How can I configure asynchronous requests in Spring Boot?

How can I configure asynchronous requests in Spring Boot?

You can configure asynchronous requests in Spring Boot by using the @Async annotation and enabling async support in your configuration.

What do I need to add to my application properties?

You need to add spring.task.execution.pool.size and spring.task.execution.pool.max-size to configure the thread pool.

Can you show me a code example?

Sure! Here's a simple example:

@EnableAsync
@Configuration
public class AsyncConfig {
    @Bean
    public Executor taskExecutor() {
        ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
        executor.setCorePoolSize(2);
        executor.setMaxPoolSize(5);
        executor.setQueueCapacity(500);
        executor.initialize();
        return executor;
    }
}

How do I call an async method?

You can call an async method by simply annotating it with @Async and returning a Future or CompletableFuture.
