Quartz scheduling framework (Spring solution)

Quartz is a powerful open-source framework for scheduling tasks, making it easy for developers to schedule and manage tasks. In the Spring framework, Quartz can be used to schedule tasks.

Here are the steps to integrate Quartz with Spring solution.

1. Add dependencies: First, you need to add dependencies for Quartz and Spring’s support for Quartz in the project’s pom.xml file, for example:

<dependency>
    <groupId>org.quartz-scheduler</groupId>
    <artifactId>quartz</artifactId>
    <version>2.3.0</version>
</dependency>

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-context-support</artifactId>
    <version>5.2.6.RELEASE</version>
</dependency>

1. Factory bean for creating schedulers.

<bean id="schedulerFactoryBean" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="jobFactory" ref="jobFactory" />
    <property name="triggers">
        <list>
            <ref bean="cronTrigger" />
        </list>
    </property>
</bean>

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

<bean id="jobDetail" class="org.springframework.scheduling.quartz.JobDetailFactoryBean">
    <property name="jobClass" value="com.example.MyJob" />
</bean>

<bean id="jobFactory" class="org.springframework.scheduling.quartz.SpringBeanJobFactory" />

1. a job from the org.quartz package

public class MyJob implements Job {
    @Override
    public void execute(JobExecutionContext context) throws JobExecutionException {
        // 定时任务的逻辑
    }
}

1. Calendar Manager

@Autowired
private Scheduler scheduler;

public void startScheduler() throws SchedulerException {
    scheduler.start();
}

The steps for integrating the Quartz scheduling framework with Spring have been outlined above. Depending on specific needs, different schedulers, triggers, and timed tasks can be configured to achieve flexible scheduling and management of timed tasks.
