The detailed steps of Taskun Scheduler framework and Spring integrated task scheduling
Taskun Scheduler is a lightweight Java task scheduling framework that can integrate with the Spring framework to achieve flexible and reliable task scheduling.This article will introduce how to use Taskun Scheduler framework with Spring for task scheduling.
Step 1: Add Taskun SCHEDULER and Spring dependence
First of all, we need to add Taskun Scheduler and Spring to the project construction file (eg, Pom.xml).You can find the latest versions of Taskun Scheduler and Spring in the Maven central warehouse, and add it to the dependence of the project.
<dependencies>
<!-- Taskun Scheduler -->
<dependency>
<groupId>com.github.seratch</groupId>
<artifactId>taskun-scheduler-core</artifactId>
<version>1.0.0</version>
</dependency>
<!-- Spring -->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
<version>5.3.10</version>
</dependency>
</dependencies>
Step 2: Create Spring configuration file
Next, create a Spring configuration file (such as ApplicationContext.xml) and add a set configuration to the file to the file.
<bean id="taskunJob" class="com.github.seratch.taskun.logging.TaskunJob" />
<bean id="taskunScheduler" class="com.github.seratch.taskun.scheduler.TaskunScheduler">
<property name="jobs">
<list>
<ref bean="taskunJob" />
</list>
</property>
</bean>
In the above configuration, we created an instance of Taskunjob and added it to TaskunScheduler.You can configure multiple jobs according to actual needs.
Step 3: Write the task class
Next, we need to write a specific task class.We can create a simple Java class, implement the Taskunjob interface, and rewrite the Execute method.In the Execute method, write specific task logic.
public class MyTask implements TaskunJob {
@Override
public void execute() {
// Execute specific task logic
System.out.println("Hello, Taskun Scheduler!");
}
}
Step 4: Configure the task class
In the Spring configuration file, the task class we write is configured to a Spring Bean.
<bean id="myTask" class="com.example.MyTask" />
Step 5: Add task scheduling annotation
Using Taskun SchedUler framework, we can define the scheduling rules of the task by adding annotations.In our task category, add @ScheDuled annotations and configure the corresponding scheduling rules.
@Scheduled(cron = "0 0/5 * * * ?")
public class MyTask implements TaskunJob {
@Override
public void execute() {
// Execute specific task logic
System.out.println("Hello, Taskun Scheduler!");
}
}
In the above example, we use CRON expressions to define the scheduling rules of the task.In this example, the task will be executed every 5 minutes.
Step 6: Run task scheduling
Finally, we need to start the task scheduler by creating an instance of TaskunscheDuler in the Spring configuration file.
<bean id="taskunScheduler" class="com.github.seratch.taskun.scheduler.TaskunScheduler">
<!-- ... -->
</bean>
<bean id="schedulerRunner" class="com.github.seratch.taskun.scheduler.SchedulerRunner" init-method="start">
<property name="taskunScheduler" ref="taskunScheduler" />
</bean>
In the above configuration, we configure TaskunScheduler to a Spring Bean and inject it into Schedulerrunner.The schedulerrunner here automatically executes the Start method when the Spring container starts to start the task scheduler.
At this point, we have completed the detailed steps between the Taskun SCHEDULER framework and Spring.Through these steps, we can realize flexible and reliable task scheduling and use annotations provided by Taskun Scheduler to define the scheduling rules.By integrating with Spring, we can manage and configure tasks more easily.
