处理异常时 Apache Camel CXF 空响应

这个问题与上一个问题相关： Apache Camel 多播、异常和聚合策略< /a>

我想我在问上一个问题时误解了这个问题。

我尝试处理我在路线中抛出的异常。

.filter(not(successResponsePredicate))
    .to("log:com.sdmo.Error?level="+LOG_LEVEL)
    .transform(simple("Erreur lors de l'appel copyItem"))
    .process(new ConvertCartResponseProcessor())
    .throwException(new Exception("copyItemError"))
.end()

异常是通过以下代码处理的：

onException(java.lang.Exception.class).handled(true).inOut("direct:thrownError");
from("direct:thrownError")
    .to("log:com.sdmo.output?level="+LOG_LEVEL);

我的路由由 cxf 端点启动，但是当异常处理路由实现时，返回到我的 WS 客户端的正文为空。

我对调试模式和日志进行了多次检查，以确保异常处理代码设置了响应，如果我用简单类型替换主体（POJO 类型），则在发送回复时会收到解组错误。

回复之前记录的最后一行显示正文定义良好：

INFO: Exchange[ExchangePattern:InOut, BodyType:com.access_commerce.cameleonws.cart.AddXMLResponse, Body:com.access_commerce.cameleonws.cart.AddXMLResponse@59dc73f9]

我猜我使用 InOut 模式或类似的东西有问题......

This question is related to the previous one : Apache Camel multicast, exception and Aggregation strategy

I think I missunderstood the problem when asking the previous question.

I try to handle exception I thrown in my route.

.filter(not(successResponsePredicate))
    .to("log:com.sdmo.Error?level="+LOG_LEVEL)
    .transform(simple("Erreur lors de l'appel copyItem"))
    .process(new ConvertCartResponseProcessor())
    .throwException(new Exception("copyItemError"))
.end()

The exception is handled through this code :

onException(java.lang.Exception.class).handled(true).inOut("direct:thrownError");
from("direct:thrownError")
    .to("log:com.sdmo.output?level="+LOG_LEVEL);

My route is started by a cxf endpoint, but when the exception handling route achieved, the body returned to my WS client is empty.

I made several check with the debug mode and the log to ensure that the exception handling code set a response, and if I replace the body (POJO type) by a simple type, I got an unmarshall error when sending the reply.

The last line logged before the reply show the body is well defined :

INFO: Exchange[ExchangePattern:InOut, BodyType:com.access_commerce.cameleonws.cart.AddXMLResponse, Body:com.access_commerce.cameleonws.cart.AddXMLResponse@59dc73f9]

I guess that there is something wrong with my use of the InOut pattern or something like...
