@Async can also be used at the class level, in which case all of the class methods will be executed asynchronously.

Example

Using @Async on class level

package com.logicbig.example;

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

@Component
@Async
public class MyBean {

  public void runTask1() {
      System.out.printf("runTask1  thread: %s%n",
              Thread.currentThread().getName());
  }

  public void runTask2() {
      System.out.printf("runTask2  thread: %s%n",
              Thread.currentThread().getName());
  }
}

Main method

package com.logicbig.example;

import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.AnnotationConfigApplicationContext;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.core.task.TaskExecutor;
import org.springframework.scheduling.annotation.EnableAsync;
import org.springframework.scheduling.concurrent.ConcurrentTaskExecutor;
import org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor;

import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;

@EnableAsync
@ComponentScan
public class AsyncExample {

  public static void main(String[] args) {
      AnnotationConfigApplicationContext context =
              new AnnotationConfigApplicationContext(
                      AsyncExample.class);
      MyBean bean = context.getBean(MyBean.class);
      System.out.printf("calling async method from thread: %s%n",
              Thread.currentThread().getName());
      bean.runTask1();
      bean.runTask2();
  }
}

Output

calling async method from thread: com.logicbig.example.AsyncExample.main()
runTask1  thread: SimpleAsyncTaskExecutor-1
runTask2  thread: SimpleAsyncTaskExecutor-2
