How to use asynchronous processing in SpringBoot?

In SpringBoot, asynchronous processing can be achieved by using the @Async annotation. Start by adding the @EnableAsync annotation to the main class to enable asynchronous processing, then add the @Async annotation to the methods that need to be processed asynchronously.

Here is the sample code:

@SpringBootApplication
@EnableAsync
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

@Service
public class MyService {

    @Async
    public void asyncMethod() {
        // 异步处理的逻辑
    }
}

In the example above, the asyncMethod method in the MyService class uses the @Async annotation, indicating that this method will be processed asynchronously. When calling the asyncMethod method, Spring will start a new thread in the background to execute this method, without blocking the main thread.

It is important to note that when using asynchronous processing, make sure the methods are non-blocking, otherwise the asynchronous handling may not work. Additionally, asynchronous processing methods should not be called within the same class because Spring AOP is implemented based on proxies, and method calls within the same class will not be intercepted by the proxy.
