java - Camel Hystrix EIP - IgnoreExceptions 以防止调用 Fallback

Question

在Apache Camel Hystrix EIP中，如何防止调用错误请求异常的fallback方法。我尝试从请求调度程序处理器中抛出“HystrixBadRequestException”，但我仍然看到回退正在被触发。有什么办法可以解决这个问题吗？

 /* in route builder class */
public void configure() throws Exception {
    .hystrix()
        .hystrixConfiguration()
        .circuitBreakerEnabled(circuitBreakerConfig.isEnabled())
        .executionTimeoutInMilliseconds(circuitBreakerConfig.getConnectionTimeoutInMilliseconds())
        .circuitBreakerErrorThresholdPercentage(circuitBreakerConfig.getErrorThresholdPercentage())
        .circuitBreakerSleepWindowInMilliseconds(circuitBreakerConfig.getSleepWindowInMilliseconds())
        .circuitBreakerRequestVolumeThreshold(circuitBreakerConfig.getRequestVolumeThreshold())
        .metricsRollingStatisticalWindowInMilliseconds(circuitBreakerConfig.getRollingPercentileWindowInMilliseconds())
        .end()
            .to("requestDispatcher")
        .onFallback()
            .log(LoggingLevel.INFO, "Fallback:")
            .bean("responsehandler", "getFallbackResponse")
            .stop()
        .end()
}
    /* in dispatcher class */
private Exchange dispatchRequest(Exchange exchange) {
    if (exception instanceof HttpOperationFailedException) {
        Integer statusCode = ((HttpOperationFailedException) exception).getStatusCode();
        if(statusCode == 400) {
            throw new HystrixBadRequestException("Hystrix bad request");
        }
    }
}

目前camel-hystrix 中尚未实现此功能。我已经记录了一张票证，以便在即将发布的版本中添加此功能:https://issues.apache.org/jira/browse/CAMEL-13066
