bean id="jobDetail" class="org.springframework.scheduling.quartz.JobDetailBean">        <property name="jobClass"            value="com.sin90lzc.train.train_spring_quartz.TenSecondJob"></property>    </bean>

 

3.2 provides a factory Bean -- org. springframework. Scheduling. Quartz. methodinvokingjobdetailfactorybean to generate the jobdetail object.

Methodinvokingjobdetailfactorybean uses a common JavaBean method to implement the job function. This is actually a proxy object that generates a job interface.

First, create a common JavaBean -- jobbean:

Public class jobbean {private int second = 0; Public void printpersecond () {system. Out. println ("second trigger:" + (second ++) + "passed! ");}}

The printpersecond method provides the function that a job should complete. You can configure methodinvokingjobdetailfactorybean to generate a jobdetail object.

　　<bean id="jobDetailCreateByFactaryBean"        class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">        <property name="targetObject">            <bean class="com.sin90lzc.train.train_spring_quartz.JobBean" />        </property>        <property name="targetMethod" value="printPerSecond"></property>        <property name="concurrent" value="true"></property>    </bean>

 

4. Spring's support for the org. Quartz. Trigger interface 4.1's support for org. Quartz. simpletrigger provides a convenient Bean -- org. springframework. Scheduling. Quartz. simpletriggerbean.

<bean id="simpleTrigger"        class="org.springframework.scheduling.quartz.SimpleTriggerBean">        <property name="jobDetail" ref="jobDetail"></property>        <property name="startDelay" value="0"></property>        <property name="repeatInterval" value="10000"></property>    </bean>

4.2 The support for org. Quartz. crontrigger provides a convenient Bean -- org. springframework. Scheduling. Quartz. crontriggerbean

<bean id="cronTrigger" class="org.springframework.scheduling.quartz.CronTriggerBean">        <property name="jobDetail" ref="jobDetailCreateByFactaryBean"></property>        <property name="cronExpression" value="* * * * * ? *"></property>    </bean>

5. Spring support for the org. Quartz. scheduler Interface

Spring provides a factory bean to generate the scheduler object. The following is the declaration of the factory Bean:

public class SchedulerFactoryBean extends SchedulerAccessor implements FactoryBean<Scheduler>, BeanNameAware,        ApplicationContextAware, InitializingBean, DisposableBean, SmartLifecycle {}

The following is an example of the configuration of schedulerfactorybean:

　　<bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">        <property name="triggers">            <list>                <ref bean="simpleTrigger" />                <ref bean="cronTrigger" />            </list>        </property>    </bean>

6. Test the code and configuration above.

public static void main(String[] args) throws Exception{        ApplicationContext context = new ClassPathXmlApplicationContext(                "applicationContext.xml");        //TimeUnit.MINUTES.sleep(10);    }
