1. Import dependencies

2. Create a scheduled task class

3. Configure the scheduled task executor

4. Project startup testing

To integrate scheduled tasks in Spring Boot, you can use the @Scheduled annotation provided by Spring Framework. The steps are as follows:

1. Import dependencies

Add the following dependencies in the pom.xml file:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter</artifactId>
    <version>2.5.0</version>
</dependency>

2. Create a scheduled task class

Create a class and add the annotation @EnableScheduling         to the class to indicate support for enabling scheduled tasks. Then add the @Scheduled annotation on the method that needs to execute the scheduled task to set the execution cycle of the task.

import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;

@Component
@EnableScheduling
public class MyTask {
    @Scheduled(cron = "0 0/1 * * * ?") // 每分钟执行一次
    public void myTask() {
        System.out.println("定时任务执行了！");
    }
}

3. Configure the scheduled task executor

Configure the scheduled task executor in the application.properties file, including the thread pool size, thread name prefix and other parameters:

spring.task.scheduling.pool.size=10
spring.task.scheduling.thread-name-prefix=my-scheduler-

4. Project startup testing

 At this point, the scheduled tasks have been successfully integrated.
