@Service
public class AsyncService {
    
    @Async
    public void asyncMethod() {
        // 异步执行
    }
    
    @Async
    public Future<String> asyncWithResult() {
        return new AsyncResult<>("result");
    }
}

@Bean
public Executor taskExecutor() {
    ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
    executor.setCorePoolSize(2);
    executor.setMaxPoolSize(10);
    executor.setQueueCapacity(100);
    executor.setThreadNamePrefix("async-");
    return executor;
}

总结

@Async简化了异步编程。
