java - Camel HTTPS4 调用失败，但 CamelHttpResponseCode 标头显示 200

Question

我正在使用使用 https4 组件（camel 版本 2.14.0）通过 HTTP 请求资源的路由。死信通道通过将失败的交换路由到日志端点来处理错误，如下所示：

.to("log:backendFailed?level=WARN&showAll=true")

在网关超时 (504) 的情况下，将HttpOperationFailedException引发错误并按预期记录交换。自从我设置showAll=true了，所有的交换头都被记录了，包括CamelHttpResponseCode. 日志如下所示：

CamelFailureEndpoint=https4://backend?httpClient.socketTimeout=70000&httpClient.connectTimeout=70000,
...
CamelToEndpoint=log://backendFailed?level=WARN&showAll=true
...
CamelHttpResponseCode=200, 
CamelHttpUri=https://example.com/myresource, 
...
CaughtExceptionType: org.apache.camel.component.http4.HttpOperationFailedException, 
CaughtExceptionMessage: HTTP operation failed invoking https://example.com/myresource with statusCode: 504, StackTrace: org.apache.camel.component.http4.HttpOperationFailedException: HTTP operation failed invoking https://example.com/myresource with statusCode: 504

标题不应该在CamelHttpResponseCode这里说 504 吗？
