在 @Async 注释的情况下，Aspect 中的验证异常被吞没

Question

我有一个方法定义为：

  @Async("queryTaskExecutor")
    @RateLimitation(rateSize = 10)
    public Future<RunQueryCommandResult> execute(final Path xmlPath,
                                                 final Boolean calculateAlreadyAllowedTraffic,
                                                 final String sessionId,
                                                 final boolean isQueryFromAFA,
                                                 final String mode) {}

RateLimitation 是针对每个方法执行的 RateLimiter 验证的自定义注释。触发方面的注释定义为：

@Aspect
public class RateLimitationAspect {
    private static final Logger log = LoggerFactory.getLogger(RateLimitationAspect.class);
    @Autowired
    RateLimitationValidator rateLimitationValidator;

    public RateLimitationAspect() {
    }

    @Before("@annotation(rateLimitation)")
    public void aroundRateLimitationAction(JoinPoint joinPoint, RateLimitation rateLimitation) throws Throwable {
        MethodSignature methodSignature = (MethodSignature)joinPoint.getSignature();
        Method method = methodSignature.getMethod();
        log.info("Validating rate limitation on method " + method.getName());
        if (!this.rateLimitationValidator.isValid(method, (ConstraintValidatorContext)null)) {
            throw new IllegalStateException(MessageFormat.format("Calling method [{0}] reached the maximum permitted calls per second, request is denied.", method.toString()));
        }
    }
}

我创建了一个测试来检查汇率验证：

 @Test(expected = IllegalStateException.class)
    public void test_execute_command_service_in_forbidden_amount_parallel()  {

        IntStream.range(1, 40).parallel().forEach(i ->
                runQueryCommandService.execute(XML_PATH, false, VALID_ALL_FIREWALLS_SESSION, false, QUERY)
        );
    }

测试失败，因为没有抛出 IllegalStateException。当我调试测试时，由于验证错误，IllegalStateException 确实在方面代码中被抛出。

吞下 llegalStateException。如果我从方法定义中删除 @Async 注释，则测试正常。请帮忙。

问题是调用带有@Async 注释的方法不会触发Spring bean 代理。我通过更改测试来调用控制器（调用被测试服务的那个）来解决它。然后按预期抛出并捕获异常。
