In SpringBoot, you can implement asynchronous task execution by using the @Async annotation to indicate that a method should be executed asynchronously. The specific steps are as follows:

  1. Enable asynchronous processing
@SpringBootApplication
@EnableAsync
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}
  1. Execute this asynchronously.
@Service
public class MyService {

    @Async
    public void asyncTask() {
        // 异步任务的逻辑代码
    }
}
  1. You can call the asynchronous method right where you need it.
@RestController
public class MyController {

    @Autowired
    private MyService myService;

    @GetMapping("/async-task")
    public String asyncTask() {
        myService.asyncTask();
        return "Async task started";
    }
}

This allows us to achieve asynchronous task execution in SpringBoot. It’s important to note that asynchronous task execution is implemented through a thread pool. By default, SpringBoot automatically configures a thread pool for executing asynchronous tasks, but it can also be customized.
