Question

我有一个使用http4组件的Camel 2.18.1路由，当我在uri选项中设置了throwExceptionOnFailure = false时，组件偶尔会抛出一个org.apache.http.NoHttpResponseException事件。

根据文件： -

如果throwExceptionOnFailure = false，则HttpOperationFailedException将不要因失败的响应代码而被抛出。这可以让你得到任何来自远程服务器的响应

我正在使用以下方式设置http呼叫： -

.setHeader(Exchange.HTTP_URI, simple("http://www.therealurl.com"))
.to("http4://dummyhost?throwExceptionOnFailure=false")

在Java DSL中，它适用于我为代理等设置的所有其他选项。

任何想法？
