Use asynchronous @Async annotation in the SpringBoot project

The first step is to add @EnableAsync annotations to the startup class (must)
/**
   * starting program
 * 
 */
@SpringBootApplication
@EnableAsync
public class RuoYiApplication
{
    public static void main(String[] args)
    {
        
    }
}

The second step, in the controller, the method T (), remember that the asynchronous method cannot be called in the same type

@GetMapping("/list")
public void test01() throws Exception{

    batchPaymentService.t();
System.out.println ("After executing");
}

In the third step, adding annotations @Async (method Void and Future (waiting for asynchronous execution) in the service method to be asynchronous in the service layer

@Async
public void t() throws InterruptedException {
    System.out.println("1");
    Thread.sleep(10000);
    for (int i = 0; i < 100; i++) {
        System.out.println(i);
    }
    log.info("ttt");
}

The results of the execution can be seen that the asynchronous (first printed the execution, and the asynchronous method is printed)
