如果我@Validated向我的服务的接口/实现添加注释,那么该服务不再是事务性的.Stacktrace显示没有,TransactionInterceptor但我只看到MethodValidationInterceptor.如果我删除@Validated然后我看到TransactionInterceptor并MethodValidationInterceptor消失当然.这些方面是否相互排斥？

@Service
//@Validated <- here is my problem :)
public interface AdminService {
  String test(String key, String result);
}

public class AdminServiceImpl implements AdminService, BeanNameAware, ApplicationContextAware {

  @Override
  @Transactional(transactionManager = "transactionManager")
  public String test(String key, String result) {

    return "hehe";
  }
}

@Configuration
@EnableAspectJAutoProxy(exposeProxy = true)
@EnableTransactionManagement(order = AspectPrecedence.TRANSACTION_MANAGEMENT_ORDER)
public class AppConfiguration {..}

我正在使用 Spring MVC 4.1 向一个安静的 web 服务添加速率限制。

我创建了一个@RateLimited可以应用于控制器方法的注释。Spring AOP 方面会拦截对这些方法的调用，并在请求过多时抛出异常：

@Aspect
@Component
@Order(Ordered.HIGHEST_PRECEDENCE)
public class RateLimitingAspect {

    @Autowired
    private RateLimitService rateLimitService;

    @Before("execution(* com.example..*.*(.., javax.servlet.ServletRequest+, ..)) " +
            "&& @annotation(com.example.RateLimited)")
    public void wait(JoinPoint jp) throws Throwable {

        ServletRequest request =
            Arrays
                .stream(jp.getArgs())
                .filter(Objects::nonNull)
                .filter(arg -> ServletRequest.class.isAssignableFrom(arg.getClass()))
                .map(ServletRequest.class::cast)
                .findFirst()
                .get();
        String ip = request.getRemoteAddr();
        int secondsToWait = rateLimitService.secondsUntilNextAllowedAttempt(ip);
        if (secondsToWait > 0) {
          throw new TooManyRequestsException(secondsToWait);
        }
    }

这一切都完美无缺，除非@RateLimited控制器方法的参数标记为@Valid，例如：

@RateLimited
@RequestMapping(method = RequestMethod.POST)
public HttpEntity<?> createAccount( …
