Quick Start

@Configuration
@ComponentScan("com.example")
@EnableScheduling
@EnableAsync
@EnableCaching
public class AppConfig {

    @Bean
    public CacheManager cacheManager() {
        return new ConcurrentMapCacheManager("users");
    }
}

@Service
public class UserService {

    @Cacheable("users")
    public User getUser(Long id) {
        return userRepository.findById(id);
    }

    @Scheduled(fixedRate = 5000)
    public void scheduledTask() {
        // Runs every 5 seconds
    }

    @Async
    public CompletableFuture<String> asyncOperation() {
        return CompletableFuture.completedFuture("result");
    }
}
