Java ApacheCamel-JMS远程处理：未将异常抛出回生产者

我正在寻找一种解决方案，使消费者端抛出的异常在使用ApacheCamel-JMS远程处理时返回到生产者端

我发现有一个类似的问题已经被问到了

所以，我按照那里的答案，按照克劳斯的建议打开了transferException选项，但是Camel仍然给了我一个错误——一个不同的错误，由org.apache.camel.NoTypeConversionAvailableException引起的InvalidPayloadException-没有可用的类型转换器可将类型：org.apache.camel.RuntimeCamelException转换为所需类型：long，值为org.apache.camel.RuntimeCamelException:com.x.y.z.ServiceException:test]

因此，似乎我确实按照克劳斯的建议将异常转移到了生产者端（最初的异常被包装在RuntimeCalmeException中）。问题是我试图将我的异常转换为长返回类型

有没有一种方法可以让异常一直冒泡而不被转换

详情如下:

接口： PricingService.java

    public long getPrice(String id);

消费者端：PricingServiceImpl.java

    @Service("pricingService")
    public class PricingServiceImpl {
        public long getPrice(String id) {
            //only throw an exception here for simplicity. 
            //Assuming ServiceException is    serializable.
            throw new ServiceException("test");
        }
    }

RouteBuilder：

    public class MyRoutes extends RouteBuilder {
        public void configure() throws Exception {
            getContext().setTracing(true);
            from("jms:queue:pricingService concurrentConsumers=25&transferException=true&transferExchange=true").to("pricingService");
        }
    }

生产者方面：

    <camel:camelContext id="producer">
        <camel:proxy id="pricingService"
            serviceInterface="com.x.y.z.PricingService"
            serviceUrl="jms:queue:pricingService?transferExchange=true"/>
    </camel:camelContext>

谢谢

更新：

在producer端添加transferException之后，我得到的异常更改为以下内容。我真的无法理解这一点。它仍然试图进行转换。。。请帮忙。谢谢

您还应该在制作人端设置transferException=true。

谢谢您的回复。我试过了，但仍然得到了一个InvalidPayloadException，尽管底层异常有点不同：org.apache.camel.InvalidPayloadException：没有类型为：long但有值的正文：BeaniNotification public abstract long com.x.y.z.PricingService.getPrice（java.lang.String）抛出com.x.y.z.ServiceException和[test]]类型：org.apache.camel.component.bean.Beanin我更新了这个问题，但出现了包括堆栈跟踪在内的异常。评论部分的可读性不太好。如有任何意见，将不胜感激。谢谢
