Spring @EnableScheduling Annotation Example

By Arvind Rai, November 26, 2021
On this page we will learn using Spring @EnableScheduling annotation.
1. The @EnableScheduling enables scheduled task execution capability.
2. The @EnableScheduling is used on @Configuration classes.
3. The @Scheduled annotation is used to mark a method to be scheduled.
4. The <task:annotation-driven> XML namespace is equivalent to @EnableScheduling annotation.
5. The @EnableScheduling is introduced in Spring 3.1.
6. The @EnableScheduling is used as following.
@Configuration
@EnableScheduling
public class AppConfig {
   ------
} 




Using @EnableScheduling

AppConfig.java
package com.concretepage;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.scheduling.annotation.EnableScheduling;
@Configuration
@EnableScheduling
public class AppConfig {
	@Bean
	public Task task() {
		return new Task();
	}
} 
Task.java
package com.concretepage;
import org.springframework.scheduling.annotation.Scheduled;
public class Task {
	@Scheduled(fixedRate=2000)
	public void doTask(){
		System.out.println("do some task");
	}
} 
AppTest.java
package com.concretepage;
import java.sql.SQLException;
import org.springframework.boot.SpringApplication;
import org.springframework.context.ApplicationContext;
public class AppTest {
	public static void main(String[] args) throws SQLException {
		ApplicationContext context = SpringApplication.run(AppConfig.class);
	}
} 
Output
do some task
do some task
do some task
do some task
do some task
