ThreadPoolTaskExecutor的线程名相同

以下是我对Executor的配置

@Configuration
@EnableAsync
public class AsyncServiceExecutorConfig extends AsyncConfigurerSupport {
    
    @Override
    public Executor getAsyncExecutor() {
        ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();

        executor.setCorePoolSize(xxx.getCorePoolSize());
        executor.setMaxPoolSize(xxx.getMaxPoolSize());
        executor.setQueueCapacity(xxx.getQueueCapacity());
        executor.setThreadNamePrefix("MyAsync-");
        executor.initialize();
        return executor;
    }
}

    Executor executor = asyncExecutorConfig.getAsyncExecutor();
    CompletableFuture.runAsync(() -> {
        
    }, executor);

当我打印出线程名时，它们都以MyAsync-1结尾

我在一个MyAsync-1中设置了Thread.sleep。下一个新线程仍然显示为MyAsync-1

我做错什么了吗？为什么它不给我MyAsync-2、MyAsync-3等
