在 Spring 集成（入站网关）中传递非标准 Header 名称

Question

do you know a simple way how to add a non-standard Header name when using spring integration (inbound gateway). It looks like default class DefaultHttpHeaderMapper might be a key element but how can you gain an additional header name to the header. When sending a header with a name that is not included in the Spring Integration standard list of header names it is ignored. I want to use an additional one in a simple way.

Thanks a lot

Answer 1

The simplest way is to enable all the headers like this on the HttpInboundEndpointSupportSpec , when you use Java DSL for the Http.inboundGateway() :

.mappedRequestHeaders("*")

Another way is to use standard headers and a list of your custom:

.mappedRequestHeaders(DefaultHttpHeaderMapper.HTTP_REQUEST_HEADER_NAME_PATTERN, "my_custom_header1", "my_custom_header2")
