How can ExecutorService be integrated and configured in a Spring-based application?

In Spring, you can use the @EnableAsync annotation and configure a ThreadPoolTaskExecutor bean for injecting and setting up an ExecutorService.

Example configuration:

@Configuration
@EnableAsync
public class AsyncConfig {

    @Bean(name = "taskExecutor")
    public Executor taskExecutor() {
        ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
        executor.setCorePoolSize(5);
        executor.setMaxPoolSize(10);
        executor.setQueueCapacity(25);
        executor.setThreadNamePrefix("MyExecutor-");
        executor.initialize();
        return executor;
    }
}

Usage in a service:

@Service
public class MyService {

    @Async("taskExecutor")
    public void asyncMethod() {
        // asynchronous logic
    }
}

Thus, Spring manages the thread pool, and you can easily configure the parameters of the ExecutorService.
