What are some examples of using async in Spring Boot?

In Spring Boot, you can use the @Async annotation to run methods asynchronously. Would you like to see a code example?

Yes, please provide a code example.

Sure! Here's a simple example:

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

@Service
public class AsyncService {
    @Async
    public void asyncMethod() {
        // Simulate a long-running task
        try {
            Thread.sleep(5000);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
        System.out.println("Async method executed!");
    }
}

You can call asyncMethod() from another method, and it will run in a separate thread.

How do I enable async support in my Spring Boot application?

To enable async support, you need to add the @EnableAsync annotation to your main application class. Here's how:

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.scheduling.annotation.EnableAsync;

@SpringBootApplication
@EnableAsync
public class MyApplication {
    public static void main(String[] args) {
        SpringApplication.run(MyApplication.class, args);
    }
}
